Burger Motorsports Exhaust Valve Flapper Bypass/Delete for RS5...anyone using these?

[Audi B8 S4]

Just saw where Burger Motorsports now offers an Exhaust Valve Flapper Bypass that allows for full-time sport mode sound in any driving mode without triggering fault codes or negatively affecting your tuning. Anybody here using these and if so what was your experience? Thanks!

I just had these installed but for different reasons.
Have the AWE exhaust installed and needed to completely remove the motors as they kept clicking back n forth at start up and also throwing soft codes.
Removed the motors completely and added the dummy plugs but still have soft codes but car runs fine.
Burger says it should not generate any codes so it could be something from my orig issue.

Hope this helps

Thanks for the update Mikriman!

I mean, I guess if you just want things loud 100% of the time, go for it.

If not, go the Cete AVC route.

Anyone else have difficulty installing these? I finally managed to get the right one installed but cannot get the left one. My hands just can't fit up in there (typing with bloody knuckles). Any suggestions?

I remember someone else suggesting that dropping the mufflers makes it much easier to access.

Are we supposed to be using the 3 or 4 position ones? Is there an install guide somewhere?

[Bezlar]

It’s pretty simple. Drop the rear section one at a time and install. Took about 15 min a side. You will need to have the back end jacked up.

cheers! Do you know if its the 3 or 4 position?

It’s still not very loud open all the time. My macan is louder stock.

I have them installed on my 2019 RS5 Sportback. Pretty happy with the valves permanently open. I get a few vibrations in the car at lower RPMs, but nothing too obnoxious.

[dal59]

These are actually a bit cheaper, when considering shipping and they come from the U.S., and you will get them much quicker.

Also, there is definitely a slight drone on highway at low rpm and a very noticeable vibration felt, especially in the center console. However, if you drop the tranny in to Sport mode, which drops it down a gear, they both almost go away completely.

I have a set of the Burger ones that I don't use, wife said it was to loud, so I went back to stock. $30 for the set and that's shipped, PM if interested.

I agree. Not bad at all! If I wanted a quiet car I would have bought a Tesla

I sent a PM about these a few days ago if you're still keen on selling

Immediately after installing them, I went for a ride. My initial reaction was that I had made a mistake by buying them and I could not wait to get home to tear them out. However, I decided to try them out for a while before making a final decision. I am glad I left them in. Now, I find myself shutting off the radio so I can listen to the sweet sound the car makes (Bull X deletes added as well).

The only thing I was concerned about was the talk on this forum of losing power with valves open all the time. However, my mechanic assured me this is not the case. Also, this did not make sense to me because as far as I know, when in Dynamic mode, under full throttle, these valves are open. Why would Audi have you lose power when you have the car in its "race" mode? So, as long as I have all my power when I need it, I am good,
and I am loving the sound.

What made you initially want to remove them? Just curious as I bought the Cete valve controller and pretty much will be driving with the valves open 90% of the time (I bought the controller for the 10% that I want a more subdued sound or I have a passenger/family in the car, otherwise I would have gone the delete plug route). Getting it installed in a few weeks...I also have the Bull-X pipes.

Well, I guess I was just use to the car being so very, very quiet unless under WOT and now you can hear the engine even when driving normally. It' not very loud, just different and sometimes it just takes me a little while to get use to change of any kind. I do not find it to be loud or annoying at all. I almost want to say the tone is now somewhat "exotic". You still have the pops and burbles, but now you have them all the time. Again, to me, this is a good thing.

There is a very slight drone on the highway, but it only seems noticeable during very slight acceleration. If you give it the gas normally, the car will downshift, and you will not hear it. I do not notice it while maintaining a steady speed. Now, I find myself putting the tranny in Sport mode more often as the car sounds even better and this appears to eliminate the little drone that I do get.

I said several times on here that to me this is a luxury car, and I did not want to make it loud and lose the luxury part. Now, I think it just sounds like a high-performance luxury car. If time and money were no object, I would probably go with the CETE controller just so I could close the valves on rare occasions, but for $56.00, I thought it was worth a try. Also, I do not believe the sound would interfere with a passenger or family in the car. The exhaust is now approximately the same volume of my Michelin A/S tires when on the highway at a steady speed. Hope this helps.

Helps a lot, thanks! The RS5 is a luxury car first for me as well, which is why I wouldn't be interested in a non-resonated aftermarket exhaust or anything like that (I've been there and done that with other cars I've owned). The mods I like on this car are very "OEM plus"...stuff that most people would mistaken for something that the car came with/like stock.

I got the Cete valve controller installed today and I was mostly impressed. It does exactly what it's supposed to and does it flawlessly. My biggest problem is the drone. In Dynamic there's no problem because the valves open all the time sounds awesome. However, when driving in Auto I found it to drone at highway speed or pretty much any time it up shifts and sits at low rpms. I could switch it to comfort, but there's almost no noise at all with the valves completely closed (I also found that there's a strange whooshing sound when you give it some hard throttle with the valves closed). I don't know, I was hoping Auto would stay exactly like it is without the controller but it's not. This is unfortunately going to end up in an expensive lesson learned for me as I'm having it removed. I still love the Bull-X pipes and think I'll be happy with just those. Perhaps it's the res delete that's making the drone worse...most likely it is, but I like that more than the controller.

On a side note, I also installed the 034 strut brace and I love the way it sharpened up the steering feel! That one is a relatively inexpensive winner in my opinion.

Thanks for the review. I was on the fence about CETE controller, especially since the installation is less than ideal with t-taps. I think I'll skip it and just go with a resonator delete. I'm assuming you don't notice any drone with just the resonator delete?

I'm also glad you posted the front strut brace review. I've put in all the 034 drivetrain inserts and have ordered the front and rear sway bars but I was unsure of the front strut brace since some people have commented you don't notice it during street driving.

I didn't notice any drone with the res delete. If there is any it's minor, and I'm fairly sensitive to any drone (I get that deep ringing in my ears and interior pieces rattle slightly...not fun). The strut brace isn't immediately noticeable and you start to think it's placebo, until I started taking some roundabouts that I go through everyday and that's where I noticed it 100%. Like the drivetrain inserts, it's subtle, but if you know the feel of your car it should be apparent enough and a worthwhile upgrade. It's also crazy how cheap the stock strut braces are...I don't know how they do anything. I feel like I could bend them in half with my hands.

Thanks, that's really helpful. I know some people don't mind the drone but it would drive me crazy. That's good to know about the strut brace too.

Thanks for the review. I am not familiar with how the CETE controller operates, but it sounds like it has the valves operating differently in different driving modes? Meaning, you cannot just have the valves stay open or close them whenever you want regardless of the driving mode. If this is correct, that may be one benefit to the valve bypass plugs (in addition to being cheap and easy to install). The sound that you love in Dynamic mode is the sound that you have all the time, regardless of the mode you are in. Now, that is assuming it's not too loud for you all the time. Dynamic, Auto and Comfort all sound the same.

Dynamic, Auto and Comfort all sound the same.

The Cete valve controller basic function is to keep the valves always open in Dynamic, always closed in Comfort, and to work the same way the OEM valves operate in Auto (or you can keep them full open or full closed regardless of drive mode). The problem I have, and I presume I would have with the bypass plugs, is that with the valves open in either Comfort or Auto the rpms drop too much or you're in to high of a gear and you get drone. In Dynamic, it keeps the revs up and an appropriate gear so the sound is fine. I'm assuming this is why the valves open and close in stock form even in Dynamic, so to keep the exhaust from droning as you let off the gas for long enough or start coasting (allow the transmission to jump to a higher gear). So what I'm getting at is yes I agree with you, regardless of whether I had the valve bypass plugs or this cete valve controller, I would only be happy with the operation in Dynamic (valves open all the time). Valves open all the time in Auto or Comfort creates too much drone for me...it's not how loud the exhaust is, it's just the drone. I'm sure all of this is exasperated by my Bull-X res delete pipes and maybe the valve controller or valve delete plugs would work just fine if the rest of the exhaust was still stock, but I really don't want to remove the Bull-X pipes to find out since I like the way they sound on their own, regardless of the wonky stock valve behaviour.

Okay, thank you for explaining how they work, and I fully understand what you are experiencing and your concerns. I have encountered the same drone issue with the bypass plugs. That is why I often keep the driving mode in Auto but put the tranny in Sport. By doing this, I get the sound you get while in Dynamic but with the balanced ride characteristics of Auto. And, like you, if push came to shove, I would pull the plugs, but I would not give up my resonator deletes.

Exactly! If I'm in Auto (but "D") it drones, and yes if I throw it into "S" while still being in Auto, the drone goes away (as it should since the rpms jump up). It's just not comfortable to cruise or do highway miles in Sport transmission (at least not for me...I know some people drive 100% in Dynamic or at least the transmission in Sport all the time).

Also, I'm not sure if it's just me, but I found with the valves fully open and in Dynamic, there seemed to be less burbles and cracks (although the overall sound volume was higher). Did you notice this with the valve plugs?

Honestly, I am not 100% sure. If there is a difference, it is not enough for me to tell. Sometimes, I even feel as though there may be a bit more but that may be because I am now driving more often in "S" mode. As you know, in "S" both the upshifts and downshifts are quicker, more frequent and more aggressive, and I feel this leads to more burbles and cracks. Maybe, even more so with the downshifts. Either way, in Auto - "S", I love the way it sounds.

I just installed these, and they work as advertised. I backed the car onto my race ramps, and dropped the exhaust to make them easier to get too as my hands were too big to squeeze in there otherwise. I also deleted my front resonators and am very happy with how it all sounds. Obviously not nearly as loud as my 911 with an awe track exhaust on it, but still nice none the less.

[Mav281]

Have you used a code reader to confirm you are not getting error codes?

I have these plugs installed as well and I get a soft error code using my OBDEleven device when I scan the car, even if I clear the codes they come back again. However the codes don't generate any dash lights and they do not appear to effect the performance of the car or the tuning as you have noted so I've left them in.

[ProudDaddy]

I just placed an order for these Burger plugs hoping they cure my issue with the AWE track exhaust (2021 RS5). I still hear the very annoying sound of the valves opening and closing even though they are not hooked up, woosh woosh.

Replying to my own post, the Burger plugs work and should be provided by AWE with every exhaust they sell for this car. Highly recommend to anyone that can't stand the obnoxious noise of the valve flap actuators. Kudos to Burger Motorsports for this $50 plug and play.

[bluonyx]

Yeah once the plugs are in you will have yourself some very nice billet paper weights. HAHA!
