Seeking X-Pipe Feedback

[theweebabyseamus]

I was wondering about Sully's idea too. Might be a good option for a 'just better than stock' sounding exhaust. Suppose I couild give it a try when I finally acquire a stock exhaust...

[ofspecialk]

Dammit just realized I ordered the non-resonated X-pipe.... well it will be here tomorrow. should i install it or return it and get the 11385?

I want a little more volume, just not a lot of drone...

I was going to install it in place of the baby resonators, what do you guys recommend ?

From what im reading people seem much happier with the 11385 in place of the baby resonators and delete the second resonator....ugh I'll just cancel the order and get the 11385

At least you realized before you had the baby resonators cut out and are about to put the non-res unit in...or when you drive it out of the shop and think WTF.

true...especially since it needs to be ready for my meet by saturday lol.

Just straight pipe it from the headers back and make your presence known!

But seriously, don't actually do that. LOL

FWIW I love my non-resonated x pipe. More sound than the resonated with minimal (to me) drone. Exhaust stuff is so subjective. I had an Active Auto exhaust on my E92 M3 that people swore didn't drone and it killed me, so I'm not universally a drone-resistant person!

I find that there is drone between 1500 and 2800 rpm as you mentioned. It doesn't really bother me too much though. The resonated X-pipe may be something to consider.

I really want to thank everyone for their feedback! From the videos to the input I have gained quite some knowledge on these X-pipes! I decided to try the resonated X-Pipe and hope I can get in on soon. :)

I like my 11385. It's "just enough" and no drawbacks. It could actually be a little rougher/raspier, and I wouldn't mind. It's super smooth, and a nice little bump in volume so I can hear the car when heel-toe downshifting. Can't wait to go to the Blue Ridge Parkway between Cherokee and Waynesville to go through the tunnels and really hear what it sounds like outside the car

Drone on the exhaust is very subjective, I guest I have very little tolerance on drone. 🙉

It been a week I replacement my mid resonator with the Magnaflow resonated Xpipe, all the rest of the exhaust are completely stock. The sound is deeper, lower tone, I would say 15% louder in the exterior. As for the interior, it's not louder then before, with the Soundaktor at dynamic mode. Now, I can shut off the fake soundaktor and ear the nice son of the resonated Xpipe. Absolutely no drone, no matter how you drive the car. Very happy!!

So after reading through the giant thread about this, and this thread, the conclusion I am coming to is that there is no way to increase exhaust volume without proportionally adding drone. No matter which set up you use, or how much money you spend. Correct?

Does a resonated x pipe in place of the center resonator even add a worthwhile amount of volume?

Having read about half the giant thread and all of this one, there are plenty of people that have more volume and no drone? Resonated x pipe for the baby resonators and straight pipe the center. Minimal if any drone and more volume. But it's not like the aftermarket exhausts don't either...

Literally the post above yours mentions having no drone and more volume. Lol

This suggestion might not be a bad idea.

I recently had to remove my front Magnaflow resonated X-pipe because of some rattling issues and return it for a refund (thank you amazon!). I've since needed to reinstall the OEM downpipes with the OEM baby resonators. My exhaust got quieter, deeper, and unfortunately now I introduced drone because of the downshift in Hz. According to my sound meter, the drone between 2,000-2,300rpm is 107 Hz (I didn't get to measure my previous set-up). It's not rattle your interior drone, but the increase in the bassy/boomy noise in that RPM is there. The exhaust is louder in that rev range vs. any other range, whereas before, the exhaust note would increase as you gradually go up on throttle % as well as RPM range, your right foot controlled the amount of exhaust noise the car will make.

So for me:

setup #1: HFC ---> Magnaflow resonated X-pipe ---> Magnaflow resonated X-pipe ---> OEM mufflers = no drone, louder, higher frequency noises, more raw sounding
setup #2: HFC ---> OEM baby resonators ---> Magnaflow resonated X-pipe ---> OEM mufflers = quieter, deeper, drone, and muffled

I'm going to try replacing the OEM baby resonators with a non-resonated X-pipe to see if I can get a louder sound than set-up #1, even if it drones like set-up #2 (because it's entirely livable). At least if it still drones with the non-resonated X-pipe, at least it will be accompanied by a louder exhaust note overall.

Drone on the exhaust is very subjective, I guest I have very little tolerance on drone. ��

Hello,

The combination of those 2 constatations makes me think that the Double X-Pipe mod , all things OEM, could be a very nice option. A little more OEM like / Subtle than 1 Xpipe + straight piping center resonnator.

What do you think guys ?

I did some more reviewing and googled double x-pipe exhaust. Some aftermarket exhaust companies actually make this such as Corsa with their Double Helix X-pipe line of mid-pipes for the corvettes, silverados, mustang V8/V6 (which judging by the sound clip of the V6 stang, it sounds like a VR6 surprisingly). Also Camaro's, Pontiac GT's, and even some C63 amg guys run a double x-pipe arrangement, if not for any additional power (although Corsa does claim HP/TQ gains...), but to reduce interior resonance/drone, and to change the sound of the vehicle to a higher octave note versus a just simply a standard x-pipe.

I would say I accomplished that with my double resonated x-pipe arrangement in terms of reducing (actually eliminated) resonance/drone, and changing the sound of the car to a higher pitch without the rasp. With that being said, I do wonder if using one resonated + one non-resonated x-pipe would allow for a better sound without increasing drone due to the higher pitched exhaust note it already creates...only one way to find out!

Do you have a sound clip of your exhaust with the double resonated x-pipes? Very interested in the sound.

Thanks

I only have one video on page #1.

Just an update, I pitched my OEM baby resonators on the downpipes to install a non-resonated x-pipe. My drone is gone in the 2000-2,500 rpm range, and most importantly exhaust vibration in the 900-1,200 rpm range when the exhaust was cold is gone. The exhaust also gained volume as expected (like 10 folds!), but unfortunately also introduced some rasp in the 2,000- 3,000 rpm range which I'm hoping to cure by going back to my custom exhaust shop @ Crown Motorsports to do a custom double x-pipe arrangement in the mid-section or a very small resonator like this CLICK ME would do the trick in reducing the rasp without lowering the sound/pitch of the exhaust. I'm likely going to do something different with the double x-pipe mid-section arrangement (similar to a Corsa Double Helix X-pipe for Vettes/Mustang guys, a GT Pro for C63 guys, or Fabspeed mid-pipe for M3/M4 S55 engine guys) the more I listen to other cars sound clips on youtube as a before/after comparison. The best part of the volume gained was that it's determined by my right foot, meaning the more I put my foot into it, the louder the exhaust gets in the rev range. No matter how I drove the car, even after a few WOT runs, the exhaust would not drone/boom in the interior.

Right now: HFC - -> x-pipe where baby resonators were - - > resonated x-pipe where center resonator was - - > OEM mufflers

I actually wonder if this set up with OEM cats instead of HFC would be the answer to a louder exhaust everyone who does the x-pipe mod is looking for, without the rasp or drone? I say that because the HFC did introduced a bit of rasp on it's own due to its nature.

[Petatew]

I have magnaflow resonated x-pipe at the place of the baby resonator and only oem mufflers I find it perfect and no drone at all

[K2R1D3R]

Got my Resonated X-Pipe in today! Excited to get this on :)

Hey Loe, so am I understanding you correctly that you are next going to try a triple x-pipe configuration, with the non-res x-pipe replacing the baby resonators and then 2 x-pipes where the center resonator was? Both resonated, correct?

[AerotusX]

For those with 11385 replacing the baby resonators and "no drone", do you have manual or DSG. I'm interested in doing this also, but worried about my DSG introducing more drone.

yes, it sounds terrible. I don't recommend it. Well I take that back, the pitch of the exhaust note isn't bad, especially at WOT, its the rasp at part-throttle that needs work so it ruins it for me. The exhaust is pretty loud at WOT, zero drone too

Going to restore the OEM baby resonators and hook up one of the non-resonated X-pipe directly after it to change the pitch of the exhaust higher to avoid the drone (so back to a double x-pipe).
