Cutting resonator pros or cons??

[KareemA4]

What are the pros or cons of cutting off the resonator on my exhaust.
my set up is a magnaflow dp back exhaust with a VMR testpipe

im assuming it will be louder and i will prob. hear more turbo spool??

the shop says $60 so i think its worth a shot

[jimrobbington]

I don't think you'll hear any more turbo. I have non-resonated exhaust on my b7 a4. It sounds great. And you might get an extra 1/4 of a horse power from it. I have a vid with sound clips of my new exhaust on you tube I can try to find real quick for you. it's a 2.0, but wouldn't be much different. I say for 60 bucks, do it. A tiny bit less restriction, and more sound.

hows the noise in the cabin??
any drone

my exhaust right now has no drone and is pretty quiet in the cabin

[jimrobbington]

In the cabin, Some quiet freaks might think it's a little droney, but I don't. It sounds great while you are driving it. Once you reach your speed, and stop accelerating, it's very quiet. Always noticeable when accelerating, no matter how fast. I would never go back.

I do not have data to back it up but common sense says that you will not see much/any gains from opening up the exhaust past the downpipe.

Especially since you already have an after market exhaust that is probably 2.5".

So if you do it, do it because you want a louder exhaust not gains.

[jimrobbington]

That's why I joked about the .25 horsepower. It can't hurt, but it won't help either. Sound is all you get! But that's totally worth 60 bucks.

Do you mean cutting out the resonators and the mufflers? Or just the resonators, and keep the mufflers?

I'd be skeptical to be honest. The drone might get to be unbearable at certain points (if its some, its fine, but what if it drones at 2500 RPM? Think of how often you're at that point). It also might not produce the sound you want. Straight pipes on a V8 sound fine, but I'm not sure how its going to sound on a turbo 4. Plus there's less backpressure in the system....

Think about it this way (and please don't take it the wrong way; I'm just trying to verbalize what I'm thinking): Think of how the OE and most aftermarket exhausts are designed: resonators, mufflers, cats. Cat/test pipe debate aside, if running the exhaust with no sound deadening was a good idea that produced a lot of benefits, don't you think more companies would build the exhaust that way from the start?

No because they have to deal with emissions and old people don't like loud exhausts.

Id like to see what the inside of the stock resonators look like, if they are start through and have no chambers or anything that redirects flow, they will probably just increase volume, however you probably wont see a gain in hp.

[KareemA4]

still keeping the mufflers on.
the car sounds good as is....im just looking for a more aggressive sound
and a louder spool
i heard it before on a MkI TT and it was amazing

[mattg1.8]

im thinking about doing the same thing. if you do it let us know how it turned out and what u think im curious

[QTC]

I'm 21. I don't like my exhaust loud. So I don't think its restricted to old people. Some people like the car loud, others soft. Remove all resonation, and it will be overkill for 99% of the people out there, which is why most exhausts come with mufflers and resonators. Emissions is a separate thing, hence why I sectioned off cats/tp's.

Then give it a whirl. Just save the parts in case you don't like it and want to put them back on.

[KareemA4]

Ok, im hopefully going tomorrow to get this done

any last suggestions??

[NvrFllw]

Cant wait to get my car back this week just to hear my non-resonated Magnaflow's drone like a mofo.

Yes, sell your car to me for 3000, ill even give you your non-resonated exhaust back as a keepsake! Is that ok with you?

The drone is that bad??

[Spinnetti]

I like racy exhaust (I road race in two series), but with my APR+test pipe W/O the resonator it was boomy as hell. It doesn't make the good sounds any louder, just the bad ones. Its not overly loud, just hugely annoying! Under full throttle it sounded GREAT, but sucked all the rest of the time, especially on the freeway where I do most of my driving (my wife and kids didn't mind, just me for some reason). I ended up putting a Vibrant in-line muffler in there to take some of the drone out. Didn't totally work, but much better. (pic of the modded pipe is in my pic poster)

[NvrFllw]

The drone is that bad??

I am use to it by now but to be honest I havent driven my car in two months so I have no idea if its going to be loud as hell like when I first got the exhaust on. I have been driving a diesel truck around so anything is quiet compared to that.

Since I got my car chipped the exhaust is a lot cleaner sounding and you can hear the turbo spool a lot better but it still drones but I love it

[KareemA4]

lol

and i have a magnflow exhaust so it would be the magnaflow resonator getting cut off

it would still make a difference in sound right?!

or is the magnaflow resonator straight through?

im so confused right now

[NvrFllw]

Hey got your PM but I was busy flaming some idiot in GCC.

Well having the resonator on there makes the car quieter. Taking it off will make it louder. My car isnt to bad. But if I have it in S mode and let the car rev low it drones. Throw it in TIP and rev the car high and then let off and let it slow down and it drones.

At first my ears were screaming but now I am use to it. I have been around loud muscle cars my entire life and use to race shifter karts so nothing it to loud lol. Try driving in a car with electronic dumps and your ears might bleed lol

[Jarim]

it will just be louder... no real gains.

little raspier if anything. $60 is pretty expensive to have them make 6 cuts and 4 welds.

they just have to cut the res. out and cut 2 lengths of pipe to fill the gap, weld em and your done.

should be more like $30-$40...

[robsilvr85]

I had my magnaflows put in and resonators taken out. Drone was annoying in the highway around 60mph..did have a nice aggresive tone when at WOT..but needless to say i had the resonators put back in. My .02

[KareemA4]

I woke up early this mourning and went and had it done.

It took about 40 minutes
when I turned on the car all I heard was rumble and it was amazing

I took it out for a test spin and man I hear sooo much spool and it pops everytime
I select a different gear

had the same feeling when I installed my testpipe...

And trust me, I'd go buy some mufflers from performancepeddler.com and use the coupon code "bestoffer4em"... You'll get a huge discount. around basically like 15%-25% off

While your at it pick up a flex section and some dual or bottle type resonators...

If you buy the parts yourself and bring them to be installed it will be WAY cheaper... Im talking $425 cheaper.

Just had 3" to dual 2.5" turboback exhaust built with magnaflow mufflers and resonator... Starting it up for the first time out of the shop was SEX!

Now i just waste hella gas cause im always trying to hear my exhaust haha... Not too much drone, a tad but minimal.

[NvrFllw]

He has an exhaust already. Why would he go buy another one?

[Jarim]

I was thinking he had the stock exhaust and wanted extra noise. Oops...

Well anyways... Does it drone real bad now with no res.?

With my system it drones a tad at WOT.

[jimrobbington]

I love the sound of mine, full turbo back, non res. Love it.

[Jarim]

I just didn't want mine loud as hell. Still pretty loud but toned down a bit and SUPER low/deep.

[NvrFllw]

Holland Tunnel in NYC is a great spot to hear your exhaust. Love the rumble and drone through there

[Duchenbagen]

I think that you should have just left your exhaust as it was. You are going to get tired of that rice. If you want that louder "SPOOL" get a big turbo or a carbonio.

[lisek99]

If I delete the resonator will I get CEL?

[Jarim]

How much louder is it?

[jimrobbington]

You will not get a CEL, only with a test pipe.

[jimrobbington]

I have never noticed the turbo get louder with exhaust, only an intake

[Jarim]

I have never noticed the turbo get louder with exhaust, only an intake

Testpipe makes the turbo ALOT louder and more noticable... and when i did my exhaust it got a tad louder aswell...

[KareemA4]

^^x2
so far the car sounds great
at low rpm there is a rumble and spool


at midrange it starts to get loud spool

and uptop it gets loud

drone isnt that noticible if you drive under 2k rpm
im a CVT btw

Could you please post a video, because I am thinking about deleting resonator too.
