Resonator or no resonator
 
Ok, I have heard that you are suppose to leave resonators but then I have heard taht you dont want them because of restriction. What am i better off doing? does anybody have any sound clips of an exaust with out resonators and with resonators?

help is much appreciated.

no resonator will make your exhaust more raspy and less rumble/drone...

Yes it will along with less back pressure. We need some of that. I say go with the resonator. :twothumbs

I'd leave em , your shit will be really raspy without it , and with a blown car you want a lil bit of restriction .

Psykostevo Feb 2, 2007 04:28 PM

Leave the resonator on.


I took mine off and I wish I never did! Sounds like a damn Honda.

Cobalt_SSTuner Feb 2, 2007 04:29 PM

do our cars have one or 2 resonators? I cant go look cuz my car is in storage ;)

D4u2s0t Feb 2, 2007 04:39 PM

i have a 2.5" catback, no resonator, and a 2.5" ca downpipe w/hi flo cat... i hate the sound, and i'm getting a resonator because it's WAY too raspy...

They have One

You don't need backpressure...

Hell, you want LESS backpressure. Exhaust velocity is what is important, not backpressure.

Why would you want restriction? The point of even changing your exhaust system is to get rid of restriction, hence, getting rid of backpressure.

D4u2s0t Feb 2, 2007 04:57 PM

well let me just say this... quick accelerations are HORRIBLY raspy, to the poing of being embarrassed...

indeed, backpressure is not a good thing, although traditionally, people err to side of some backpressure to keep gas speed up.

however, keep the damn resonator. if it didn't have a purpose, it wouldn't be on the flipping car.

If you take it off you won't like how it sounds.

an0malous Feb 2, 2007 07:32 PM

if less backpressure was the all important factor, then why do our cars run like shit and lose power if you run a cutout?

answer: less restriction is good. you want your engine to breath well but TO A POINT.


anyways. back on topic.

resonators are your friend. unless you like the sound of chainsaws....

It's mainly because there is a trade off. In order to get rid of restriction (for example: going with a larger diameter exhaust system), you're affecting your exhaust velocity. Larger the diameter, less backpressure being created, longer it takes to build up a high exhaust velocity.

This is why you can't go and get a 5" exhaust system and expect to gain power throughout your powerband.

Cobalt_SSTuner Feb 3, 2007 02:06 AM

I want a somewhat loud exhaust, I just dont want it to sound "restricted", yet I dont want it to be raspy as hell. I plan on going with a magnaflow muffler if that makes any difference. any thoughts? BTW, thanks for all of your help and support :cssNET:

Blown 4-banger Feb 3, 2007 02:25 AM

I have a pacesetter header, and 3" catless exhaust with a resonator and muffler. If I rev it neutral and your behind it, you will be momentarily deaf :lol: I'm having a second resonator welded in, the same time I get my wideband sensor welded in.

Cobalt_SSTuner Feb 3, 2007 02:28 AM

in your exhaust clip, is that with the resonator in?

Blown 4-banger Feb 3, 2007 02:30 AM

yes, and it was still loud as shit

Cobalt_SSTuner Feb 3, 2007 02:32 AM

see, i planned on going with a c-a header, xtc dp w/ high flow cat, and have the exhaust shop bulid me a custom exhaust w/ a magnaflow muffler.

Im readin your mail sir.

stvn Feb 3, 2007 01:21 PM

i have a magnaflow exhaust with no resonator and when i get on it in 2 3 and 4th gear it sounds like theres rocks in the muffler rattling around, and when i shift theres alot of poping.
