Exhaust note " NOISE!"

[NA_R33]

all u can do to reduce it is get a resonator, unfortunately it reduces the loudness factor in of ur exaust in general it does get rid of the aweful resonance, i have a resonator off a V8 commodore, it has 0 restriction and has almost totally eliminated the noise, it pretty much only does it when the car is cold now. On the plus side it gave the care really really deep note.

I only get the noise for about the first 5 minutes of driving, before and after cat&exhaust

Seems to go away by the time engine heats up

Maybe we should all fit turbo timers /joke

Ok, well looks as though nothing much can be done about it then, suppose ill just have to spend all the money on the new car!!!

I use to get that noise with the stock exhaust, roughly around 3000 rpm that lil flap would open and make that sound. after i changed the cat back the noise was gone. could also be the rear rego plate vibrating a bit?

yes i have the exact same noise but it doesnt bother me it tends to get quietter after a while ive always thought it was just the resonance in the exhaust

This noise got me defected yesterday, i knew it would happen, i was surprised i lasted this long with the noise. I might investigate into a full catback system now.

A v8 resonator hey??, might request for that aswell, i am over huge noise, im all for performance now.....as much as my na will provide anyway. Start with cat back, move onto cat, then incomes the extractors.

[NA_R33]

yep, they reckon they use it on the newer v8 commies and fords, he gave it too me for free cause he felt sorry for charging me for a new cat and it didnt even fix tghe problem, or if they know about it, ask for the resonator they use on twin cam corollas apparently these work even better.

My car does this as well, did it with stock exhaust and still does it with 2.5" cat back exhaust with TRUST stainless steel muffler (no resonators or additional mufflers).

As others have said seems to be worse when the car is cold, pisses me off cause I rev real slow leaving my street and it makes the noise around 2500rpm, sometimes I shift as soon as I hear the noise start cause I think it sounds sh*t.

Only ever does it around 2500rpm-3000rpm never high in the rev range.

Took it to exhaust shop the other day who installed my cat-back but he had NFI what it would be. He got under the car while I revved it but it didnt make the noise (I think it only does it when the car is under load).

It's embarressing when it makes that horrible noise!

Do you think it's worth getting a resonator put in?

I have no idea what this "noise" is, I'm going to try upload a sound file of my gts, tell me if this "noise" is there...

hmmm the file is 40mb lol... How can I make it smaller.. it's a video and soun file.. you don't really need to see the video part tho...

Hey all,

My noise was due to the heat shield. once removed horrible rattle tin sound disapeard.

Putting a decent resonator on your system eliminates it completely and as NA_33 said, although it becomes a bit quieter it sounds much deeper. I can relate to what all of you guys are saying, it kicks in around 2500/3000 rpm and makes an awful crackling/vibrating noise. I to was embaressed changing gears b/c the sound was that awful! Trust me, all you need is to put a good resonator in the piping, you'll be thankful.

that's almost like resurrecting jesus!

I know its an old thread but if anyone is reading Id highly suggest a resonator. A single muffer and cat will always sound awful on an NA car, a good muffler with a good quality resonator will really bring out the awesome note with out the horrible raspy/cackly noise.
