GF, upon watching vid says: Wow, sounds so much better on video! FWIF...


YouTube - 2.4L Cobalt SC w/ZZP Header and 3" ZZP exhaust

 

We've got a new resonator about to become available. I'd be happy to discuss it with you. Maybe you could do a before after video?

 

If it quiets things down Zooomer I'd likely buy it. Idle is fine, WOT sounds ok (alright, better than ok going by the vid I just posted )....just that middle ground of daily driving that is too loud for what little is happening between speed and RPM.

 

Mark it doesnt sound that bad, definately a performance gain there. The only thing you could do to quiet it down is to change out the muffler for a dynomax super turbo muffler.

 

A new resonator could quiet it down over the one that came on the catback. In the eclipse world a v6 with headers and a catback is one of the raspiest cars ive ever heard. But on those a hushpower resonator takes away almost all the rasp and makes them almost sound like a nissna vq35.

YouTube - Eclipse RPW Header + Hushpower II resonator + Invidia Catback

ah the power of a resonator

 

cordia that eclipse sounds soo good. Can you get those hush power resonator to fit a cobalt or g5?

 

Should be able to. The exhaust room on the eclipse is similar to the cobalts.

 

MINE DOESNT SOUND NOTHING LIKE THAT! IDC if mine sounds loud but damn it sounds ricey... im gonna get my car back wednesday and then take a video then.

would any muffler fit this exhaust? cause its 3"

 

Isnt this a 3"? ive heard that thats too big tor a N/A engine. im running a 2.5 catback.
i was looking to do the upper end of my exaust too.

 

ya it is... but ottawa and I are both boosting. so that is why we went 3". Its just this thing is to ricey! if it sounded like ottawa I wouldnt be complaining but maybe its sounds like that cause his windows are up...

 

So what should I go with then. I'm staying na

 

Stay far away from 3" then, 2.5 is plenty for NA.

The ZZP Header bolt-in option connects to most 2.5 cat-back setups, you'll be pleased with their header, very sexy unit.

 

Yes. 2.5!!! if u are a 2.4 then ur stock exhaust is good man just change the muffler. Honestly I regret this stupid ricey sound! its not the 3 exhaust but the muffler. So just go with a different muffler.

Hey ottawa when u gonna get that new muffler? Cause Idk if I can get a universal muffler or if it has to be a certain size... let me know man im embarrased to even drive the car haha.

 

Alright I figured this out... yesterday I got my car back and tuned and ready to go! So I actually got to gun it. alright so this is whats up.... the zzp sounds great a low rpms and when u go WOT but from 3-4K rpms that ricey sound makes its way out... but its really noticeable when u are trying to speed up when u get into that rpm range... its sounds bad but at wot ur good and low rpms... What I do to avoid that high pitch ricey noise is to gradually go up in speed.... later I will get some vids of the car and its very loud... I dont mind that one bit. so overall it isnt as bad also it sounds worse in the car then outside. ottawa have someone else drive it and have them go WOT u might change ur mind... like I said it sound like a fart can btw those rpms then u cant notice... well I cant

 

Honestly I think either zzps new resonator or one like the hush power will help calm that sound.

 

honestly I can live with it. I rarely hit that rpm in dd but when I do i just left off and ease it down. but wot is alrigh ur video of the eclipse it does have a deeper tone to it but im ok with it I was drivin my friends celica while he drove mine and it was alright with me. I will get u vids cordia... urs will sound deeper as u arent going 3". Some part of me wishes i did but overall im ok.

 

i have to hear it now manny. and you got to take me for a drive

 

ya for sure! now that I can step on it sounds alot better. Like I said that 3K -4K rpms sounds raspy but other then that its all good! next meet man u can ride with

 

ok cool

 

Well typically larger exhausts sound a bit deeper. But will look forward to some videos. Problem for me is the slp isnt a resonated exhaust. So it could be very loud and raspy. Guess we will see come end of may.

 

Ya it has a low tone and low rpm I love it! I will get vids today

 

dont bother with it, its fiberglass packed and will just blow out and get loud


same muffler(design wise) but with SS packing

Stainless Works - Performance Exhausts and Headers

 

I dont have a stock exaust i have a 2.5" corsa catback

 

They dont make the longtube header in 2.5"

 

So unless some one can post a link for a 2.5" header/DP combo than I have to firsr make a decision between

2.5"

or 3"

I AM NOT GOING TURBO OR SUPERCHARGED
