I'm looking for an exhaust system for my 2.4 SS non SC.. does anyone know which exhaust would give me the best possible hp, without sounding like its farting all over the place. i mean it has the stock exhaust which is ok. but i need some thing more. thnx guys

 

i have the GMPP Performance Exhasut on my SS/NA. I dont know of exact HP gains but ive heard around 12HP. sound is awesome and you dont lose your warranty

 

I was told that it was a little under 10...not sure though. I'm planning on getting mine in a month or so.

 

yeah it just varies. ive seen dynos from about 10-15HP

 

It was 12hp on an SS/SC, so don't expect that much N/A. As far as GMPP goes, the sound quality is very good, and it is alot cheaper than the Corsa.

 

makes sense

 

I would check out the Magnaflow since it is a 2 1/2 inch catback compared to the GMPP which is a 2 1/4.

 

GMPP performance exhaust is a great price with great sound and quality.

 

thanks guys i think thats what im gonna end up going with the gmpp.. anyone got a link i can get off line for the cheapest possible?

 

comparing HP for bolton parts is kinda silly.

when you go to a dyno you can get 214hp one run and 225hp next run with no changes.
so saying an exhaust with 10hp is better than an exhaust with 8hp is stupid.

Look at the quality of the part.
look at the measurements of the system, and do a little research on what size exhausts would benefit your type of vehicle. and remember, bigger doesnt always mean better.

when you shop for a bolton part....the HP number shouldnt be anywhere near the most important reason for buying a certain one.

 

custom exhaust! go to your local exhaust shop

 

anomalous what exhaust do you have?

 

I really like my corsa touring - nice deep sound and not too loud. Its quality is second to none. Plus, at 2.5" if you decide to turbo later, you won't need to swap it out from a 2.25" pipe. If you plan on staying n/a, 2.25" is all you really need though.

On the down side, it's very expensive. The best never comes cheap.

For the best $/hp just have a muffler shop build you a nice mandrel bent stainless pipe with a performance resonator and a magnaflow muffler for less than 1/2 the price of the Corsa.

 

thans sushidog, i was looking into the corsa, and yea there is an exhaust shop down the road, im gonna see what he can come up with, if not ill just got the corsa, or the gmpp

 

Has anyone heard things about the ARK Exhaust system for the Cobalt???

 

i say corsa sport, i love mine, deep sound, and jsut love it overall, its way worth the price

 

Question, i have the 2.4L SS, is the exhaust on a SS/SC different, i know its the catback but is it a different exhaust?. would it be worth it to swap exhausts for now?

 

What he said x2

 

the ark exhaust sounds really nice...deeep tone..couple of members have em

 

I have the GMPP performance exhaust.
Noticable HP gain, Great sound. Warrantied GM product.

IMHO I believe the corsa is a quality product too....but the extra money is only for a different sound.

 

yea im gonna check out my local exhaust place but the GMPP does look tempting

 

Corsa X10 it is the only one i would go with, dyno proven and sounds GREAT. The magnaflow has been having issues with the responator going bad and rattling...

We can get everyone a good price on corsa just have to PM us.

 

Four letters "GMPP"

 

yea looks like a close race between GMPP and the Corsa. ill let you guys know when i can get down to the local exhaust shop see what they have around

 

i went to a custom exhaust shop and got a 2 1/2 flowmaster super 40 series put on and it sounds great and it only cost 250 installed cant beat that.
