2007 chevy cobalt with a 2.5 catback looking for a deeper sound wondering if going with zzp headers will give it a better sound

 

You want deeper sound? Try going with a V6 or better. On a serious note the more you open up your exhaust the more racecar it will sound. It won't get any deeper like a bass note.

 

You only need a header not "headers".....

 

Just had to go and point that out.......lol.

 

Yes. It's aggravating.

 

One for the front and one for the back. Lulz

 

keep your cat on there, what catback do you have?
if i were you id go with the zzp shorty an 2.5 dp catted or if your pockets are deep enough go with the longtube

 

Agreed.

To op, Idk what cat back you have but I have zzp mid length header/dp with gmpp 2.25 cat back(3rd setup I tried). Sounds deeper than any n/a 2.2 setup I have heard in person. Leave your cat, get which ever header/dp combo you can afford. If its not deep enough think about adding a resonator if your catback has a small one. My .02

 

Lmao I have this catback from amazon which they say it roughly 2.5 but it's probally 2.25 thinking going zzp downpipe any opinion on that

 

I had the zzp dp until I broke a weld when my giant resonator hit an elevated gas station fill hole (lol) cover. Was very happy it, only reason I replaced it was because I was sick of loosing a 2 year battle with my leaking pos badmab header and wanted it gone! If I was to do it again I'd probably go with ss/sc or zzp header, zzp dp. You may just have to play with muffler, resonator combos till you get the sound you want.

 

Thanks everyone for the feedbacks I got a good idea now

 

What didnyou decide to do. I'm also looking for a header and downpipe. I also have a 2.5 cat back.

 

I didn't buy anything yet but I'm leaning toward zzp downpipe

 

If by deeper you mean raspy and honda-like, go ahead. I wouldn't put a header on a 2.2 BUT THATS JUST ME

 

Haha not at all just something to give the car a better sound

 

I'm saying a header on a 2.2 will most likely make it raspy and annoying

 

I have a borla cat back on mine with headers and stock down pipe and cat and mine sounds deep

 

I forgot about borla. They made the original gmpp catback, not sure if they still do. Good **** either way.

 

should I post a video?

 

Hell yeah, lets hear that kitten purr.

 

Well, I jumped on a deal a guy had local. Had a 3" to 2.5" ZZP Highflow Catted 200 Cell Downpipe and a LSJ header. Now I'm 2.5" or more from the header all the way back. It definitely is louder, I say it feel Honda-ish but other people actually say it sounds a lot better then a Honda. Least it doesn't sound like I'm going 55 while only doing 5 mph.
