alright so my i have a cobalt 2.2 07 wit a catless header back exhaust. it sounds like shit :lol: i kinda got to thinkin wouldnt it be better performance wise if i got a high flow cat because i'd have a lil back pressure and since i dont have f/i itll'd give me some more bottom end torque ?

dam wrong 2.2 section my b :lol:

In my opinion anything bigger than a 2.25" (GMPP) exhaust you will lose alot of low end torque on a 2.2. And there is absolutely no need for you to be going catless.

The 2.2's and LSJ motors dont need that much breathing room. The LNF would benefit the most from a more free flowing exhaust system.

yeah i was catless for about a week. wayyy to loud and stinky haha

yea catless was because i was broke at the time :lol: but im plannin on throwing on a high flow cat.. but i plan on running a 75/100 shot would i benefit from something bigger than a 2.25 inch

You could run a stock catback for street use and weld in the electric cutout im selling. Click the link in my sig.

I have an lsj dp on my 2.2 with a custom exhaust. Sounds nice.

cut out is only good for turbo on cycle lol imo.. yeah mine sounded great until i went catless

Turbo on cycle?

lol kinda wasted right now i ment cut outs are gud for 4 bangers on boost not n/a

It would be good for you if you plan on doing a 75-100 shot of nitrous.

idk lol

Your car will be quiet again! Shoot me an offer if you are interested.

ite no problem
