hey i wud like to buy a downpipe but idk wut one to get or where to get one please give me some choices

 

cobalt addiction,zzp,rebelmotorsports all are listed in the vendor index here.

 

i odrered a 3inch catless form cobalt addiction, the piece of **** flange wouldnt line up with my stock cat-back like they say it would. i tried drilling them bigger and it barely held together for a week, drove open dp for like a week and a half, then had a shop bend me the 3 inch all the way back. either they lie and say it will fit, or the one they sent me wasnt welded on straight.

 

thanks how did the car run wit open dp and how loud was it

 

weird. mine fit no problem, and i don't remember hearing from anyone else that it didn't fit.

will sound like ****, and be VERY loud. but not a good loud.

 

i was thinking of getting the 2.5 with a cat the 2.5 i preatty sure will bolt up to stock manifold and gm catback

 

yea, i had the 2.5" with cat and had no problems at all with fitment.

 

zzp has pretty good prices on their's, and you get it just about anyway you want it from them

 

cti header and downpipe combo all the way lol

made with either high flow cat or catless

he makes it when u order it

 

Do yourself a favor and get the ZZP Downpipe with Cat, excellent peice, good gains, no issues with fitment, nice sound

 

^^^ agreed i just got my 13/4 zzp header and my 3"downpipe with cat ...just got it back today and it sounds badass..def felt the increase right away and i only had just under a half tank

any body know how long should i wait to pounce on the pedal till it breaks in?

 

bout 500 miles or so.
