DP issue!
 

so a while ago i sold my complete turbo back exhaust, no cat on the DP. I had a Perrin divorced DP with HKS hi-power. Well recently Rmac gave me his catted helix DP with greddy catback. The car bucks at 5k. Its gotta be the catted DP throw everything off.... what do you guys think?

Funny because i remove the negative on the battery drive it, pulls hard then after a few runs it bucks at 5k

If it is infact the cat, does anyone wanna buy a helix DP? possible the full exhaust so i can buy something that will work!!

its because youre ugly and ive been pounding your mom

lol, its all good. im still banging ashley on her UTI LMAO

the Perrin & HKS is 3.0"... what size is the GReddy? Also, who tuned you? You should just keep the exhaust and have nick (3gsucks) do a touch up tune

i pretty sure the greddy is a 3".

I'm sure it's just the extra backpressure... get it tuned and you *should* be fine, unless the cat is clogged or damaged (unlikely)

:-o

that is pretty much what i would figure too. I already talked to ryan earlier today and gave him a couple suggestions.

does anyone have a set of these locally. They normally come with cobb ap for the 2.0 wrx's

thinking about just getting the cat cut out.... unless someone wants to buy the complete exhaust.
