I wonder why they chose to use only a 2-bolt setup for their mid-length header-to-b pipe combo. It seems that some people are having issues with leaking on that piece of the setup.

 

I'm a bit new to performace mods since my last 2 cars have been pos's, so I'm wondering what size DP I would need to adapt to a GMPP Performance Exaust and extruded manifold? Should I bother getting the GM header? If i get the header and catback exhaust installed and then buy the DP at a later date, is it an easy install for myself?
I just need some basic info so I know where to head, I have little experience with doing anything performance wise. All I know is I'm looking to get Stage 2 and the Header/Exhaust, and leaving the stock DP in there would be a bottle-neck for the whole flow. Any suggestions?

 

i've got the same header and downpipe on my ss too. love it! good choice!

 

seriously guys.... can anyone get me sound clips?? i would really love to hear the difference from stock and with the header DP combo

 

thats the paint burning off the header. high temp pain is worthless when you have egt's like ours.

 

im getting my install at the local shop..wed...i try to get sound clips on a ss/na

 

i got mine installed....i been trying to drive it easily....i hear a whisper sound if i rev it up 4rpms...any ideas...probably needs to get broken it?

Seriously nice header, def the one I'm gonna pick up.......and dont worry I'll post vids

 

i just got the ZZP 2.5 Cat DP. going to install in the second week of septemeber. Once they intsalled the ZZP DP did yall pop any cels ?

 

sorry just looking at getting it .. and i'm just curious as to how it sounds, and once I can drop the cash we're good to go

 

I got a CEL with my set up. Sucks. I can clear it, but it keeps coming back. I'm going to get someone with HPT to fix it for me

 

No CEL for me
