Hey gang,

I have searched for some specific fitment facts on different DP's on the STI. Some info is out there but not really specific. So, I would like to start this thread and have members give feedback on his/her own accounts when installing a specific DP to a stock STI cat-back.

Key topics of concern are listed below and could everyone follow the path and answer the topics in each reply?

1. Downpipe install on any STI with stock STI cat-back.
2. Does the Brand-X DP bolt to the stock STI cat-back...pros-cons?
3. Does the Brand-X DP account for CEL and how?
4. Does the Brand-X DP have a bung fitting for a tuning wide band O2?

Some brands I have come across and found interesting are....

Helix full length
Perrin full length
Daddys combo of Stromung+3CE
Cobb full length
Invidia full length
PDE full length

Cheers,

Dave

 

Some info here....nothing about additional O2 bungs.
