Before you guys rip my head off like usuall i allready hit the search button. I just received my Invidia TP and a Helix DP, I have a HKS catback. I was wondering with my 02 fix that i have, do i have to get welded to the TP for can i just screw it into the 02 sensor bung in my catback. Most of the threads i read said there 02 fix is in thereTP.

 

The IX's rear o2 is in the cat, it is in the mid pipe section on our VIII's.

You will be fine.

 

cool thanks

 

you should not have to weld an o2 cel fix at all u can get ones that screw into the bung on your catback and fix the cel.

 

oh by the way your freakin exhaust sounds awsome!!!!

 

Thanks
