ya i think ill go with the hi-flow cat, i don't want to worry about throwing cells and fixing crap along the way becuase of it.

 

^ if i recall, the 2 beta-testers for the 180TT/Q 42DD DP and tCarbon DP have yet to throw cel's with their DP/Testpipe setup.

 

I've used this guys o2 spacer eversince I put my DP on, no problems or cel's ever! spaethschmidt@yahoo.com

 

how much are they? you put on before and after cat? or just before (on the dp)

 

after the cat. the goal is to pull the 2nd (downstream) O2 sensor further out of the exhaust flow.

 

damn me and my fiance just went to look for cars for her and she made me sit in a god-damned chevy malibu!!!![:@][:@][:@]
All i could think about was blowing that son-of-a-b*tch up with a rocket launcher
I told her to get a VW or a toyota because she is "anti-coupe" she only wants 4 doors, and evo's don't count.

 

Take her to see either a Nice A4 1.8t or Allroad 2.7t

 

well I don't have a cat, but yeh the spacer goes on the post cat sensor. they were $35 shipped when I got mine about 6 months ago, you might want to email him to see the price now.
