Test Pipe and O2 simulator on.

I have a Tanabe super racing medilian exhaust.

Results: No CEL, only been 60 miles though. Hopefully I have a new O2 simulator to offer to the board, built just for the S2000.

Sounds simular under Vtec, about 25% louder. In Vtec it's loud, but it was already loud. It's about the same 25% louder.

I can feel gains, no low end ones, but can tell a difference in the Vtec range. Also I haven't noticed any low end losses.

I will update next week after driving on it some more.

 

I have one and I just let the CEL stay on as it doesn't bother me. It seems to me that the VTEC transition is smoother with the test pipe. Although this is probably just a placebo affect.

 

my vtec transition is gone completely now

 

with the cel on I think that gas mileage is decreased and also HP to some extent, because the car is trying to heat the cat and there is no cat there so it keeps dumping fuel there. I remember when I first took the car out before the cel, it definitely pulled harder.
