hey guys im fairly new to tuning cars and ive had the B&B turbo back exhaust on
for about 2-3 months now but havent been running the test pipe because of the check engine that it throws on....i ordered a perrin cat delete with the 02 simulator hoping that this will fix the problem and im waiting on that....but if ne one knows ne thing about this please let me know....thanks

 

It should work fine. Might be just a little louder, but this is a good thing right? Just make sure you do the o2 simulator install right. Here is a link to the "how to" on it. https://www.evolutionm.net/forums/sh...ad.php?t=90405

 

I did the "mechanical" o2 sensor fix, 3.99 at autozone.
