Okay i just installed AMS Full turbo back exhaust without cat. It is 3" all the way back without any restrictions. I am throwing a code now and i heard that a o2 fowler can fix the problem, meaning get rid of the code. I am assumingthe o2 sensor is reading way to much air now and is throwing the code. Anyone know where to get these?

 

You can also get the Tephra v5.10 mod for your ECU and that has a o2 simulator built right into it.

 

i have a perrin o2 simulator for sale if your interested...

 

o2 fowler has worked for me with no issues. i got mine off ebay for $12

 

DO you still have a link for the seller that you bought it from?

 

na, i bought it over a year ago.
this was the only thing i could find on ebay
