06 with foulers and everything is still fine. For some that have the high flow cats and get the problem it could be like already stated not enough or too much exhaust gas. For sure the foulers work on test pipes. Turbo xs test pipes and foulers work great.

 

As I am looking to possibly get TP's instead of HFC's I have one major question...I see that many people get the non-foulers to get rid of the check engine light that will come on...however, other than just getting the light is there anything else that putting TP's on that affect the car/engine? Just seems based on this thread alone that the TP's and non-foulers the OP is using continue to put the check engine light on, but I gotta think there's more to him needing an answer than just the engine light.

Are these "cell" errors that are coming on an actual issue and affecting the eprformance or hurting the engine? I know this is a newb question, but I really don't understand the importance of these non-foulers if they are just to get rid of the light...

 

no dont worry...get tespipes

 

The "cel" from the non foulers will not hurt the performance or motor, the ecu just doesn't like not seeing a difference between the upstream and downstream o2 sensors.

 

So basically, based on what you two said, all the trouble is to just not have the check engine light on then? Good enough.

And is the fumes smell that bad and nasty?

 

IF you're sitting there idling you'll smell your exhaust and probably get light headed after a few minutes lol as long as you're moving you're fine.

 

just be sure if you have some installed you do them at a good exhaust company. The one i went to didnt locktite or even just tighten them down good. 02 sensor rattled out on the highway and hit a bump ripped off the wire now im out 180 for a new 02 sensor oem, and without my car for 5 days now waiting on it to get here. They dont stock 06 02 sensors cause not enough break.
