I actually don't have the test pipe like I stated, I meant to say I have the Berk's HFC. Think the inners of the cat are on their way out. Haven't had a CEL for about 10 days now, haven't made any changes.

For the guy asking about me only getting 21.5mpg, you come drive in Guam where there is only city traffic and no highways and if your car does better, then you drive like a pansy. hahaha

 

Well, it's been over a week and still no CEL.

 

Just a little update for you 06+ guys...

It's been about a month and still no CEL.
