Did they hook up that return piping off of the H-pipe that runs up the passenger side?
The stock exhaust has came with it.

The thermactor pipe?

Yeah, I guess that pipe really would hurt gas mileage, on second thought.
It must be something with his o2's like Zach said.

I love the sound of the exhaust but i the big percentage of gas mileage i lost sucks. One other thing i noticed was that one the pypes website it says it improves gas mileage, but the guy i talked to on the phone says that when you install this system you would loose about 1/2 mpg. Don't get me off wrong, im not vendor flaming, just asking a question.

But how do u like the sound? Are they as loud as 2 chamber Flows while cruising & at WOT? Also, how about the drone? I'm really lookin ino getting the same cat-back.
