klr: That's assuming that you can control yourself enough to get better MPG with it on ...... I rev the hell out of my J30! 7k every day!!!

 

Actually since i've gotten my cat back installed, I've been riding it really hard...

I can't help it, i love the sound, and the performance boost... Yet I'm somehow still managing to get just about the same MPG (at this point, it's still spot on at 31mpg).

I'm surprised to say the least, but hey, i can't complain!

Now when I get my CAI installed this weekend, we'll see how that goes....

 

When I behave I can get about 22-23 MPG
