Hey Al,
I've been searching threads as to what kind of Downpipe and HF cat I should get, and also researching a testpipe.

I've found a couple places where people reference that you recommend the UR HF cat? Is this true? I'd like to hear why or why not.

Thanks

 

Hey Boomn29 where is your location located. St Louis or Seattle or other?

BTW how much louder is the 2.5in catback you have vs. stock?

 

Stl = St Louis.
I like the 2.5" a lot. It's a little droney when above 90mph, but hey that's probably expected. It sounds pretty neat (meaty) at low RPM's, and is just as quite at 3k crusing in 4-5th until you hop on the gas.
WOT is just sweet as hell!
