The Banks is nice, but way to expensive. You'll get the same sound and performance from something much cheaper, like Magnaflow or Flowmaster. The only people I see with Banks exhausts' (besides diesel guys) are the Titan boys. And I think the only reason they have it is put the ricer sticker on their trucks.
My buddy has an '03 Jeep TJ. Over the course of time, he's registered with a Jeep forum, and has enlisted my help in upping his power. One of the recent mods we've done was his exhaust. All of the Jeep guys swore by Banks for the 4.0. We put it on his, and man! It's got a mellow tone, not ricey at all. And it runs like a scalded dog
I found out one thing... Banks ain't just for oil-burners. :rck:
