What kind of tone or sound level difference does this have versus the catted H pipe? Also, I have the kooks LTH and catted H pipe on the car now, can the off-road replace the catted H pipe without a new tune?

  • The main difference when switching from a catted h-pipe to an off roadh-pipe would be the volume, the tone of the exhaust would be the same. The off-road h-pipe would make the exhaust louder than the catted h-pipe. Unfortunately, this mid pipe will need a tune since you will be deleting the catalytic converters.

Its the same size as the pipes leading to the axel back. How do I get the h pipe on?

  • The Kooks 3 in. Off-Road H-Pipe is reduced at the connection point to your cat-back to allow it to slide inside of the exhaust to be clamped in.

would this fit with the BBK long tube?

  • Unfortunately, the Kooks 3 in. Off-Road H-Pipe would not work with the BBK Long tube headers due to them being designed to work for the Kooks long tube headers.
