THIS IS AN EXHAUST QUESTION ONLY..NOTHING BUT EXHAUST!!!

I used the Xtremeflow on mine. It was a direct replacement. One of the main things about it is that you don't have to change the 3" mandrel tail pipe that comes from the factory, so your not paying for tail pipes or tips. It has a clean agressive sound thats not to loud. The muffler is stainless and was designed for the H2 and not a retro fit from a truck application.

Also it is not a staight threw design.

It made the additional power they said.
