Install a 2 1/2" with a 2" H pipe and put on some mufflers. It won't scrape and it will sound like it should.
Chambered pipe is too loud.

Chambered pipes are on the way so i'm in for however they sound. I think with downsizing from 3" to 2.5" and all new pipes it will very good from the clips i have heard. Stu
