What I have found - is there is no good kit - unless you like mellow - I have found that if you want it loud or louder - buy a kit (or components of the kit - tail pipe and head pipe ) then add the muffler you like - I am in the process of building 2 exhaust systems right now - what I did and what I have done in the past.

 

Bullet mufflers are pretty good, not dynomax bullets, just bullets, u kan check em out here www.bulletperformance.com I heard em on a few trucks here in houston and they sound pretty mean and there only 80 buks each, not too bad
