I've got a DIAMOND EYE with a CORSA muffler, but I was VERY limited with my options. I really like the CORSA muffler though, very quiet inside but makes it's presence known on the outside. When I drive past a wall or something I will often roll down the passenger side windows and romp her a bit just to hear the growl echo back.

I like whatever comes in a 5 inch. I think that is Silverline which is what all my friends have because it was cheaper.
Currently driving a 2007.5 RCLB 4x4 LMM W/T White. Basic Mods Stock Turbo Transgo Trans & Mike L trans.

A hole in LMM piston #1 At the moment and 7 was cracked. Awaiting rebuild.

12.67 and I have to find the slip again.

Furthest Pull this year was 359.XX and limited by concrete blocks.
