anyone ever use this muffler by chance? or any of the kooks mufflers?

Muffler - Mufflers

 

i have them on my truck and love them.. go to my you tube. cordell weaver and its the 10th video down. true dual 3 inch supercharged kooks headers heads and cam. 410 rwhp. no cats.. there are a few other videos on their that have the kooks but most of them were dyno max mufflers.

 

I remember my buddy spent $2k++ for a complete kooks exhaust system for his Raptor, though I must say it sounds good.
