I got my Berk HFC's installed today. I did everything myself in my garage. I outwitted the dreaded "DEMON BOLT" too! Thanks to my little friend (Liquid Wrench Penetrating oil). I was shocked myself that it came out as easy as it did. All I used was 1/2" extensions and sockets with a breaker bar.
I took her for a spin and there is a definite sound difference under load. Plus the butt dyno was pretty happy. I can't wait to get my exhaust installed now! I will post pictures later
