I was going to get the Yosh pipe until a friend of mine got it and didnt really notice a difference, so I spoke to a few buddies and went with the Trinity and heck you cant loose, they give you a 30 day money back gaurantee!!! And you know what?? I know I gained at least 8 hp with their pipe and their jets. Then I added the Alba K&N proflow kit. I couldnt believe the lid on the airbox, its like pushing a river thru a hose, so that came off as well. I love the sound and the power!! You will not be dissappointed, get the Trinity. Not only does it look good but the power that it gives both top and bottom end are excellent in my book.
