Well, I finally got tired of waiting on MRBP to get me the #'s. I called them several times and they would only say it gives good increases but could not provide #'s. Talked to Aaen and theirs has no spark arrestor and is very loud according to then which is weird because it says stock sound on web page. Trinity is way to much $. FMF still does not have out a mid pipe for theirs. So I just gave up and called HMF. Hopefully I wont regret it they show nice power gains all around. Any body running the HMF I would like to here your opinions. Rath told me that he has one and likes it alot but is under contract to run the WB.

 

If rath likes it but can't run it b/c of contract reasons...buy it up. Let me know what you think of it. Just a hint, just as well buy that quiet core along with it. It will run quieter than stock....so your pred will be a sleeper, sound stealth while waxing the competition.

 

I will let you know how it works. I got a buddy who has the WB so I will be able to get a good comparison. I didnt order the quiet core yet. I want to see what it sounds like first.
