Just want to know how they are doing for those who have them. Are they holding up, do they perform well? Any down falls to them as far as fit and finish? I don't hear much about them, but I'm considering getting them for next years GNCC races. I want a nice pipe with a good sound, but not to load.

 

I can't comment on the pipes because I don't have any experience with them. But if Ironrod comments and says anything negative about them, please ignore him. He has alterior motives for saying every other pipe in the world is better and won't give you an honest unbiased reply. Good luck with your quest for honest feedback on them.

 

We run MBRP pipes on our grizzly and SP700 at work and they sounds good and seem to be holding up great! Id recommend them.

 

I have had MBRP's on mine since June. I love the way they sound, it pulls a little harder off the line and into mid, not much but enough to feel it. They turned a burnished color that I don't mind, sort of a burnt orange color. I think they were reasonably priced as well. Bbertram has sound clips on his website of them, look for one of his posts.

 

Yep they are good, probably not the biggest power making pipe on the market but then again they are cheaper and not nearly as loud as the competition. If you want straight up power Yoshi is the way to go. So far they are holding up well, they do turn a slight brownish after a few hot runs. I hear you can rub this brownish color out with some kind of liquid. I recommend them.

 

I have had the MBRP's for 3 months. The are VERY nice sounding pipes. Can't comment on the power as I did air intake and clutch mods at the same time I installed the pipe. Lots more power but how much the pipes make themselves, hard to say. Mine stll have the nice factory polish on them. You can clean them with a polish from Mothers but I forget the exact name. The header pipes will discolor from the heat which is a good indicator of how well you are jetted. If the color runs too far down the header, jet up.

 

Thanks for the info. Looks like the MBRP will be the way to go. I would rather have less power with a nice sound, then more power but loud. Now I just have to see if MBRP will be back on the forum.
