Muzzy pro pipe-Doug or other end users?
Currently i have the step hindle exhaust on my carpenter built 1290. My bike has an extended ecu from Dave O., 13.5 pistons,headwork, carpenter cams(110-112), dry nos etc.
Given an educated guess what kind of hp gain would i see over my step hindle? Would this pipe ruin the streetabilty? Would i have to remap the bike? I'm still looking to squeeze every hp out of my current set up. I would consider a sidewinder but i wouldn't be able to use it in the twisties.

If you lower the bike enough to actually NEED a sidewinder , forget the curves!
Yes you would need to remap for any pipe change.

110 / 112?? I have seen trhese numbers but they look a bit wild to me! (In other words totally biased in 1 direction! Are these his cams and what he is setting them to?

Yep those are carpenter cams set up by the man himself. The only reason i know what the cams specs are is last year the stock clutch basket took a dump and my mechanic told me.
Anyway how about any educated thoughts on my built motor with the step hindle vs. the muzzy pro pipe.

Interesting cam set up. If its mainly a street bike, I would just stick with
what you have. You might even consider playing with the cams a little
but I am an idiot.

My guess would be a small loss of hp on motor but better gains on spray.
Don't know if 1290 is big enough to really take advantage of the pipe on motor.

Post up a question for Rob Muzzy or Doug.
They come around to help us sometimes.

When they "Were" Speaking about it I think the view was the Extra RPM was a "MUST"!! to take advantage of the pipe along with a bigger engine. I think they ised it for one of their bikes and to be fair, made it available to everyone!

The Pro Pipe was developed when there as quite a bit of interest in naturally aspirated development in 12's for ProStar. That has kind of died off and recently Rob did a close out of the remaining Pro Pipes from the production run. They were expensive to produce (merge collector, lots of pieces and welding) and Rob didn't want to do another batch.
Simply put it, as a 4 into one, the pipe lacked some of the nice mid range that a 4-2-1 produces and was built with tube diameters and lengths that were most effective over about 9K. Power contnued to climb beyond the stock rev limit, therefore it was recommended mostly for engines that could rev beyond the 11.8 limit. The main advantage was seen in that last 2000 rpm up to 13,000. We clearly stated that it was NOT recommended for street bikes and that power would actually be less in the middle and bottom.
The extended rev ECU will justify the pipe but be ready for a dip in the middle.

That's how Carpenter gets the high #s. But not the best for acceleration especially for a streetbike. IMHO! I keep telling MrSanta Fe to redegree the cams for a little more in the mids.
