Pro-choice T-4 Head pipe

It's a very well-made product, durable, expensive and three weeks on backorder; but definitely worth waiting for. Moto Sport came through the fastest of any other online retailer and a dollar cheaper, too♤

T-4 head pipe

Got one of these for on my crf450r dirtbike, because the stock titanium pipe is absolute junk, first time you lay the bike over the stock one is bent or crushed. This pipe is very strong, the stainless is way better and is only a touch heavier. Its pricy for just a headpipe but no other company makes this to mount to the stock silencer I have heard. Another thing is that there are no mounts for the pipe guard, but when the pipe is strong like this one, maybe its not necessary? Overall good product

Real power enhancement?
"This is a stock replacement head pipe" This is what is written on the description; it means that it has the same diameters and same shapes of the OEM pipes? If it's so, has no improvement, right? It should be possible to have a "real" pictures of the part? Does it come with the midpipe?

All Pro Circuit head pipes are designed to work with stock (OEM) or Pro Circuit mufflers so fitment can not be guaranteed with your Yoshimura slip-on.

Replacing the head pipe only will not have much if any effect on the sound.

Yes, Pro Circuit says their headers will work with the stock OEM silencer or any Pro Circuit Slip-On Silencer making it the perfect choice for upgrading your stock system. This is for Pro Circuit headers only. If you choose a different manufacturer, fitment to your stock (OEM) silencer is not guaranteed.

Will this header work with my Ti-4R?
I have a 2010 CRF450R with a Ti-4R full system. Will this header fit my Ti muffler? Pro Circuit wants $300 for the header alone

This will only work with the OEM Muffler or a Pro Circuit Slip-on Muffler. Unfortunately it would not work with a Pro Circuit full system as they use different mid-pipes and headers that the slip-on exhausts. I believe you will have to get that replacement header directly from Pro Circuit.
