2013 wr450f exhaust

so i picked up a new bike the other day, and after un restricting it all up and pulling the little baffles out of the exhaust i still think it sounds a little wimpy. is there any other mods i can do to the stock muffler to open it up? i have also been looking into a slip on exhaust but am not a big fan of how long all of theyre mufflers are. so my second question would be will a slip on for another bike fit? say maybe for a yz450F?

I just bought a 2012 and installed the GYT-R PC4 and PB header....looks pretty good IMHO. Sticks out a bit but not obnoxiously so. Sound is reasonable with the QC insert.

I think part of the issue is the new number plates, they are shorter than the older bikes plates.

do you have any pictures?

Nope, Not yet

do you have any pictures?

Is this the picture you're looking for? I don't think the FMF exhaust sticks out too far... and I don't see what it would bother anyway? Do the pipe, it makes a big difference in performance and sound.

BoiseBee: how many hours do you have on that beast? yours looks a lot cleaner and less beat up than mine. I'm going to have to invest some cash in new plastics this summer, that's the off-season in AZ.

To the OP: I remember reading posts in this forum about people successfully installing exhausts from older wr450s and 06-09 yz450s. You'd have to dig through the "2012 wr450f" topic to find them.

Yeah, mine still looks like new..... sitting at 333 miles. I had it up at the cabin all summer/fall and we had a 100,000+ acre fire break out and burn 100% of the trails that I had direct access to. Over Labor Day I trailered it to a riding area on the other side of the highway from the burn and the Forest Service still had all those trails closed.

I brought her back to town for the winter and tore her apart for some aftermarket goodies to get ready for spring. Yesterday it was 4 degrees outside, so I'm probably looking at February before I get some throttle therapy.

Yes that picture is what I was looking for! The sticking out is more of just a visual preference than a problem, and I'm assuming its on wrs to meet green sticker requirements which led to my curiosity if anyone's had any luck putting exhaust from a yz on a wr. And also does changing the head pipe make any noticable difference in power?

The header is a factory power bomb to improve mid range because of the swap to EFI.. IMO it's not needed. The muffler is the same length as yz mufflers as far as I know, it's just the design of the body that makes it stick out.
