06 WR450 Exhaust

8 posts in this topic

Hey,

What's the best header and pipe combination to run on the 06 WR450? I assume you must re jet after adding a pipe. Last, is it a considerable difference after the jetting and the pipe? Thanks for any advice.

Since you are in California, I guess you have to stick to the quiet pipes.

Most people around here prefer the FMF Q2 slip-on. The header is fine.

Good question vavoom!

There are a couple of threads already on this - read and you may be quite confused??? or enlightened!!!

I just got a 06 and the I am pretty sure all 05 listed mufflers will fit although most parts catalogs only list up to 05 - they have not caught up yet. (can any one substatiate this?)

Like Matty05, I thing you will be best served by a Q2 (for noise). I am not sure of the need for a header but I believe a good combination is the SX power bomb header which appraently reduces noise as well as assisting power.

There is plenty of testament that the standard header is fine - just put a (any) decent end can and away you go.

06 WR - good choice.

Cheers

Another good one is the PRO-TEC MACH 1. It has an Adjustable Noise Supression available. It allows you to tune the noise and power with out removing any parts. For those of us in Kalifornia, the adjustable noise supression is nice to have. They have a jet kit for the wr450 tuned for the pipe and some testing results on their website:

Thanks for the replies. I can't wait to get back out in the dirt....hopefully with a new pipe/jetting.

Vavoom,

Just spend $60.00 and buy a PMB insert, swap it out for the factory pea shooter, do the free mods and you are good to go. The WR has more power than most of us mere mortals can use. You don't NEED a bunch of noise too!!!!!!!!!!!!!!!!!!!!!!

so to clarify....

you left the stock spark arrestor in the pipe and bolted on a noise suppressor?

I ask b/c on their www site, the only 60$ is a silencer only (bolt on)

thanks, ken :thumbsup:

Yes, it's REALLY easy and fast and you leave in the stock spark arrestor. If you live in SoCal, heck you can try mine out since I just bought a new muffler. Just let me know.
