What do you guys think about the '06 header w/customized 09 muffler?

I think it would be too loud. Cute, but too loud.

Dont know about everyone else but mines probably going to end up on my lawnmower or something. Too bad, I liked the look of the shorty.

I do have a little project in the works, but don't look for it very soon. Low priority.

Well I sold my 04 with a WB stainless header on it and kept the stocker and I bashed my header on my 08 sooo I put the stock 04 header on and it seemed to boost the bottom end. I was surprised it fit too.

When I bought my LeoVince slip-on it came with a smaller/thinner header gasket that fit perfectly with the 04 header. Where as the 08 header had no gasket so now I have less of a chance at a exhaust leak.

I'll buy you a muffler for your mwer in exchange for your 08 muffler.:thumbsup:

I have an 08 header and muffler. I'm thinking of doing this and i will take whatever praise/criticism comes with it. My header is somewhat dinged up and not pretty, however, i just got dont bead blasting the whole bit and inclined to do a header wrap for the look of it. I know that titanium has a tendency to crack in this scenario, but would like input/opinions on it. I am gonna run the stock can (at least for a minute) and see how this does. I want to buy a FMF 4.1 USFS can if the 08 can cannot be sufficiently modified with my

I just got my endo in and installed it. Do you think its bad for the bike to not run the cone or sparky, just open?

I was just about to wrap my header in the area of the shock reservoir. I'm trying to keep shock oil from getting hot or as hot. Is this a bad idea, to wrap titanium?

I run mine open with no issues (other than a nice power boost :thumbsup:). My bike is re-jetted though.

It's not a big deal, but it won't keep the shock any cooler. The shock oil gets hot because that's what shock oil does. The exhaust runs past the reservoir cap, which has no oil directly under it. Then, you're expecting heat to radiate across an air gap through which air is usually moving. If you aren't melting your air box or number plate, you aren't contributing anything significant to the shock oil heat.

I was thinking more about the heat from the pipe when lined up at the gate. I thought maybe it would help alittle bit or am I just getting alittle crazy?:ride:

Also, do you think the 06 header w/PMB Endcap would focus more towards increasing low end boost with some (small) increases at mid-high due to size and length of header? Or do I have to stop thinking?:thumbsup:

In the strictest sense, it will "help a little", but I don't think you fully understand how long it would take to raise the temperature of your shock oil 5 degrees by having a 500 degree pipe at that location. A little crazy, yes. Try to worry more about the next election.

If you modify the shorty muffler to be more open, the diameter of the '08 header will be too large to be optimally effective, and the '06 would be an improvement.

Don't stop thinking, just don't stop thinking all the way through, either.

Hey Gray, you seem to be the yz guru so, maybe you can guide me in the right direction. I would like to know where I can find out the dimensions of stock headers that are compatiable with the 09? Thanks for all your help, I appreciate it.

The resident wiz on that particular subject is KJ790. He's gone through this several times, but I never pay enough attention to remember it. Search for posts re: headers by him.

I think I remember that the '06 header is a direct fit, but don't quote me.

The header off my 04 bolted right up to my 08(same as 09) with just a thinner donut gasket.
