I have a 2000 WR400 that I bought used with an aftermarket exhaust system. I can't figure out which manufacturer made it.
The headpipe, midpipe, and muffler look aftermarket. The muffler is tack welded onto the midpipe and there are provisions for springs at each union. The muffler is extremely loud (sounds like a straight pipe).
I'm trying to add a spark arrestor to the endcap of my muffler. Can anyone help me identify who made any of these parts?
Note: I tried to get forest legal by changing to a White Brothers slip on exhaust system (with spark arrestor) that I bought used from someone with a WR426. When I tried mount the white brothers system, my aftermarket headpipe was too short, and I was left with a gap. All the joints between the headpipe, midpipe, and muffler are located at different points when compared to a stock setup.
