Big Gun Oversized Header & Silencer For Sale

This system is on a 2000 WR 400 and really gave the mid and top especially good results, but none on the bottom. The distributor in Canada sold this to me as a mistake and now out of business. I was looking for the SDS system. I am selling to get what I wanted originally. Mint condition with 450 miles on it. $180 for complete system. E-mail at


An easy, inexpensive solution - puchase the SDS header pipe from It will fit your exisiting BigGun tailpipe/silencer.

Rockymountain ATV/Motorcycle is great place to mail order from, great prices and great service.
