I'm interested in new exhaust for my '00 400ex and I want a full system. I'm very interested in the LRD system because it has gotten good ratings and is priced low. I know it doesn't come with a spark arrester but I was curious if they are available and how much if so. I also would like any other suggestions for exhaust that I could get with a spark arrestor for under $400

Thanks

 

I'll bet if you called LRD, they would be able to make a spark arrestor for that exhaust. I've seen them up close, on their dyno, and they sound and look good.
