...Well, just bought a brand new "Big Gun" complete exhaust system online for $300. Anyway, the part number for the kit is 10Y-435, I need to know if this will be quiet enough for USFS land and if it has a spark arrestor. Anyone else have this system and how do you like it? Is it reasonably quiet? I have a 01 WR426FN and it has the stock exhaust system on it now. I hope this will improve power without making it obnoxiuos. I see these retail for well over 400 and up, did I do OK on price?
