looking for a mufflre for my FIL's 250 4trax. where can i find a cheap one thats quiet for him with the spark arestor. he claims its neccessary for the dcnr liscense. only thing i've been able to find are artermarket proformance ones for like $300
Good luck with aftermarket. I bought an aftermarket "silent stalker" for my Yamaha. The thing sound like a Harley. I asked around and everyone I talked to said the only way to keep them quiet is with the OEM exhaust.
HMF makes The Swamp series.They claim is slightly louder than stock.The swamp XL is loud hence the XL(xtra loud)This link has a decible chart for stock dbls,Swamp dbls and quiet core dbls. http://www.xopco.com/html/hmfswamp-series.html
