Yamaha Wolverine X2 / X4 Big Gun EXO Exhaust

I'd like to first say that if you're looking at getting this exhaust, do not judge the sound off of Big Guns youtube video on the X4. The exhaust is quite a bit louder than the video depicts especially with the spark arrestor out. Cruising isn't bad at all to me but definitely screams when you hammer it. Also if you put the spark arrestor in you'll want a thicker spacer ring for a tighter fit otherwise it rattles the whole time and is very annoying. Having said all of this, I CAN'T WIPE THE GRIN OFF MY FACE. I never thought such a mean sound could come out of a little twin cylinder. Not to mention it looks beautiful. I bought this with the Dynojet tuner that I'll write a review on and added WR's tuning with it and the combination is fantastic! And as always Weller Racings customer service is second to none. They even called me to tell me the exhaust would take a little longer to ship than the rest of my order. Highly recommend this exhaust to anyone that doesn't mind trading quietness for performance!
