Thing bolts right up. Literally 10 min project! Looks great and sounds better. Every sport quad needs exhaust.
Mean sounding and loud. Neighbors didn’t like it but I did!
bought this slip on for my yfz 450r se. amazing sound and easy to install. great product for the price!
The power it adds to my Z400 is amazing but what I really like is the sound that it makes !!! just makes you feel like you can get after it !!!
You know the old saying you can't get down if you don't hear the sound!!!!
Seriously this is an awesome product I am very very pleased with it!! it's added lot to my Suzuki Z400!! it was an awesome wheeler before now it's a totally awesome digger !!! I love what this has added to my machine Power and Sound and I've got So many compliments on it it's pretty cool !!!
Wayze to install takes less than 5 minutes highly recommend the BIG GUN !!!!
I bought these big gun for my 420, and saw very little power increase even with the optimizer. Before the optimizer my bike WAS Lean with just the exhaust and I am around 150 about sea level if that helps you any with the air pressures and whatnot. It was ehhh to put on the first time, but I did remove it and put it back on with ease
This atv exhaust is loud but I don't think man that it shake your quad because it's not shaking my atv it's loud enough that you can hear it in town on the other side in town other than that it's sounds like a raptor without a baffle in
Me and my dad put ours on my honda rancher 420 es and it went on like a dream the only hard part was taking the stock off. My fourwheeler only use to do barley 50 now can do about 61mph
Sounds great.looks great.motosport service was excellent.had trouble getting it to seal to header pipe.clamp broke trying to get it to seal.big gun sent me new clamps but still wouldn't seal.had to buy heavy duty clamp for a motorcycle slip on pipes and finally it sealed.but all around happy with it and also happy with service from moto sport and big gun.
(2009 Honda trx250x) got this during the summer and it sounded great but then the gasket between the slip on and header kept popping out. one time it came out in the middle of WV trails at hatfield mccoy, I had no choice but to keep going. the gasket eventually blew out the spark arrestor. So after all of that, I decided to make another notch at the end of slip on so that the clamp can squeeze down harder for a tighter seal. Last night finally I put some jb weld around the gasket (3rd gasket i have bought for this one issue) to prevent it from coming out. Tonight i'm going to put on the slip on and clamp it and hope it works. if not i'm gonna need a better clamp or something. Just wish I didn't have to do all of this un-legit stuff to get it to work but oh well
