Big Gun ES on 420 Rancher

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

It's loudbut doesn'tshake atvbutyoucanhearitintown

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

Works great!sounds great!

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.

Cool but theres one issue..

(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

Big gun on 420 rancher

I ordered this big gun and got some power changes, not huge but they were good. The hardest part was to remove the stock exhaust other than that no complaints and would recommend anyone to give the eco a try.

Great sound and added power

I loved the sound it's like completely new bike. Don't drive it in the neighborhood if you don't want to get complains about the noise :)

Very easy to install in 5 min.

A: If you can select your exact atv model on the page it should tell you if it fits or not. I tried for you but I don't know your model of atv. If you are unsure then don't buy it

A: I put one on my 2009 trx 250x and didn't do anything with the carb and it seems to run just fine. Although I did turn up my idle but it depends on how yours runs afterwards. If it will fit? Just select your model of atv on the page and it will tell you if they can make it fit or not
