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
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.
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.
Sounds awesome my son loved it on her 700 Raptor!!! Great price and shipping was fast!!
I was a little uneasy getting this over the evo because there weren't many videos out that let you hear the sound of the exhaust but it sounds awesome I'd definitely recommend buying it.
So loud put it on with silencer insert took rite back off rediculousy loud shakes machine and body and ear drums
A LITTLE DISASEMBALY REQUIRED TO INSTALL. CLAMP AT OE PIPE HAS TO BE WATCHED AND ADJUSTED REGULARLY
got it today sounds and looks great! also added lots of power to my grizz.
i bought this exhaust fir my 2006 suzuki ltr and when i went to put it on it didn't fit its about a half in to big in diameter... and i now cant send it back because it got damaged when installing it..
First off this pipe was terrible too install, the header and the pipe never matched up right so I ended up having to do some welding, also the spark arrestor doesn't come assembled from the factory, meaning you have to put the cap and spark arrestor on yourself. Well that's all fine and dandy, but my pipes 3 holes for the end app were both tapped wrong. So I had to RE- tap the holes. After a year of having this pipe (when I am writing this review) the weld on the pipe that connects the pipe to the mounting bracket started to crack and eventually cracked completely. It's a excellent pipe for a temporary install, but please save your money and buy a full system, it will be best in the long run.
Bought this Big Gun ECO Exhaust for a 2015 RMZ450 .
Bolts right up with no problems
Was instructed by BIG GUNS Tech support to add a Bead of high temp silicone to ensure a tight air free seal at the mid-pipe to Header joint .
IT is noticeably louder then stock and Sounds great!!
I bought this for my wife's '12 ltz 400 so I coul
d actually hear bike when were at the dunes.
The new pipe really opened up her 400 over
The stock pipe. I didn't need to reprogram
The ecu as suzuki said the slip on was with
In tolerance. So good sound, performance,
Fit and price.
at first I bought it to make it sound better wasn't really looking for more power but I got it and it sounds great and made a noticeable power difference and no need to rejet from factory jetting
Looks and sounds great on my 08 trx450er.easy installation and a great price
took 15 min to install, woke up the motor, loud for the track need to purchase slincer with it.
I purchased for a 2013 RZR800S LE. Fit and finish are perfect once I got a new oem exhaust gasket. Sounds great, looks even better. Be sure to order a new oem exhaust gasket. Takes a little finesse to get on but makes the system fit. Almost impossible to get old gasket off without destroying it. Also I recommend getting a spring puller, makes the install easier without having to take apart the entire rear of the RZR.
