Cool pipe

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.

Big Gun Eco System Slip-On Exhaust for RZR 800

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.

Do I need to rejet after installing this on my 400ex?
MotoSport Staff Expert

Normally when installing a slip-on only minor jetting changes are needed, if any at all. If your bike is currently jetted properly you will likely not have to make any changes after installing this slip-on. I would recommend installing the exhaust and riding the bike to see how it is running then tuning your carburetor from there if necessary.

Generally, most utilize the stock gasket. Refer to Big Gun instructions included with the exhaust.

Normally when installing a slip-on only minor changes to the air/fuel ratio are needed, if any at all. If your bike is currently running properly, likely you will not have to make any changes after installing this slip-on. I would recommend installing the exhaust and riding the machine to see how it is running then decide if you need an purchase an aftermarket EFI tuner .

My stock gasket doesn't fit. It's to big.?
I have a 2014 YFZ 450R and my header pipe fits in the muffler pipe but I can't use the gasket. It won't slide into the muffler pipe. Any ideas??

Many aftermarket exhaust use a friction fit at the midpipe to the header pipe. They do NOT use the stock gasket there.

Will this exsjuast fit on a megabomb header by fmf?
Expert MotoSport Staff
Over 7 months ago
MotoSportExpert
FMF headers whether it be the PowerBomb or the MegaBomb, are fitted to match an FMF series muffler. FMF does not recommend or guarantee you try to match it to another brand or OEM. You will want to find someone that has hands on experience pairing an FMF header with a Big Gun Slip-On for your bike to know for sure.

Yes it will run great with a aftermarket air filter no problems I have a moose air filter. Add a small noticeable amount of power, try taking your airbox off to add more power. Yes it comes with everything needed for instillation. Add"s 3-6 horsepower depending on your atv
