Crisp Sound

I bought this exhaust about a month ago, it was a easy install everything matched up perfectly, the first thing I noticed is the exhaust is set a bit flat, which makes it unique which I loved about it. The best thing that I've noticed is it has a aggressive beefy sound to it that is very distinctive and I've fallen quite in love with, it's a very well made exhaust.

Big gun evo R exhaust

I purchased the big gun evo r exhaust full system it was easy to install and I am super happy with it. This exhaust is loud and has a great growl sound to it I run it with no spark arrest or silencer. Once installed my raptor 350 had to jump up to jet sizes on the main and one on the slow, I had my mechanic retune my carb. I noticed an amazing amount of power increase I love it.

Does not fir 2013 honda

This product is not designed for a 2013 Honda 450r WV though moto sport said it was a exact fit... the header and pipe fits but the mounts do not line up with the brackets on the fourwheeler actually one needs to be cut off to be installed once on it is very nice though looks and sound not a fan of the repacking but oh well...

Worth the buy

This exhaust is well worth the buy. It’s on the cheap side for a full system, but that has no effect on performance. This exhaust really opened up the potential power versus that of stock. It bolted up easily and sounds amazing. Would definitely recommend

Big gun evo r slip on for 04 dvx 400

could of went alot smoother. slip on is way bigger than stock head pipe. causing loss of to much air would be nice if they sold the correct fitment for it. after i find fitment it will work like a beats!!

Q: 2012 Kawasaki KLX 250s. I was wondering if there is any noticeable power increase and throttle response for my bike. Also if there are any differences between this and the FMF full exhaust system.

A: The difference should be pretty noticeable when jetted properly. As far as the difference, that's more of a personal preference.

A: Due to there being many factors outside of their control, neither Big Gun nor Yamaha publish horsepower ratings.
After you replace or install each piece, it will be best to have your motorcycle or ATV tested on a Dynamometer to get a specific reading of the changes each piece makes.

Q: Why does this picture of the header pipe look nothing like a xr650l exhaust?

A: Please disregard our photo of the Big Gun Evo R Complete Exhaust. The photo shown may or may not be the unit specific to your motorcycle or ATV.
If you correctly profile your XR650L, including the model year, we will send you the specific unit to precisely fit your Honda.

A: It will absolutely fit. Please enter the year, make and model of your machine into our website to ensure proper fitment. In terms of looks, that is personal preference. Re jetting may be required to get the most of the upgrade.

A: For your dollar, I would suggest sticking with either FMF or Pro Circuit. They both offer different levels of exhausts for your particular bike.

A: The Big Gun EVO R Series is designed using an internal quiet baffling system to keep them between 94 - 96 dB. The exhaust also uses a USFS approved screen type spark arrestor and new end cap.
The HMF Competition Complete Exhaust is intended for race track use only, and HMF offers no claims for the noise limits.
The HMF Competition Complete Exhaust will be louder than the The Big Gun EVO R Series.

A: This will come with the full system but it will not include new mounting hardware or the gaskets. You will reuse the mounting bolts you have and have to purchase the new crush gasket when installing this system.
