Not good fitment

Nice quality,nice sound but not very good fitment. Header pipe was way to close to the carburetor on the crf100 so had to bend it. I do not think it would work if you had a larger carb.

Bad as's

Excellent performance pipe!

Bought this pipe for my 2002 xr100. It looks better and I think performs better than my friend's FMF on his xr100. Way better than stock and sounds throaty. Doesn't offer a way to use stock heat shield, but so far no issue as the pipe is tucked in nicely. this is my second Big Gun exhaust. Completely satisfied!

Big sound for a little bike

I bought the Big Gun Evo M because the other 110s in our stable have pro circuit t4 & t4i & I wanted something different. It's very deep & throaty off the bottom, does not one bit sound like a 110 anymore, more like a 250. The pro circuits are nice & loud but even my brothers like the way the big gun sounds better. It's just got that deep, big bike grunt to it that the pro circuit pipe does not. I never get tired of hearing it. OEM pipe was about pinky finger diameter @ the head, big gun evo m is closer to a thumb! After a rejet & airbox eliminator my klx 110 pulled like a whole new bike. The change in power delivery was crazy, I went from barely able to get it to wheelie to riding them up & down the street with ease. Cool that it comes with an optional easy install spark arrestor too.

KLX 110 with Big Gun

My son wanted a louder exhaust on his KLX 110 and I decided to go with Big Gun since I had seen and heard them before. Now the KLX 110 sounds like a 450 rumbling around the track and through the woods, it is awesome. People that ride where we ride have made comments about how it sounds like a 450. Bottom line is, Big Gun rocks.

Fit great, sounded better!

Installed on my sons klx110...gave it a deep great sound! Only difference there is no way to attach the factory heat shield without finding a way to modify.

Second choice, great choice

Wanted the TBR M8 exhaust but was on back order. Went for this guy and am thoroughly impressed. It's loud and adds power to my 2015 klx110L. Wish I could run it without the spark arrester more!!

Sweet buy

sounds sweet and makes power

A: The Big Gun Evo Mini Complete Exhaust would be ready to go. I do recommend usually replacing the exhaust gasket at the head, but it is not always necessary.

Q: Will this fit a CRF80F

Is this thing loud, I want the loudest one on this site.
MotoSport Staff Expert
Over 3 years ago
A: The big gun exhaust is one of the loudest exhausts for the mini's. I have ran the Big Gun exhaust on some of my pit bikes (XR50/XR70) and would say this would probably be the loudest for your CRF80F.
Q: For a 2002 xr 100 does it come with the same end cap as in the picture?
Over 3 years ago
And is the end cap removeable?
Expert MotoSport Staff

A: Yes, the Big Gun Evo Mini Complete Exhaust has a Red powder coated stainless steel end tip. New euro end cap like the larger Big Gun exhaust systems to give the total factory look.
