Goo sound

Very loud and you will need a tuner I have a 2019 yfz450r se and it back fires a lot and is very boggy and lower cruising rpms so you will need to purchase a tuner as well

Got what I was looking for!

Got the exhaust a week ago, installed it on my 2018 raptor, along with the k&n air filter conversion. This exhaust not only looks and sounds great, but adds a very noticeable power increase, it breathes fire! When I say it breathes fire it really does, the intake and exhaust changes were so great that it leaned my bike out, and at idle the manifold gets hot enough and glows enough to light a dark garage! Lol. With all this said make sure if you purchase these 2 products purchase a 3rd, and get the fuel management system along with it., and you will unleash mad power!

Poor instructions

Bought the slip on exhaust as my other exhaust for my TRX250EX had rotted-out. Bought it and open the package to discover that it did not come with any gaskets and I had to order another OEM gasket from Honda which is going to take an additional week after finally getting the gasket in the mail I go to bolt it all on and the exhaust clamp that big gun send me does not tighten down enough to hold the slip on pipe to the header pipe needless to say I am super frustrated and probably will be returning the slip on exhaust and buying a full system super super frustrated and very unhappy

Love the sound

A few months ago I got 2016 Yamaha raptor 700rse and it still had the stock pipe on it and it was holding the bike back so I purchased this and put it on and the bike runs and sounds so much better

I bought this exhaust for my YFZ450, and I absolutely love it! Be aware though, it is insanely loud. If you want to go to the track with it, you will need a quiet core. It DEFINITELY increases horsepower, and just wakes YFZ's up. Overall a amazing product.

It's so loud a cop might pull you overforloudnoise

This is a exhaust I been wanting but I haven't got it but I heard it's been very loud exhaust so if I ever get it I'm keeping it loud because I drive everywhere on the road and I want a car knowing if I'm coming down a street you'll probably hear this scream on the other side in town

Yamaha raptor 700

I put the big gun exhaust on my 2016 Yamaha raptor, lol it's so loud and so much more aggressive when I hit the throttle, it's sounds like the hells angels are coming when I'm ripping around, so I love this big gun exhaust, also I installed a big gun evo on my sons Honda 400x atv and that sounds amazing also and great throttle response we are very happy

A: All of the after-market mufflers are louder than the original from Honda. Our Big Gun Evo Race Slip-On Exhaust is available for your 2002 Honda TRX400EX.
Because the Big Gun Evo Race Slip-On Exhaust is specifically for racing, it is quite loud, and also helps to produce more horsepower. Any of the race mufflers are louder than the street-legal or the "Q" style Quiet mufflers.
