The Big Gun Evo Racing Series was designed to deliver maximum horsepower and torque gains throughout the RPM range. Made from stainless steel tubing and an aluminum muffler canister, the Evo exhaust system is much lighter than stock units. The sleek muffler design also allows for maximum clearance to avoid your exhaust from hitting the rear brake caliper.

All EVO R Series pipes come in stainless steel with a CNC-machined bracket, Race Tools packing, and spark arrestor screen. No other pipe on the market will come with these included accessories.

  • Lighter than stock exhaust.
  • Massive horsepower and torque gains.
  • Hand TIG welded 304 stainless steel mid pipe / head pipe construction with a brushed finish.
  • Ceramic-coated 18-gauge mild steel stepped or tapered head pipe construction.
  • Sleek silencer design provides maximum clearance which prevents silencer from hitting the brake caliper.
  • Hard anodized 6061 aluminum oval-shaped muffler housing with 'titanium' finish.
  • Slip-fit mid pipe design allows movement of subframes and prevents breaking of muffler brackets.
  • Red anodized 6061 T-6 billet aluminum outlet end cap with removable tip.
  • AMA 96 - 98dB track and trail legal (with Vortex quiet insert, sold separately).
  • U.S.F.S.-approved screen-type removable spark arrestor included.
  • TIG welded reinforced muffler bracket.
  • High-performance Race Tools silencer packing with stainless steel screen.
  • Handmade in the U.S.A.
  • One-year manufacturer's warranty.

The EVO R Series exhaust system has 27 years of Mike Young's - founder of big Gun - personal racing career built into it. Mike has found that having the most horsepower and the lightest exhaust was not always the answer. You truly need an exhaust system that will give you the most tractable horsepower and in most cases a slight weight reduction in the exhaust area can be quite helpful also.

Awesome

No installation instructions but if you are even remotely mechanically inclined it is very simple. Put on my 2011 YFZ450R and immediately noticed a very nice boost in horsepower. This thing sounds amazing as well. Can't speak for its durability yet but all of the TIG welds look very nice and strong.

Good Purchase

Very good exhaust. I bought the complete system for my 09 yfz450r and it was what I was hoping for. I put this on along with a twin air power flow air filter and a wiseco fuel controller. The power gain is great, and the sound is great too. Loud, but good. Easy installation

Got to have

I installed this system on my rapter 700R with a power cammander and a mod quad air filter which I purchased from Motosport, well worth the money. The sound is sweet and the power increase was what I was hoping for, it definately woke my engine up. I didn't give it five stars for installation because there was no instructions, but it was easy to figure out Well if have any ability to work on things you shouldn,t have any problems, but if you don,t your better of staying in front of your computer and finding someone who can help you.

MotoSportExpert
Yes this Big Gun Evo R Complete Exhaust will fit your 2013 Yamaha Raptor 700. Just be sure to correctly select the Year/Make/Model of your ATV before ordering so we can be sure to send you the correct exhaust for your ATV. It would be hard to say which exhaust would be the "best" for you. A good part of picking the best pipe is personal preference riding style, type and conditions. Most of the exhausts are going to have similar performance gains with some having different characteristics over the others. All will have better performance than the stock system. Feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.

Will this be compatible with a 2014 ttr 230 and how do I re jet it ???
MotoSport Staff Expert

MotoSportExpert
Yes. Just be sure to correctly select the Year/Make/Model of your bike before ordering so we can be sure to send you the correct exhaust for your bike. There is not a specific setting I could give you for jetting your bike. It would really depend on your location (altitude/temperature) and how your bike is running with the current jetting. Jetting can be very tricky, there isn't one setting that will work everywhere with every bike. I would recommend taking your bike to a local motorcycle dealership??s service department to have your bike properly jetted. Also, feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.

We do not carry the Barker exhausts and I do not have much feed back or experience with them to tell you if they are good or bad.

The best sound would be completely personal preference. The Big Gun and the GYTR exhaust are both have great performance and quality systems. I would recommend either of them and the power commander 5. Feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.

Will this fit my 2008 honda trx700xx? Should I also be looking at any other mods for optimum performance?
I have a 2008 honda trx700xx stock without any mods so far. But I want to update it with better exhaust, better shocks. I don't know what else I should be doing to jump to a stage 3 or 4 modification class. Can you guide me please? I'm looking for value for money and only the necessary stuff so I don't blow away too much money. Thanks in advance... Habeeb

Is this exhaust designed to handle the 300cc big bore kit for the KLX250s? or will it not really matter?
I will be purchasing a KLX250s in the near future and I'm looking for an exhaust and I'm just wondering since i will be getting the 300cc Big bore kit from Kawasaki for it, Will this affect the performance of the exhaust at all? Or is it not going to make any difference to the way the exhaust works since it is most likely recommended? Also with this exhaust and most likely a K&N air/oil filter, would it be able to handle a stage 2 dynojet? Thanks

The Big Gun Evo R Complete Exhaust will work with the stock and larger bore cylinder on your Kawasaki KLX250S motorcycle. You will have to jet the bike correctly for the modification made on the machine. The Dynojet Stage 1 or 2 jet kit would be highly recommended or other brand of jet kit.

Do I need anything else or can I buy this and put it on my 2004 Honda TRX 450R and be ready to go?

Normally after installing an aftermarket complete exhaust, you will need to re-jet your carburetor. I would recommend getting the JD Jet Kit which will come with jetting instructions. You can find the JD Jet Kit here: http://www.motosport.com/atv/JD-Jetting-Jet-Kit
