The Big Gun Race Series line of exhaust systems are designed for all-out maximum racing performance.
ICC (Internal Ceramic Coating) head, mid-pipe and tail-pipe (value: 1/2 hp lower engine temp, longer engine life). Engine designers and tuners in Formula One, NASCAR and virtually all forms of motorsports know the benefits of aerospace quality ceramic coating on the inside and outside of a performance exhaust system. Ceramic coating allows for hotter exhaust gasses which expand faster, increasing the exhaust gas exit speeds resulting in as much as a 2% increase in horsepower. Big Gun's ceramic coating is applied to the inside and outside of the head pipe, mid pipe and tail pipe.
ECC (External Silver Ceramic Coating) head, mid-pipe and tail-pipe, resists flaking, bluing and rust (value: 1/2 hp lower engine temp, longer engine life).
Standard Race Core produces maximum performance (should be used for closed course competition only).
Works style CNC billet aluminum end cap with USFS approved screen type spark arrestor.
Lightweight head and mid-pipe constructed from the highest grade USA made 18 gauge mild steel.
Performance muffler packing.
New sealed Inlet end cap for a leakless seal (first in the industry).
Pop rivets are all stainless steel blind end so they can't leak or rust.
6 month warranty.

Honda is well known for motorcycles that run great right off the bottom and customers have been afraid to lose this. Wait no longer, Big Gun exhaust systems not only take off priceless weight but also offer more bottom end power to keep up with Honda's tradition.

Honda is well known for motorcycles that run great right off the bottom and customers have been afraid to lose this. Wait no longer, Big Gun exhaust systems not only take off priceless weight but also offer more bottom end power to keep up with Honda's tradition. With a healthy surge right off idle, Big Gun keeps it going all the way through the power curve to keep you ahead of the competition.
The Big Gun Race Series line of exhaust systems are designed for all-out maximum racing performance.
ICC (Internal Ceramic Coating) head, mid-pipe and tail-pipe (value: 1/2 hp lower engine temp, longer engine life). Engine designers and tuners in Formula One, NASCAR and virtually all forms of motorsports know the benefits of aerospace quality ceramic coating on the inside and outside of a performance exhaust system. Ceramic coating allows for hotter exhaust gasses which expand faster, increasing the exhaust gas exit speeds resulting in as much as a 2% increase in horsepower. Big Gun's ceramic coating is applied to the inside and outside of the head pipe, mid pipe and tail pipe.
ECC (External Silver Ceramic Coating) head, mid-pipe and tail-pipe, resists flaking, bluing and rust (value: 1/2 hp lower engine temp, longer engine life).
Standard Race Core produces maximum performance (should be used for closed course competition only).
Works style CNC billet aluminum end cap with USFS approved screen type spark arrestor.
Lightweight head and mid-pipe constructed from the highest grade USA made 18 gauge mild steel.
Performance muffler packing.
New sealed Inlet end cap for a leakless seal (first in the industry).
Pop rivets are all stainless steel blind end so they can't leak or rust.
6 month warranty.

F.I.M. silencers are quiet and have interchangeable end caps to control exhaust flow; one cuts noise to whisper quiet and a straight through at normal sound levels.
F.I.M. silencers are USFS approved.
Factory systems are a straight through design, use a tapered header and mid pipe for incredible horsepower gains.
Factory systems have a new design inlet to clear brake systems when bottoming out.
Titanium Full Systems use a titanium silencer and midpipe with stainless header for longevity.

After enjoying years of racingsuccess in the FIM World Motocross Championship with five-time World Motocross Champion Stefan Everts, Arrow Research & Development built a complete line of off-road pipes. These new exhausts were designed, developed and tested to offer high-performance systems that work well without further engine modifications.
The header and midpipes come in titanium or stainless steel with lengths and shapes optimised for heavy breathing and prodigious power. The silencers distinguish themselves because of their small size, but noise output is minimal due to the use of top-quality sound-absorbing materials. All come with removable spark adjusters.
in order to obtain the best possible performance and reliability, all models were extensively tested in R&D and on racetracks all over the world.Although sold as a single unit, the systems come in three parts: collectors, mid-pipes and silencers. This makes it easier to replace one of the individual parts in the event of a moto no-no. Furthermore, a system made from seperate parts is easier to mount and allows the unit to absorb vibration.
