    MRD pipes are hand built from 18 gage 304 SS and 6061 aluminum, they are tig welded by hand by owner Dave Harryman. These are not over priced stamped out, mass produced pipes, they have a high quality hand fabricated look. MRD builds their pipes from stainless steel because it is the best material for exhaust systems. SS holds more heat in for better exhaust velocity, it does not dent as easily as Titanium, and it does not require loose spring mounting to keep it from breaking. MRD pipes have superior dimensions and flow better than stock, resulting in noticable power gains. Endcaps are bolted for easy removal when changing inserts or repacking. Highlights: - Tapered design, made from 304 Stainless & 6061 Aluminum - Straight, 2.25" high flow core - Hi temp spec 31 packing - Bolted endcap - 14" muffler section The MRD Z-Pro mod pipe was developed with the help of respected engine builder / tuner Eddie Sisneros of Sisneros Speed Works. This pipe is made from bigger diameter tubing and has a bigger muffler core than the PROCOMP that allows a fully modified DRZ400 engine to develop maximum HP. It can be run with a quiet core insert and spark arrestor and it works great on near-stock engines as well. https://www.youtube.com/watch?v=KoE9LF5MQjk

    Yoshimura RS2

    9 reviews

    DESCRIPTION The Yoshimura RS-2 Stainless Aluminum Exhaust is delivered with a complete kit that includes mounting hardware and well written installation instructions. Yoshimura is well known in the ATV exhaust industry and in my opinion this years RS-2 exhaust system is on par with past stainless and aluminum models made by Yoshimura which just happens to mean they are among the best available for your sport ATV or Quad. Yoshimura ran a dyno test of the RS-2 Full Exhaust System on a 2009 YFZ 450r ATV vs the stock exhaust system and muffler and as you can see the Full Yoshimura RS-2 Stainless Aluminum Exhaust system yields an increase of 2.3 maximum horsepower and 1.6 lbs of torque. The dyno test on the Yosh RS-2 exhaust was run with a 96db sound insert USFS approved spark arrestor but 94db and 99db inserts are also available. Power gains lean towards improved full throttle high RPM response meaning they allow an ATV engine to breathe more freely at top speed.

    DESCRIPTION Staintune Australia has been manufacturing a full exhaust system for the Suzuki DRZ400 since the model was first released. Since then the Staintune system has become “Cult” status with DRZ riders, as it is the best example of “what’s simple works best”. In the first instance the system must be purchased as a full system consisting of a “Big Bore” header and “Hi Flow” muffler. Performance: The full system design allows for a significant power gain when combined with a recommended jetting change for peak performance. There is a 4hp gain “static” on the dyno test over the standard system, however on road test is where real ride ability gains are determined and the DR becomes a very interesting beast. Gains from stop / bottom rpm range through mid range are major, throttle response is snappy, direct and engine uplift is smooth. From mid range through to maximum rpm the engine changes from the standard old plodder to hang on and feel that torque wrap on with the turn of a wrist. Weight Savings: There is an overall 2.5Kg weight saving to be gained by fitting the full system. Finish: The Full System on the DRZ400 consists of a slip joint between the header and muffler connections. This is engineered to never leak and to allow the extremes of flexibility within the DR’s framework so there is never an issue with broken or cracked fixed mounting points. The system is finished in a “bright matt” and really looks good mounted to the bike.

    Material: Aluminum The RS-4 not only increases power and is light, but it also has a lower centralized mass coefficient to provide better handling. The RS-4 is pentagonal shaped muffler that features a carbon fiber cone end cap, two staged stepped baffle and striking good looks. A tapered header pipe design is used for optimal flow and performance. The RS-4 muffler features a new front cap design that functions as a polyresonant chamber. This design makes for a quieter muffler with improved mid to top end power. This Full System comes with a stainless steel header and mid-pipe, aluminum muffler sleeve, installation hardware, and detailed instructions to get you moving! Stainless Systems come with a USFS approved Spark Arrested insert installed in the muffler.

    EXHAUST DESCRIPTION: The Ti-6 Titanium Exhaust System is designed to improve performance and is constructed of titanium throughout the head pipe, mid pipe, and canister while the end-cap is constructed of carbon fiber. Improving power where the Ti-5 showed weak points, and based on customer feedback, a distinctive sound was also created to try and accommodate the current motorcycle rider. Although the Ti-6 will not pass FIM sound requirements seen in professional racing here in the states or in Europe, it is still the ideal system for any rider or racer looking for improved performance, durability and a professional look. In addition to all of these features, the Ti-6 will come with a removable USFS approved spark arrestor making it easy for riders to alternate between off-road and closed course racing. FEATURES INCLUDE: Improves performance Titanium construction throughout head pipe, mid pipe, and canister Carbon fiber end-cap construction Equipped with RC-4 Resonance Chamber to reduce noise output Machined aluminum muffler bracket for increased strength and durability Asymmetrical muffler configuration for increased packing volume Machined mid pipe to head pipe joint for a better, leak free fit Removable USFS approved spark arrestor TIG precision welding Made in the USA
