The PowerBomb header promotes better flow by allowing a small expansion of the exhaust gasses. The 'bomb' also acts as a pre-muffler taking the edge off of overall sound levels.

Optional Heat Shield Strip will protect your airbox from the close proximity of the hot head pipe.

Our very own high flowing head-pipe is made in the USA using a CNC (computer numerically controlled) mandrel bender for an absolute perfect fit. It is a high quality 3-piece welded two into one, stainless steel head-pipe.

• Primary tubes: 1-1/4" diameter
• Collector tube: 1-3/4" diameter

The SS Pro-Flow is a tested upgrade over stock that will bolt right on with no modifications needed.

The DG RST (Reduced Sound Technology) muffler is the quietest DG muffler and is designed especially for dual-sport machines (Just 89db @ 3200 RPM). A new baffle design dissipates sound waves reducing noise output in a very efficient manner. This new design also stretches out the time between muffler repacks. Included is a Stainless Steel mid-pipe, USFS Approved Spark Arrestor and a new Aluminum end cap.

You may want to consider a new exhaust gasket that goes between the header and the muffler.

Body is made from lightweight 6061 T-6 brushed aluminum and the end cap and intake tube are stainless steel. Silencers include wire-meshed spark arrester that can be removed for closed-course racing. Optional end caps allow fine-tuning of power delivery for different types of riding and terrain.

The RS-2 is a potent and versatile design that evolved from our original TRC, engineered to provide increased power and power delivery. With a different pyramidal shape that features increased volume, the RS-2 is a quieter system with a larger core - and it offers the added bonus of outstanding performance in a value-priced package.
