The DR. D slip on exhaust is birthed from Doug Dubach, who brings years of experience to the motocross and supercross scene. DR. D constructed this slip on system with an aluminum muffler in conjunction with a magnesium end cap to reduce weight and provide long lasting durability. To create a solid mounting point DR. D uses a CNC billet hanger on the extruded aluminum muffler sleeve. The magnesium end cap on the DR. D slip on exhaust system is easily removable to access the spark arrestor screen. With the spark arrestor installed the exhaust system meets USFS approval. Repacking the DR. D aluminum muffler is simple with the removable bolts on the lower end of the sleeve. The DR. D complete Slip On includes: aluminum muffler and USFS approved spark arrestor.
The quiet core insert can be used with any DRD SA muffler. The CRF150 does require a different insert. The insert can be installed and removed very quickly. And as the name suggests it significantly reduces the sound level. Although you will experience a mellowing of the power by installing the insert there is not a significant power loss. Will not fit the new NS-4 exhaust.
LRD Performance developed the Pro 4 Series slip on exhaust to provide exactly what the brand says, performance. LRD engineered the Pro 4 Series slip on exhaust to provide the best acceleration your quad can handle and increased power over the entire power band. Other exhaust manufactures focus on giving maximum power, but when your ATV cannot get off the line or come out of the corner as fast it is pointless power. The Pro 4 exhaust was also designed to improve throttle response. Stainless steel construction on the Pro 4 Series slip on exhaust gives substantial increase in durability without adding weight. A bolt on billet end cap makes it easy to perform maintenance on the Pro 4 exhaust. LRD includes a USFS approved spark arrestor with the Pro 4 Series slip on exhaust. The Pro 4 Series slip on exhaust weighs in at 4.8 lbs.

As the pioneer of quiet performance mufflers, FMF raised the bar again in 2007 with the second generation of Q series mufflers, the Q4. Built from the ground up, the Q4 is a completely new design, engineered for maximum performance while maintaining a sound level at or near 93 dB on most models. The Q4 is the market leader for low sound / high performance. Less sound equals more ground. Q4 Details: The Q4 incorporates Factory Forward Engineering to move the muffler closer - centralizing the mass for improved handling characteristics. The new Hi-Flo formed end cap reduces weight and is less prone to damage. The Q4 has an anodized aluminum canister and is lighter and quieter than the original Q model slip-on. All Q4 exhausts utilize a maintenance-free USFS-approved turbine type spark arrestor so there is no screen to clean or burn out. The Q4 employs free-flowing internal baffles and chambers, advanced sound-absorbing materials and a reduced weight. Max Sound output 96 dB, most models below 93 dB. Constructed from aircraft-grade aluminum and high-strength stainless steel. Use with stock or FMF header.
