These mufflers will offer the same performance benefits as the more aggressive mufflers, but they will also control the overall sound level better.ĭo you want to hear the muffler all the time, or just when accelerating? These mufflers will help control the interior sound level better than the aggressive mufflers during long drives or when towing a trailer.

Smaller displacement engines will sound less high pitched and buzzy when a more moderate or mild muffler is used.įor daily drivers and vehicles used for towing, we typically recommend a moderate or mild muffler. On large displacement and high horsepower engines, larger mufflers will control sound better. Vehicles with large cabin areas like SUVs or hatchbacks can be more susceptible to interior sound, or drone, when an aggressive muffler is chosen.Įngine size and power output have a big effect on the sound level. Check the area where you will be mounting the muffler first to make sure you have enough room for the muffler you decide to go with. The chassis type and layout of the vehicle can limit the choices you have in mufflers.
What type of vehicle are you choosing a muffler for?

Please have a professional exhaust or muffler shop help with the installation.When selecting a muffler there are a few things you should take into consideration. vehicle fitment is very tight because of the lack of space.
Winner of the 2007 Ridler Award, Troy Trepanier of Rad Rides by Troy!. 409S outer shell, and 409S internal construction. Can be placed in virtually any location under the vehicle. This convergence of sound waves reduces the sound level as it passes out of the muffler. The carefully selected taper angle of the exit cone directs and focuses the sound energy back into itself. The increased surface area and angle of the tapered exit cone provides an "easy exit" for the hot exhaust gases that encourages the flow out of the muffler. This thermal barrier is engineered to deliver much lower exterior case temperatures, allowing the muffler to be placed closer to heat sensitive areas The thermal barrier between the outer core section and muffler case provides a portion of the mufflers sound energy absorption characteristics. Sound waves lose energy in this section through the expansion of the exhaust gases and reflective angles of the cones which direct the waves into the thermal barrier material. This produces a controlled laminar flow pattern, that reduces turbulence inside the muffler. The hot exhaust gases are released and allowed to expand into this section in multiple layers due to the tapered angle of the entry cone. The perforation pattern and entry angle are specifically engineered into each product to provide optimum airflow characteristics.The sound energy is reflected and redirected back into itself as well as into the outer thermal core by the carefully selected taper angle of the entry cone. Hot exhaust gases entering the tapered inlet section are actually accelerated as they pass through the perforated cone into the outer core area. The HP-2 line offers a wide variety of applications from rock crawling to award winning customs. 2.50-inch inlet/outlet diameters, there is a model available to suit your needs. 
The 409S HP-2 mufflers feature a painted 409S outer shell, and 409S internal construction. Due to their Cool Shell Technology they can be placed in virtually any location under the vehicle. The 409S HP-2 mufflers have a case length of 18-inches and a 4.00 X 5.50-inch width.
