SpinTech : 3442 : Sportsman Street Muffler - Inlet: 3 Inch Center - Outlet: 3 Inch Side

Our Sportsman Series was originally designed as a racing muffler - it was too quiet, so we turned it into our premiere street mufflers.
  • Case size: 4 X 8 1/2 X 13
  • Traditional muffler designs remove sound in two ways: friction and absorption.Friction mufflers (stock type, turbo type, chambered) have high back pressure and can cause extremely high resonance and noise inside the vehicle at certain engine speeds (2000 to 3000) RPM.Absorption (packed mufflers) have a straight through design, they can have good flow but the packing begins to deteriorate and get louder as they wear out, and with modern engines the heat is very high which destroys the packing even quicker.
  • SpinTech's patented design provides maximum performance for today's modern engines. Its all done by means of a Spin sound trap, which captures sound vibration (noise) and turns it into heat within the muffler case. As exhaust gases enter they are routed to the spin traps which create a high velocity vortex trapping the sound waves. The extremely high flow rates are achieved by a unique internal scavenging system that creates a venturi effect.
  • SpinTech mufflers are about as close to bullet proof as a muffler can get. With a 16 gauge fabricated shell and welded construction, you'll be hard pressed to do them much damage. The nice thing about 16 gauge steel - you can weld, and repair it, should either become necessary. Try that with a $19.95 special!
  • Spintech mufflers get their name from the unique scroll-shaped sound traps welded into the muffler case. They mute objectionable sound waves without inducing unnecessary backpressure
  • Oversize freight Charge of $10 to be added at time of shipment
