| Using Edelbrock's patent-pending Sound Deflection Technology, these high-flowing
mufflers are the latest in exhaust equipment. The chambered design manipulates the sound waves while allowing the engine
to breathe. The benefit is a distinctive and throaty exhaust note that's dripping with muscle
without going over the top. The SDT Muffler is completely free from any packing material, eliminating
blowouts and deterioration of the sound over time due to wear and tear.
The Edelbrock engineers met the audacious challenge of developing a chambered muffler that would
achieve the right balance of sound and performance. Their solution—use the sound against itself. As the
exhaust enters the muffler, the sound travels through the entry chamber and into the resonator chamber
where it's reflected back out into itself, lowering the sound level. The exhaust then passes from the entry
chamber and into the parabolic sound deflection chamber via an intermediate tube. Inside, the parabolic
sound deflectors are designed so that the incoming sound wave energy is redirected back upon the
incoming sound waves, reducing exhaust noise significantly. The end result is a powerful and throaty
sound that produces more horsepower than the most popular chambered mufflers on the market. |

Now Available in Two Styles
Two styles of SDT mufflers are available from Edelbrock to fit a variety of applications. Our Ti-Tech SDT
mufflers are built from 14-gauge aluminized steel and finished with new Ti-Tech coating that maintains its
good looks even after hours of use in harsh conditions. Read about Ti-Tech or Ceramic Coating for more details on this exciting new
finish. For a show winning looks with SDT performance, our 304 Stainless SDT mufflers are constructed
from 304 stainless steel that can be polished to a high luster. |
