Im looking for a loud and a deep tone sound at idle and acceleration for my SBC 350. Would you recommend this muffler for what Im looking for?

Asked by PATRICK on April 20, 2019


Thank you for your question. The Summit 638222 2-chambered performance muffler has the sound characteristics of a chambered muffler. The tone of an exhaust is dependant on engine size and RPM and cam profile. This particular muffler has been known to sound good with a mild small block Chevrolet.

What is the difference between these 2 chamber muffs and the 2 chamber race muffs ?? (besides $6)

Asked by JOHN on May 21, 2017


Thank you for your question. The Summit Racing SUM-638222 performance mufflers are designed for street applications where a more aggressive sound and decreased backpressure is required. The less restrictive two-chamber race mufflers are designed for both off-road and race applications that require maximum flow.
