Q:

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

A:

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.

Q:

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

Asked by JOHN on May 21, 2017

A:

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.

Better than Any Flowmasters and Turbos I've owned.

Unbelievable Great product for the price compared to Flowmaster's price. I used these to replace a Set of Flowmasters on a 1978 Corvette with true duels exhaust. Deep sound and good choppy note with my 3/4 race cam. Does not resonate or give you that Tone headache you get from Flowmaster. Awesome and will by more for my 70 Charger.

Loud.

This is a FM40 style muffler and it is loud but it sounds pretty good. The painted finish on the muffler was a surprise and should help it survive a little longer. Plus it looks good. On my 350 second gen Camaro, it drones with tailpipes but not with dumps. Your results may vary.
