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.

Summit RacingSummit Racing Verified Purchase

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.

Honest review

Summit RacingSummit Racing Verified Purchase

SUM-638222
I installed these mufflers on a 383 stroker with 1 5/8 long tube headers and 2.5 inch exhaust ran over the axle and turned down. The mufflers look great. The sound at idle is a bit like a flowmaster and has a higher pitch tone than one when accelerating. It has somewhat of a cackle to it also. Im happpy with the agressive sound. On the highway it is fairly quiet. It sounds like a high end car under heavy acceleration. Everyone that has heard it says it sounds awesome. ...read more

Great value and nice sound

To be honest I bought these as a temporary noise suppression during a new engine break-in, given the low price. But was shocked at how good they sound, and kept them on the car!

Just like the "Big Brand" without the big price!

These mufflers are terrific! They look great, and sound very much like Flowmaster 40 series. Quality of fabrication looks very good, and as usual Summit delivered them with amazing speed. At just over half the price of the big brand, these are another fantastic value!

decent quality

SUM-638222
Very heavy duty muffler, good construction. But if I had to do it over I would have picked a turbo style muffler. This muffler was terribly loud and made it annoying to ride in the car. I had to put in glasspacks to quiet them Down and get rid of that awful high pitch raspy sound. These do sound just like flowmaster 40 series though. Just not for me. ...read more
