Flowmaster vs. Magnaflow on a C3 Corvette
sound impressions at idle engine speed of two different mufflers mounted to a 454 72 Corvette. Just to make sure: The Flowmaster 42551 ist the one at the passenger side. The Magnaflow type 323416 is on the drivers side. Note: at 1500 rpm the sound pressure of the flowmaster is 6 dba louder. 92db vs 98 db !! Now ,after driving about 500 miles with the magnaflows I must say that the former flowmaster sound was much better because it was way deeper with much more rumble. ! But: the Magnaflows look like bone stock.
1992 Camaro RS L98 350 TPI Magnaflow 16829 Cat-Back Exhaust
Got bored so I figured I'd make a clip of my new Exhaust. The car is pretty much stock aside from the cat-back, meaning stock y-pipe, dual cats, and Exhaust manifolds. The Exhaust is a magnaflow 3" cat-back with a turbo style muffler. The car was running for about 20 minutes right before I made this video so this isn't a cold start.
