The tests ARE applicable, only exacerbated even more, to the good or bad, since the LS3 makes more hp/tq vs the lesser 4.6. The systems are BOTH true dual, x pipe designs, using exhaust manifolds, almost identical in design, save the piping diameter, which probably is only a 1/4" or so smaller on the mustang. Could that affect sound, sure, will it affect power, sure, but the rankings unlikely, the power numbers will just be higher from a higher hp motor.

Plus, trying to re-create a similar comparison would be nearly impossible, and since this is the best anyone has, comparing this many exhausts, I for one am willing to use it...it has be posted and used numberous times on LS1tech.

I had a flowmaster initially on my LT1 car...it was no where in the same league soundwise as a mustang...the exhaust systems though are TOTALLY different in design, true dual (mustang) vs single-in-dual out f-body (with one cat on my 94'), so the expectation would be different sound. Chevy did a great thing going to the true dual set up on the new SS, it will allow superior flow and superior sound...

For my budget the best compromise of sound and power will likely be in the form of a magnaflow exhaust...usually all stainless design, good flowing mufflers and usually not overly loud, and best of all affordable...$0.02

but the thing to keep in mind is the fact that while they are both true dual exhausts, different size tubing being used, different baffles/chambers being used all have their part to play. a design that works for the mustang might not work for the Camaro.

in a broad sense, yes you can use that test to compare, but until these companies put something on this car and compare them, its not much use. +


and with the single-in dual-out vs true dual, its hard to fight for flowmaster when every other catback manufacturer's exhaust sounded 10 times better on f-body's with the same single-in dual-out design.
