There was a joke about my truck having "world ending" exhaust when I had my Spintech. It does sound amazing. It's sounds completely different from anything else. Flowmaster 10s sound like garbage compared to a Spintech.

it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
FYI ive done dyno testing of a spintech setup and it sure chokes it up vs a straight thru muffler....wouldnt catch me using a spintech

he said super 10 series, which are a garbage cheapy one chambered muffler that doesn't flow worth a crap....much like the spintech mufflers
had a buddy go from a spintech to an ultraflow and picked up 6mph...that's a ton of hp.

well, it's in a thirdgen camaro, so not sure that 6mph is 60rwhp since it's not a 5000 pound tank

Still not believable.....
you don't have to believe it. he did it, and i saw all the data from before and after. only thing i don't think we took into account was DA. but you're not going to pick up 9mph going from a terrible air quality day to a great air quality day...even in GA where you can have 4000' DA in the summer, and -1000' DA in the fall/spring.
anyway, chambered mufflers are not performance mufflers. i picked up 2 mph going from a moroso spiral race muffler(chambered) to a dynomax bullet(straight through) on my car.
maybe i need 6000+ posts before i can add to conversation around here and be taken seriously
