Yea I have my cats gutted also. No headers just yet, they will come soon. I looked at the youtube of some spintech videos they look pretty good. Be a hard choice i guess

Iv had both in various versions. Trust me the spin tech is way nastier and louder..
Slowest in Oklahoma...
I like the gentle growl of a big body magnaflow followed by it screaming at wot.
ECSB 2kSierra 2wd 4.8L-K&N-HPtuners-Calspeed LT's-Magnaflow-Tahoe20's-HankookRH06
waiting to go in... 3.90s, 214/220cam
Agreed. I didn't run the spin techs long. Sounded good. But to loud for me

flowmasters are loud, drone, and don't flow that well. a quality straight through muffler like a dynomax ultraflow or magnaflow will run circles around a flowmaster, and the wrapped perforated tube design really resists droning like a chambered muffler does. my single 3" magnaflow is very mild under normal driving loads and screams at WOT, and has such a smooth refined tone.
2000 ECSB Silverado 2wd 5.3/4l60e. basically stock
1990 Camaro 5.3/t56...not as stock
1971 Chevelle ls6 cammed 5.3/700r4 turbo build.
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
