Spiral Flow REVIEW! Well, you never really hear to much about the Moroso Spiral Flows.
My exhuast experience -
Stock
Stock with cutout
TSP X pipe with Sweet Thunders
Custom (non crossover) True Duals with Sweet Thunders and Side exit.
TSP X Pipe with Moroso Spiral Flows
The Spiral Flows are the BEST sounding setup to date... with the cam I have they hit like a muffled 5.0 (the deep resonance sound) but aren't overly megaphone loud. The car has that LS1 sound but with the same feel as a dumped 5.0 with a cam.
I will say I have heard the Bullets and don't care for them at all. The sweet thunders were great but, like many people say, they have no TONE to them...Just sound, but no real tone.
If you like those 9 second, quite, small blocks at the track that really thump but don't megaphone there sound, the Spiral Flows are for you.
THANKS TSP! THANKS MOROSO!

i've had about 5 different y-back exhausts on my car in the past year. up untill 2 weeks ago was a MSv3 cam only LS1 & boltons.
factory SS chambered - decent idle, kinda raspy though
bullet on Y - race car idle, WAY TO LOUD and obnoxious, kinda raspy too
spiralflow on Y - very nice idle, just a little loud crusing (th350 and 3.73's.....)
TSP rumbler catback - nice idle, raspy as hell
TSP rumbler w/spiralflow in place of bullet, currently - great idle, nice tone at cruise (3k rpms), not TO loud at WOT, and NOT RASPY AT ALL!!!!!!!!!!!!
i can say with this muffler, its not raspy at all. first LS1 i've ever heard around here(MS) that wasn't raspy at all. some friends have even bought the spiralflow for their cars because of the way it sounds on mine.
now with the 370, heads, and bigger cam. the exhaust sounds even more awesome!!!

SlowScott- The Sweet Thunders are louder and more 'defined' then the Spiral Flows...they lack the resonance and bass that the SFs have...very 'raspy' as well.
As far as the Sound Clips go, you really won't be able to tell the difference on a computer speaker. The resonance and hum of the spiral flows would get lost.

i lost 4rwhp from going from dual 3" cutouts ...to 3" duals under the axle clear out the back. i had the mufflers directly behind my exhaust tips. there is a nice pocket for the mufflers to sit behind the tips.
