~TSP True Duals ?~
The Best V8 Stories One Small Block at Time
I've built over 400 TD systems in the last 5 years using Flo-Pro Twisters 75% of the time. Seen dyno sheets and time slips with just about every muffler option out there - including Magnaflow, Dynomax, and Flo-Pro on my own car. All made about the same amount of power - exactly the same on my car - and ran great at the track.
The only muffler I would be concerned about would be the Sweet Thunders. I don't believe they have a true 3" yet, so you're limited there, plus the 'chamber' style cuts on the insides just look restrictive to me. If someone has tested them head to head with a 'straight through' design and had good results - great. They do sound good - pretty much exactly like Twisters IMO...

For sound and drone, etc.. - just do a search. There's bound to be 100,000 threads on duals and mufflers for them...
