You guys think i would see any real world track or dyno gains by switching from my TSP catted Y/dynomouth to a Sweet Thunder Tru-Dual setup Alot of local guys running ORY's seem to be quicker than me with really similar setups

 

With that kind of nitrous setup I think the true duals will show a noticeable gain. If you are heavy into drag racing a 4.10 gear may help compensate for the lack of backpressure, but try it out first with your 3.73s and see. You'll definately have a lot louder exhaust at least!

 

I think you'd be more than pleased with the ST duals setup no matter if you picked up power or not. My guess is that yes you would see about 10-15rwhp n/a from swapping to the duals.

I would NOT advise putting 4.10's in an automatic though. Back pressure isn't going to be an issue with a 3600 stall.

 

If it weren't for the no-cats smell, I'd go duals definately. My TSP Catted-Y I put on after my ORY (emissions, I couldn't deal w/ the smell either) I felt a 'pants-in-seat' difference in power, definately lost some ponies. I'm sure w/ duals you'd pick up a ton
