dynomax super turbos

The 2 1/2" super turbos are 2 1/4" internally. And the offset in center out design flows like crap due to the center pipe right in the way when the exhaust tries to make the 180 degree turn. And after that 180 degree turn the 2 1/4" pipe is just cut straight not tapered out to facilitate flow. When I took them off my car and swapped on some Ultra Flo's it was like a cork was taken out of the exhaust. The offset in offset out super turbos are a much better design because the exhaust does not have to squeeze around that middle outlet pipe.

I had a early generation of Accurate mufflers on my GTS along with the Accurate 2 1/4" compression bent system. Could never figure out why the car didn't perform the way it should have. I cut these off:

and replaced them with a pair of Dyno Max Super Turbos. With no other changes, the GTS went almost a FULL SECOND faster and it picked up 4MPH! Not bad for $84!! Since then I have replaced that system with a TTi X-pipe 2 1/2" mandrell bent with Dyno Max Ultra Flo mufflers. That was worth another 2 tenths faster in ET and another 1 1/2 mph as well.
