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.
