I own 2 supras, the twin turbo and the older single turbo modle. They both perform like champs with straight through mufflers. YOu dont want any chambered exuast on your GT cruiser!
As fot teh SRT-4, we are putting down 215-230 to the wheels stock. OUr front mount is larger but I dont think that makes a big difference in dyno numbers. You need some strong front air running into the FMIC to make a difference. If you put a GT FMIC on the SRT, i dont think youwill see a difference in the dyno.
Now what makes a difference is the design of the intake manifold. The SRT manifod tappered down which gives you good velocity going into the head.
