I'm thinking about buying the Stage 3 Roush body kit from mrbodykit.com and if I get it I'm gonna need to get side-exit exhaust as well. I know they make side-exit catbacks, but is there any other way I can transform my exhaust to side-exit? What will I need? I currently have dynomax ultraflo mufflers on my 2000 gt. One more question, I have a chance to get some 4:10 gears for pretty cheap, is the rear end on my 2000gt 8:8?
