Personally I would have thought this would increase performance as the miltek 2.5" does.... Is there such a thing as an exhaust thats too big???? is air freeflow too much a possibility???

cheers

not really on a turbo car. the quicker you get the gases out the quicker the turbo spools up. my magnex is only 2 1/4 and works up to 200hp with out any problem. the CAT on the other hand can cause restrictive back pressure if you tune the crap out of your car.
