People make such mistakes for the sake of car looking "cool"! 4.4 exhaust thrust is not the same as 4.8 actually I would say if it was between 4.6 and 4.8 maybe better as the two differ by only 3 Horse Power. The exhaust gases/pressure is well calculated according to the engine size going 4.8 to 4.4 is really reducing the @ss of your car... do it and come tomorrow and tell us how constipated your car is!...
