Size of 05-06 stock muffler inlet (pipe size)?
Is it 1.75 or 2.25 or 2.5? I couldn't find this information in the forum
And do any1 know if aftermarket mufflers have improvement over stock ones mid low range? I heard people saying the 02-04 Base ones are very restrictive.. does it mean 05-06 mufflers are less restrictive?? yea.. at high rpm stock ones are always more restricting, but i was wondering for low and mid range gains it is worth replacing the stock axleback? 2% gain for me is a pass`~~~ (oh, the context is that i am modding intake, manifold gasket, header and axleback and ecu tuning)
thanks in advance tho
