I think that the performance advantage of an exhaust pipe comes not from back pressure, but from suction produced by the momentum of the exhaust gasses in a tuned pipe.
I am running 165/80/13's on my 1.3 auto lsi 4dt. getting 44. as i drive 50 miles to work one way, the cd matter more than weight. and weight is easier for me the fix than body style. (i dont do anything weight wise right now on my car). On the muffler thats why i think its best to run a pipe all the way back. You can then tune it by changing the size. But you dont need a muffler on these engines.
