when looking over the mandrel bend exhaust systems for sale, the price is plenty. and since i have the bend-pak pipe bender in my shop, how much restriction (from non-mandrel bends) would one get from a 2.75 system? the three inch is a very tight fit. in a 2.75 pipe my bends would be reduced to 2.5 im not building a drag car, but it seems we like these cars to go. and a good flowing exhaust, is just part of the puzzle :six:
