I can get a local shop to make a custom exhaust for my Blazer that will fit exactly the way I want it to. The only thing is that it won't be mandrel bent. Does mandrel bending really make that much difference to rear wheel HP & torque in a cat-back exhaust and could I just go up a 1/4"-1/2" in diameter size of pipe to accomodate the bends? I figure it will be alot cheaper to get a local exhaust with a good muffler (like Flowmaster) rather than pay hundreds of dollars for mandrel bent pipes that will rust just as fast! Thanks Brian Still in search of the TBI KING!!
