Re: Exhaust upgrade question
Mine was 2.25(muffler size) in and out. The 5.7 is 2 in, 2 out but maybe you could convert to 2/2or get a 1 in, 2 out muffler. You could try running straight pipes in leu of the suitcase muffler with an X or H pipe. I remember someone posting that they did just that and liked it. When I tried it without an X pipe, it sounded terrible because(i think) the exhaust pulses overloaded the resonators. A single aftermarket muffler may hang down too far. I have the flowmaster DBXs. They fit around the driveshaft tunnel but if I had to do it over again, I would try the straight pipes with X or H pipe. H pipe would fit better in the tunnel leading to the rear of the vehicle. Search for a local shop that does custom exhaust work.
