I want to sell an SLP Stainless Steel Power-Flo Axle-Back Exhaust 2005+ Mustang GT w/ 4 inch Tips, pt # SLP M31012. Most of you already know they produce a nice mellow sound but they are not loud enough for me. The loudmouths’ I have on the Bullitt now are loud enough but the Factory H-pipe has an orifice plate in it with a 5/8" hole. I'm still not quite pleased with the sound and would like to have an H-pipe w/o the orifice. With that said I am willing to partial trade a Factory GT H-pipe (prefer 2008-2009) for this axle back. Retail is $499.95 and a certain popular panhandle mail-order parts house is selling them new @ $449.96. They only have 100 miles on them at the most. As mentioned I will partial trade for a GT H-pipe, or sell outright for $275.00.
