Well since i switched from the turbo plan to the S/C i decided to do a custom exhaust on my Axiom. I started with one of my Morgan-tec stainless mufflers, single in dual out. Then i bent up a custom set of 2.25" aluminumized pipes. All of this ends in a set of 4" oval stainless tips that i cut receses in the bumper cover for. I am very pleased with the outcome, deep idle and awsome sound. It really picked up the throttle responce and seems to have helped the top end some as well. It was a little tight on the drivers side crosover pipe but it can be done with a little skill, i actually could have fit 2.5" if i would have tried. No dyno #s yet but that will come very soon. Here are some pics and i will try to get a sound clip soon. Let me know what you think.
Thanks for any feedback.
