    switching exhaust

    I put pacesetter lt's with a catless y pipe on in the fall and i love the way it sounds at higher rpms with my Lm. The problem is I think it sounds like shit when i am going through the gears around town normally. (3500rpms and under) What could i do to make it sound a little cleaner down low while staying real LOUD. I heard great things about the tsp true duals but never heard it in person. If you guys have any advice i would appreciate it.

    Get a new cat back or put a larger case muffler on.

    i would have a magnaflow welded in place of the lm and at the same time have a cutout installed before the magnaflow so you could have it loud when you want and a lot quieter when you wanted that.
