gladly, my trk is catless however (was when i bought it and i noticed some blue smoke no sense in installing one and stopping it up in a few months) and i will have some in cab resonation, but being that mine is an extended cab i have more than 40 inches of room to put it b4 the axle. if your really worried about resonation i suggest a shorter muffler thats quiet as close to the axle as possible and goes over the axle, this is experience talking. im going w/ the longer 40" vette pipe (since its only 135 bux and really long so it should have wonderful sound deadening properties) and mounting it close to the dump over. i can almost tell you i will have resonation since i dont have a cat, but its better than the current exhaust leak that i hear thru my floorboard thats driving me nutz. i dont really like popping in the floorboard area when i downshift to slow down, my valves must be loving it.
