yeah i have pacesetter cerimic coating longtubes, the guy made it 2.5 all the way back .

as for the sound, the magnum motor just sounded totally diffrent, when they 1st started it up to take it out of the garage i was in aw because it was it sounded so good and its just loud (but thats because im running streight headers most of the time) def a mod to do power is diffrent also. check out my youtube for vids however sound dont do justice for how it sounds in person but you will get the point
