IMO, the longtubes will have a more mellow sound than what you have now.
Stock manifolds, off-road mid and SLPs have got to be the LOUDEST set-up with these mod motors.
I got BBk longtubes, o/r x-pipe and magnaflow magnapacks (which aren't much diff than the LM1s) and I think it sounds great. There is no popping or crackling whatsoever. I was a little worried it would be loud as hell, but it seems like the LTs mellow, smooth out the noise some???
I can't really explain it. Here's a short vid of this set-up: [ame="http://www.youtube.com/watch?v=BUEONPApYdo&feature=channel_page"]YouTube- 01 Mustang GT / short exhaust rev[/ame]
edit: ARE they worth it? If you pay $600 for decent LTs for the noise factor, I would say NO that's not worth it. I would do cams at the same time. My car picked up about 40hp from cams and longtubes. I don't know how much the cams and/or lontubes would have been worth alone, but after doing some research, they obviously help each other make more total power. With your PI-swapped '97 block motor, you still should be able to run anybody's Stage 1 with no piston-to-valve problems, but you should do a lot of research on it.
