sorry to hear about your problem, I dont know what to suggest about the sound problem other than the backwards muffler comment that was already mentioned. The power problem may be your computer. When I installed my LT's, it felt slow, but after about a week, I noticed the "lag" was gone and it seemed to pick up power across the whole rpm range. The computer just had to relearn itself. In your case, maybe driving around open headers freaked out your computer?? Just my $.02

Mine is in the I pipe. THere is a little area that is perfect for it and you won't lose any ground clearance
you said you used cats when you had the shorties on, are you using the same ones? could they be getting clogged? why dont you just grab a backpressure tester that will tell you if you actually have a problem or not.

You know how loud stangs are with off road h pipes and flows. Well those cars are running the shorties most of the time. We put some longtubes on a GT and it got way quieter.
Since when do long tubes quiet down an exhaust compared to stock manifolds.
My exhaust is definitely louder than before the long tubes. And I still have cats. (heads/cam are almost installed, should be done by noon tomorrow, so that isn't a factor..... yet).

About raspy: Open headers wasn't rasp, that was just plain noise. If that's rasp then hell, i love rasp.
