Jessie, I installed the IPD sport exhaust on my '92 245. I had just put in the VX cam and timing gear when the exhaust system failed - so it was a matter of a sale prie and the opportunity. The IPD system is basically the Turbo exhaust system with a straight pipe in place of the front muffler; FCP Groton has a good price on the Turbo exhaust, but you'll have to make up your own adapter pipe, which should not be rocket science. The whole system is either 2-1/4 or 2-1/2 in diameter, larger than the non-turbo system. In my car the sound is quite nice, clearly throatier than stock and close to 'loud' from 2500-3000 rpm. I can't tell if there's any more kick becuse the cam is clearly the greter effect in my car, and I sincerely doubt any improvement in fuel mileage (I get 28 mpg in warm weather). However, the under-axle pipe clearance was a problem. I could get it to clear in the driveway, but once I drove around it would start banging again. I found some 1 x 3/8 steel stock at work and made an extension bracket for my exhaust hanger, which worked like a champ. I cut the stock about 2-1/2 inches long and drilled a hole in each end. I removed the stock hanger pin and found a matching metric bolt and nut at the hardware store. I bolted the old hanger to one end of the new bracket, using the new nut, then bolted the other end to the car using the new bolt (did the same on both sides of the car, of course). The new hanger-to-hanger dimension is reduced by two thicknesses of stock (about 3/4"), but this doesn't hurt a thing. The muffler now hangs about 1.5 inches lower and doesn't touch the axle at all.
