On Friday night I installed the IPD Sport Exhaust kit on my 1992 245. I was surprised that the job went as well as it did. I went very slow and it took me about 3 hours from start to finish. The kit came with very good instructions and all of the parts went together well. I only had a little difficulty getting the old system off after the cat. I do not notice any improvement in horsepower, but the exhaust is a little louder (especially on start-up). I'll have to see how loud it is at highway speeds.
