Ya, I have I put them on my 99 frc, and they fit very well, and have improved the sound and performance of the exhaust. I would only do one thing different I would get them coated prior to install as this would help with the underhood heat. Did it on my lift in my garage and it took me longer to get the stock exhaust off then to install the dynomaxx. It just barely passed the im240 emissions test here in Denver. Again the coating would help to keep the cats hotter and burn cleaner. I got them for a fair price as a local shop was trying to become a retailer and sold them to me for about 1200 bones. That was my major driving factor. If you do the install of any long tube headers and have a stock clutch do the clutch at the same time. As it is about 30% of the work needed to install the clutch. It is a real pain i.e. remove headers etc. after you just put them in!!! Headers finished off my stock clutch. I have had to rmv the headers and drop the diff/trans etc. and I ended up doing header install twice.

They are supposed to be great.

Ya, they are louder but it is not over the top. If I had to guess I would say about 10-15% louder outside, and 5-10% louder inside. There is a horsepower increase. I would say around 20-25 hp at crank just a guess, I have not been to a dyno, but it helped me eat my clutch.
