ramman: As we won't get into posting prices of equipment sold by suppliers, I'll suggest clicking over to the TDR Links. Under "exhaust", there is about eleven suppliers of systems. A call will give you an accurate price, and an oppurtunity to list and compare the systems, and to talk to a real person.
I've purchased the Banks stinger years ago for my '92, and last year Ted Jannetty improved the system from it's (Banks) original configuration. The Banks was much less restrictive than the stock, and the TJ mods. optimized the 1st gen system even further. I've since installed a Ted Jannetty 4" total system on my '98, and this system cannot be beat.
