Full 3" American Thunder dual outlet system for LS1 cars. It will fit onto your 96,97 dual cat LT1 casr. I've had it on my car, the only difference is the driver side hanger is lower on LS1 cars so I used a clothes hanger and made up the 3" difference. Worked fine. The tips are the 3" slash cut cannons. It's pretty loud and I still have dual cats and have heard 80's and this is louder, so maybe it's a 40 series. I don't know.

The only thing wrong with the setup is the previous owner cut part of the hump-pipe to get it off or on his Camaro SS. I don't know why the idiot did it, BUT the pipe seals fine. There is still about an inch of actual length after the cut. I can get pics on request.

Price is firm. $300 + shipping.
