Fairly new, ceramic coated with Y pipe. Fits single 3" cat TPI cars. New they are in the $600 range...I will take $300 plus shipping costs.

Bought them for my new motor, but they would not flow well enough for my motor to make peak power. They would work very well on a stock 305 all the way to a mild 350 though. I only have about 1000 miles on them (plus some dyno time), and they are in good shape.

I am not on here frequently....do not reply to this thread if you want a quick answer. Send a PM or better yet, an email to me at jmeinerz at gmail dot com.
