I'm about to install the new exhuast soon and am going to sell the RB one. I was going to give first crack at it here if any one wants it but as soon as I get my new one on and this off It will be listed on Rx7club.com . I'm open to offers at this point, but please no low balling. The exhuast is in awsome shape but does have a small dent on the passenger tip and under the muffler. Its only superficial and did not crush any pipinng internally, so i does not effect performance. Also if you have an S5 rear bumper you can't notice the dented tip really, it was dented when I bought it by an s4 bumper which doesn't sit the same over the exhaust . I rescently had the exhaust off while installing the newer stock turbo and painted all the peices with gunmetal high temp paint. I've got a few pics and will take more when the exhaust comes off. This was the generation just before the all polished stainless one, it was all black with chrome tips.
You will need a fuel cut defender when installing this exhaust b/c you will exceed the 8psi boost fuel cut limit set by the factory ECU. This exhaust has been ran for over 2 years with a streetported 13bt without fuel adjustment so it shouldn't exceed the fuel limitations on a stock TII. I dyno'd once but had a vac leak and still produced ~200rwhp @ 5psi, a stock S4 TII is rated for 180hp at the flywheel. But generally boost is 10psi with out the leak.

1987-91 TURBO II Complete High Performance Exhaust System*
This is the ultimate exhaust for any Turbo II RX-7! Let your turbo breathe to it’s full potential with our “turbo-back” complete exhaust system.
The Turbo II High Performance Exhaust system incorporates a 3.15-inch (80mm) down pipe from the turbo outlet that mates to a presilencer section. From the head of the Y-pipe two 2.375-inch (60mm) pipes extend to the ceramic wool-packed 304-stainless steel rear main mufflers. The bolt-on exhaust system increases horsepower approximately 32% - a 59 HP increase on a 1987 Turbo II RX-7!
The Turbo II High Performance Exhaust system reduces exhaust gas back-pressure significantly, thereby allowing the un-assisted turbo boost pressure to increase to 10-11 psi. Our Fuel Cut Controller (part No. 11570 or 11571) is required to prevent fuel cutoff to the rear rotor above the factory pre-set limit.
This bolt-on system uses the stock mounting points for ease of installation. Each system is supplied with all necessary mounting hardware and gaskets (does not include turbo outlet gasket). The down pipe section is provided with a position for the oxygen sensor.
