SMB FD RX-7 Dump pipe 3.5"

The geniune SMB dump pipe is best upgraded dump pipe for the FD RX-7, 100% Aussie made, tried and tested for many decades. This cobra head dump pipe suits the twin turbos and bolts directly onto our SP Mufflers mid-pipe and catback exhaust, completing a full 3.5" exhaust system. The rear turbo gasket AND studs should be replaced when changing the dump pipe to prevent leakage or broken studs. Please de-select gasket/stud kit from the drop down if you don't want these included. Due to the extreme heat produced by the 13b, genuine studs MUST be fitted to prevent serious failure. These are not your run of the mill studs, and are made from a special metal to withstand the extreme conditions.
