Selling my S.U. Test pipe woth mounting bolts. Direct bolt on replacement for any MazdaSpeed6 2nd cat. Will NOT trigger a check engine light. Good for those looking for subtle difference in exhaust note coupled with a increase in HP... $90 shipped in the conti-U.S.
here is the info from the mfg site...
"The S.U. Catless Test Pipe replaces the second catalytic converter on your MAZDASPEED 6. It is constructed using 2.5" SUS 304 Stainless Steel Tubing and CNC machined flanges. The S.U. Test Pipe is designed to be a straight tube without any bends allowing for the straightest exhaust flow. The S.U. Test Pipe removes the severe air flow restriction that the stock cat inhibits onto the MS6 exhaust system. Removing this restriction will greatly improve the performance and power for your MS6.
The S.U. Test Pipe is a direct bolt on replacement for the second catalytic converter. For flexibility, it reuses the stock donut flange system to allow for necessary movement. The removal of the 2nd cat will NOT trigger any check engine lights. The test pipe will bolt right up to both the stock and aftermarket catback exhaust systems."
