The Supreme SP for ’09-’14 Acura TSX offers a refine exhaust note with elegant styling to match. The classic dual oval muffler system with large free flowing 63.5mm (2.5”) piping produces no exhaust drone. Thanks to the two large SP mufflers, it has excellent sound suppression at idle and cruising. In spirited acceleration, the exhaust note comes to life with a deep rich GReddy sound. The muffler and tip best match the TSX’s aero styling.
