No rattles anywhere in the exhaust system. I've used chassis ears to listen directly to the muffler and all exhaust components while it's making the sound. Not a single noise from the pipes, manifolds or muffler. The sound comes out of the exhaust pipes. It sounds like air from an air pump, like an air compressor without the loud motor. Could this have something to do with the secondary air pumpby snelso15 - Main Forum
2001 Porsche Boxster S, manual 6 speed. 45k miles. Only modification is the following exhaust. I recently completed some exhaust work. Removed the secondary Cats and replaced the muffler with a Circuit Works V2. Right after this modification I have very noticeable noise in the exhaust while decelerating. I notice it from 3500 RPM's down to 1400 RPM's. It may be doing this above 3500 but too manyby snelso15 - Main Forum
