Horrible drone in the low rpms. New clamps, no leaks. I installed 2" motorcycle cheapo baffles to test the sound. Works amazingly. NO drone. Quiet in the cab top up, or top down. Still a nice and raspy sound out side and behind the car. I ordered a set of 2" car chemistry baffles. $100 for two. I think they will bring back some low tones and flow better. Will update with pics when they arrive. __________________ _________________ 1999 BOXSTER
