ASM.... you probably got that 'tinny' term from my description of Gardner's exhaust, but I wasn't referring to the 'chambered sound' (I love the factory chambered sound even though it's a horsepower robber). I was referring to ANY Stainless Steel exhaust as sounding 'tinny'. that is due to the fact that the metal used in stainless steel exhausts are thinner, less mass, and vibrate/resonate at higher frequencies than does heavier gauge steel (such as is used in aluminized exhaust components). If you feel the need to install chambered (because your car came that way, or if you just 'love the sound'), there are chambered system manufacturers that make their parts using heavier gauge metal (ie. Allen's Exhaust and others)...
