My old bike had a 93 db sticker on it. The first thing I did was put an aftermarket exhaust on. Improved power heaps, but yes, bloody loud.
Falcon is pretty loud though, with headers, no cats, and a 2.5 inch exhaust, (only 1 muffler).
Manual EB V8 Fairmont Ghia
Headers, 2.5 inch exhaust, filter, lowered, 17 inch wheels, blah, blah
Hack = BMW m325i (Manual of course)
(OK, it's a 1987 model)
