My 1996 STS. Testing video and having fun with it. Closed course. No red-lining is involved in this video. The STS is equipped with a train horn and Flowmaster mufflers. Other than that, it's bone stock.
Before and after video of 1996 Cadillac Seville STS. First part = OEM mufflers, second part = Flowmaster 40 series.MUCH quieter on the inside, MUCH! No annoying back noise. Sounds sweet on the outside!
My 2000 Cadillac STS-i replica. cold air intake, cat removed, and Magna Flow Mufflers. Just a couple quick runs down the street. If you guy's like it I will make more. Thanks for watching.
