I must say, I did enjoy the connection wars between SS and CheezIt.
So, here's my view of racing exhausts. Some are OK, but most sound horrible - for example, a 458 Italia with racing exhaust, or any V8 for that matter.
When I'm cruising along on the highway, I don't want to hear someone 7 cars back with a straight piped lawn mower cruising at 10k RPMs, engine screaming. Racing exhausts are for the track. They're like racing tires for the engine. They aren't necessary at all for the streets.
To whom it may concern: Please, please do us all a favor and don't use racing exhausts. We don't want to hear your twin turbo lawn mower Ferrari screaming like a cat being strangled.
