997 S Quarter Mile Times

[JMA -997]

Just curious.... What sort of quarter mile times can a 3.8 997S with 200 cel cats and a high flow exhaust expect to make??? :rolleyes:

I don't think there's any independent evidence to rely on, you might ask the manufacturer of the exhaust and cats. Since their numbers have been shown to be optimistic and based on limited testing, I'm not sure that will do much for you. Unless you want to be out-of-pocket for extensive and expensive testing I'd just rely on what most people do to gauge the effectiveness of these mods--the butt dyno or lap time.

While the high-flow cats might make a difference in power, they may not pass a visual or smog inspection depending on your state. They could also interfere with the engine management, which isn't designed to accommodate them. As for the performance exhausts, it's worth noting that Porsche's "sport" exhaust option is just a "loud valve" with no performance effect; I take that as a sign that the stock exhaust is designed for maximum efficiency and power delivery within regulatory, noise and packaging constraints.

If you find some numbers please post them, I'm curious too.

I did a 0 to 60 mph in 4.8 seconds. Looking at the

graph, i think this would work to a 14.4 in the quarter mile.
