Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Can't help with a SpeedArt for a 997, but FWIW, I've had a SpeedArt Sport exhaust for several years on my Cayman S and it brings a smile to my face every time I drive the car. It's gotten more mellow, richer and deeper over the years. Doesn't intrude on conversations or audio books when cruising, but you definitely hear me coming at WOT. I love its sound during throttle blips when heel and toe downshifting. Nice throaty idle. Well made. Nice diameter, internally perforated tips. I don't believe SpeedArt's claimed power gains based on my comparative track experience, but I haven't dyno'd it and bought it just for the sound. Highly recommended. http://www.planet-9.com/cayman-boxs...ayman-boxster-modifications/16122-after-market-exhaust-overload.html#post191758
