go out and listen to as many as possible. Porsche actually invested hundreds of hours and mucho $$$ into the OEM exhaust so think about that before you decide to swap out the old one. Porsche spends millions of dollars just on exhaust tuning each year so think about that before you buy. It's no wonder some aftermarket systems actually lost hp.....Porsche does it's homework and spends mucho $$ on this kinda stuff.
