Supersprint do one, available in the uk from eurostyling, stockists are places like ripspeed, demon geeks, TSR performance (highly recommended) Wouldn't recommend Powerflow, they're not full on stainless steel and have a tendancy to rot and fall apart (lifetime warranty though, so at least they'll replace it!), dunno where you are, but there is a place in SOuthampton called Stealth systems, they'll make you a top quality ss exhaust, i have a few mates who have them and you won't find better, gonna go down they're myself when i've got some money and see what they'll do for me. They also do supercharger conversions aswell, they're currently working on a celica `t-sport` with 250bhp plus.
