I don't know about you guys but I whacked on an ebay rear silencer, some of the ebay headers and did before and after dyno runs at the same place and showed real improvements from 3-3.5k rpm. I did the same with the 996 throttle body and with a subsequent remap. Granted this is all on a 3.2 rather than 2.5 but the basic principles are the same. Those exhaust parts were so cheap is was rude not to have a go, like £130 and £110. Of course in the UK there is only one set of cats to worry about too.
