Posted 28/02/07 12:00 PM Share Posted 28/02/07 12:00 PM (edited) I have an early BA MK1 XR6T, I have changed out the cat for a larger one, and my car has been tuned as high as mid 320's at the wheels... though with all the factory plumbing and the XR6T intercooler at time it was a fairly 'hard' tune... add the bigger intercooler and it's a pretty good piece of kit right from the factory.I've seen a couple of F6's tuned with Nizpro Stage 2 kits, with just dump and cat changes to around 360rwkw to 370rwkw...Jack Edited 28/02/07 12:02 PM by XR6T8_U Link to comment Share on other sites More sharing options...

A bigger dump pipe along with a larger cat will do very well... but as Paul said, injectors and stuff should always be done first, as these are the first thing to let the whole shebang down, it's not the exhaust.Jack Link to comment Share on other sites More sharing options...

I thought that the valve springs are upgraded over the xr6 turbo ones. Link to comment Share on other sites More sharing options...

What power figures are we talking about here? 350rwkw before exhaust needs to be done? Link to comment Share on other sites More sharing options...
