I've just had my downpipe replaced with some difficulty with the BBP downpipe purchased from Ebay for $192.95, was $500 with a hi-flow cat. for installation. Needed an O2 sensor installed aswell as the pyrometer along with some adjustments to the dimensions of the pipe itself. It was also too long even for a cat eliminator to be fitted to my existing exhaust so it had to be cut up. All in all, it came up pretty well and my existing power output before fitment was 171.4kw at the wheels @ 13PSI with a boost leak. Leak has been fixed and the Final dyno tune will be done on Monday and will update as soon as I get the car home.
