Thanks for the feedback.
Stock tail pipes are 67mm, so not much of an increase. I am however a bit put off by the fact that it sounds like a PITA to fit to the down pipe. I dont really want to be getting the welder out to fit it.
How often do millteks come up second hand? I need to do somthing fairly soon (preferably before the run out to Le Mans in June) so my hand may be forced to go for the Jetex.
How much louder are we talking, I dont really want it much lounder than standard if possible.
Besides Jetex, Milltek and OEM/S4, there is really nothing else, the Neuspeed one is as expensive as a milltek, and the factors ones will undoubtly be a bad fit and approx £240 too, so may as well spend the extra and get the Jetex.
Not really sure what to do.
