To any of the other lads that were interested in this box its back up for sale as it would not connect to my 3 inch after market pipe this exhaust really is in great nick and i checked it out and these go for 200 sterling new on the web so at 60 it really is a bargain so ill offer it to the lads that replied here first before starting a new thread its 2.5 inch and will fit any turbo classic with a standard exhaust
