The exhaust sounds exactly the same as the R33 as they are made to the same spec. The exhaust will fit the 4 door model BUT the 4 door shells are 40mm longer than the 2 door shells so the tailpipe will sit slightly further into the bumper, i dont think this will be a problem unless you had an aftermarket bumper fitted.late reply but how much are they and i hope they sound the same to the R33 one's
and will i need to extend the piping or can you do that?
Wont work im afraid as to add 40mm into the system at the cat/decat end puts all the bends in the wrong place, and the hangers at the end wont line up properly.Just make or let sommeone make a flange [think thats the word for it] doesnt have to be verry thick so shouldnt be much of a problem.
you can make one just like where the exhaust starts and bolds on, same size and fit it between the cat or decat and catback exhaust.
