Title: Building an exhaust
Post by: Brett on July 21, 2005, 12:46:24 PM
Out of interest, when making an exhaust, do I need to give it any expansion chambers etc? Its going on a TII thats been \'breathed on\' slightly. ;)

Just make sure that the pipe is not going to restrict flow. Oh and some form of baffle(s) would be a good idea.

But what about when the plod pulls you over for being tooo making to much noise, or when you fail your MOT for being too loud.

I\'m planning on removeable baffles, quite softly softly catchy monkey for most of the time :)
