I have just purchase a set of 50mm Termignoni pipes for my 916. The pipes came off a 996 and come complete with size convertor pipe, straps, springs and the E-prom. What do I need to do to put these on my 916 and what difference can I expect.
You'll need some spanners and allen keys and a chip puller & a little bit of time to line them up straight. I would recommend making sure you have the right chip for 916 with 50mm cans.
Power gain - absolutely nothing in my experience. Sound and look good though.
