StEvO · Oct 13, 2007

so doing a lil comparison between the two today

~ Pm stub

size of stub entrance
~ height - 2.65cm
~ width - 2.7cm

~Sip downpipe

size of pipe entrance
~ height - 3.4cm
~ width - 3.3cm

~ malossi standard cylinder

size of exit
~ height - 2.6cm
~ width - 2.7cm

comparison picture of the two

so PM have designed there stub based on a standard 172 as it is nearly an exact match.

now sip have the right idea for the stock pipe, making the most of whats avaliable for easy power.

going to have a nice long convo with graham about producing a SS stub,
based on a larger exit people can match easily as i no afew mates who weld.
