| Assuming you have 2-1-2 system 60mm will be a very very tight fit with a standard swing arm.
To exploit the full potential of the bigger pipes you would need to port the heads - not a requirement - but if your not going to do it theres no real need to buy the bigger diameter pipes other than pose value - think of it in terms of overall engine development rather than big pipes therefore big power, big pipes will accomodate more engine development than small pipes and therefore allow ultimately more power.
My S has 57's fitted and the heads ported and goes like stink with a PC3 and a custom map.
I could not say if the end box was the same or not, mines titanium tho' - bling! |
