RE: collari 32 vs sure fire 32?
one thing about tuned pipes is the fact that there is no one general good pipe...what works like a charm on one motor will not work the same on another...so that pipe may suit the Nova very well but actualy hinder the STS 28.......I know my 24/7 pro was a dog with the ribbed and a monster with the GH single......there was a huge difference in power..yet the ribbed works very well with alot of other engines..........
there are guys who have both the OS 30 and the LRP Spec 2 and they say the Spec 2 is a fair bit more powerful.......so I would predict the Spec 2 is likely very close to the Nova...........the New SH 28 Pro is the same as the Spec 2.......
