I would put the system on first and see what you think with the resonator inline before you cut it... I know alot of people put the glasspack in, but i didn't and I love the way mine sounds. It's loud in a good way!

 

Get a 25' glasspack when it comes down to it.

I have a 31' and I hate it, Graphites is smaller and is a lot cleaner...more rumbling. Not like a giant fart like mine

 

alright sounds good.. I actually went out and bought the glasspack that was 30.5" but just took it back today and exchanged it for a 23.5" glasspack.. hopefully it sounds good.. ill try and post up a video of it when its all done next tuesday!
