I'm looking to install a pair of the new 450's, but am hesitant because I have stretched/extended bags. Would hate to purchase and then find out the pipes touch the inner side of my bags. Any input from someone who has experienced this?

 

No experience with 450s, but I had 5" stretched bags on a Limited Ultra with V&H High Output slip ons, and I would've had plenty of room for the 450s.
