I am wanting to clamp up the the pacesetter longtubes to a 3 inch summit x-pipe and wasn't sure if the longtubes had a 3 inch outside diameter collector. I know the longtubes are slip fit for their y-pipe so I don't know if the longtube collectors are just under a 3 inch outside diameter to get the y-pipe to work. Thanks for any help.

 

Pacesetters are 3 in outside diameter, i just measured mine to get band clamps ordered. The pacesetter Y is 3in inside diameter.
