Any bolt on aftermarket dual exhaust?

Just finished a 350 swap bolted the headers up and now I'm looking to do the exhaust. The car has most of the UMI catalog underneath including sub frame connectors so clearance is gonna be tough. My question is does anyone know of a true 2 1/2in dual system that I can bolt and weld right on or am I gonna have to get something custom made?
Thoughts? Experiences?

Thanks!

There is a dynomax kit that seems to have fitment issues. Also any fitment issues will be magnified by the subframe connectors. True dual is a PITA running 2.5 to a 3" collector then 3" all the way back should get you where you need to be.
