If your running true duals on a LO3, (modified, but its not huge), if I use 2.5" bends that are crimped, it shouldnt be an issue because the dual exhaust will support huge horsepower anyway, right?

I'm hoping for 300 flywheel HP from it, think that will be supportable?

 

Depends on how small the crimps make it, but with true duals you'll be fine.
