Flowmaster 40 series for side exit exhaust

Not familiar with the Spintech set up, although they look nice. My SVO side exhaust came with Borla mufflers. I would think they would be available directly from Borla, and you couldn't do any better on quality.
 
Thanks for the replies. I already have the side exit exhaust installed.. but the borla mufflers are way to quiet.

It sounds more european than american.

I just wanted to know if I could get some flows with the inlet/outlet on the same side so it would just be a swap.
