Default Cat Back Exhaust for 2009 Chevy Crew Cab

Im shopping for a cat back exhaust system for my 09 Silverado 1500 crew cab. I like what I hear about Magnaflow but they only offer their systems with single passenger side exit or dual rear exit. I would prefer left and right side exit. This option is offered from FlowMaster, Borla, Gibson and MBRP.
Whose cat back systems have you worked with and what pros / cons have you encountered? Especially when working on GMs with the 56 bed. I have heard general concerns with any dual outlet system on modern trucks. Something with lack of clearance with spare tire, etc.

Manaflows are a great choice, but like most things in life, it is all a matter of opinion. Personally I like Magnaflows because they give the truck a deep rumble outside, but won't drive you crazy on the inside. Tip placement definitely plays a roll in that as well. If there isn't a kit that does what you like just take it to a muffler shop. They can bend up just about anything you want and normally (around here anyway) it comes out cheaper than buying a kit. I just did a magnaflow 2 into 1 with a single stainless tip in the factory location on my dually and it was $150. They had to replace the pipes from the muffler back too b/c the set-up that was on there wasn't in the best of shape.
