I’m 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 GM’s with the 5’6” bed. I have heard general concerns with any dual outlet system on modern trucks. Something with lack of clearance with spare tire, etc.

 

Well is it 4wd and what engine size is it. and is it automatic

 

dont want to hi-jack but
I have a 2007 new body style Silverado
1500 4x4 Crew cab 6.0 liter
also looking to maybe do true duals after cats
I have a dual in dual out muffler & excess to a pipe bender

 

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.
