I've been looking and doing a little research for brand and options for some time now... Settled on Magnaflow as I've read FM has more restricted air flow. Now I need to decide whether to do a muffler swap or a full cat-back system. Pros & Cons for each on performance?
If you want to get a cat-back to make your truck dual it wont work... you wont have the factory hangers to attach it to. My recommendation is get the muffler that comes in the kit PN#12588 and have a shop make you a custom cat-back since they can fab the hangers for you.
