I was set to order another 4in. turbo back magnaflow just like I had on my 04 until I crawled under my new truck and realized there is a cat delete pipe installed :thumb:

With a moderate SCT tune from DJ can I really gain much going with an aftermarket exhaust above what my Catless system can achieve? I realize the sound is better with a magnaflow but I just hate to rip off a perfectly (like new) exhaust system......

is the stock muffler still there? If it is I'd say straight pipe it, or install a free flow design and leave it at that. As long as you have only "moderate" power goals I think you'll be fine.

Yep, muffler is still there. I'm gonna visit my local muffler shop and see if they can slip in a piece of SS pipe in its place.
