2015 suburban headers and exhaust.
I'm wanting to put a complete exhaust system on my 2015 5.3L suburban I'm looking to do the headers first and finish the rest off sometime in the future. Just wondering if anyone else has done it and can suggest headers and exhaust that will fit.

Welcome to the forum.
Always wondered what happens to the PUP CATs (they're the ones close to the heads) when using headers. Without changes to intake and heads, not much in the way of gains will be achieved. Check w/ most of the major exhaust mfgs to see what's available.
