It will bolt up fine. I HIGHLY recommend cats with LTs and a GMMG. While I've only heard the ORY clips on the internet, with cats there is ZERO rasp. I have some clips in my sig of both stock manifolds and Longtubes/Catted Y with a GMMG.

I don't mean to argue either but my car felt seat of the pants slower with the GMMG as well (after i took the magnaflow off). It wasn't just at low rpms. Throughout the powerband it felt slower. I definatly like the sound of the gmmg better though. It has a 3 inch pipe underneath but once you get to the chambers it is quite a bit smaller from there on out. I am thinking it is 2.25 or 2.5, I don't remember off the top of my head but I could go measure it if need be.

I have clips of my lt's, catted y, and magnaflow.

I think you'll be happier and save some money just by adding cats to your existing setup.

GMMG is way overhyped.

Wow! First time I've seen their Dual Dual setup. I bought mine a long time ago with the ugly 3.5 inch tips, had to put my own tips on it.

That is an awesome looking setup!

Great set up & it makes good power , just remove the cats if you want to hear it with stock manifolds though.

Well yeah, no cats make you raspy sounding.

Are those the clamps that came with the Magnaflow?

Sure looks they improved them on the newer kit as well, the ones that came with mine were half assed U clamps, those look nice!

Here's the Magnaflow with cats and LT's....in a tunnel
