What kind of cats are they using?
I have QTP badged headers and the aluminum Y pipe is / looks like a pile of crap. I'm likely having Mufflex make me a SS Y and I might as well swap out the Catco cats I'm currently using.

i can take a sound clip once mine is on with the new merge, (hopefully by the end of this week or mid next week). It will be Kooks 1 3/4 LT's and the offroad Y going into a slp LM2....i may know someone running the old version with a gmmg if youre interested

Does anyone know the diameter of the kooks cat?
I like the Magnaflow Universal 99659HM, but I'm afraid the 5" diameter is too wide to fit just off the headers
There is also the 59959 which is a 4" diameter
What is the difference between pre-OBD2 (59959) and OBD2 (99659)...does it matter for us?

Another clip for anyone interested. Huge fan of the new merge. Sounds fantastic with the Kooks 1 3/4 headers and Magnaflow catback. All of the jackhammer light acceleration noise from the previous "T" merge is gone and replaced with a clean burble. It's a little harsher than with a dual 3 inch to 4 inch Flowmaster merge I've also ran but this had much better fitment and I can use the Spohn straight crossmember and this exhaust with near factory-like ground clearance.
