Taking them to a muffler shop Monday to see what he can come up with. The quality of these headers are great and the fitment is excellent. I went from the bottom to install both. Ditched the factory bolts for the black ARP header bolts. Fired it up for the first time which was straight open headers and Wow these sound crazy mean. Can't wait to get the cats on and everything buttoned up to do some driving and open her up.

Hey so I was wondering what changes to the cats did the exhaust shop do so they can fit the mbrp exhaust? Also how exactly do the cats not fit?
