Has anyone replaced their cat converter?
Just curious if anyone found a replacement that yeilded better mpg and performance. I ask because I think mine is rattling and may be going bad.
'06 silver 4.7 4x4, 2" Rough Country lift, 265/70/17 Goodyear Wrangler Duratracs, 17 x 8.5 MB V-Drive wheels, AEM Brute Force CAI, Optima Red Top, Bilstein HD struts up front, and a couple really cool stickers that add somewhere between 10-13 HP
