Are the exhaust test pipes/secondary cat deletes in the same location and fit for a 2013 r spec 5.0 the same as for the 3.8?
Roc did you order test pipes or took them off and had pipe welded in?Yep. Nice sound from engine, little added noise out at the rear. Passed emissions without a problem. When you see these cats you see the amount of inside restriction with the fine wires. Seems slightly more responsive particularly at high rpm( over 4000 to 6500). Engine definitely loves them off.
