Will this system work with the Roush Axle Back system that comes with the Roush Level 2 Power Pack for my 2015 GT?
I have the mbrp street cat back exhaust, will these link up correctly?
I am trying to decide between the catted and non catted version of these headers. Any performance or sound difference?
Will the lund tune be count as a custom tune, after writing this part in the description when purchasing the lund tune??
Where do you get the required tune from
I have a supercharged 2015 5.0 I have a catted x pipe along with magnaflow magnapacks..the exhaust note is very aggressive but the tone is to raspy and high pitched sound. Will getting these headers and a o/r hpipe give me the low rumble i am looking for?
Will these headers work along with magna flow competition cat back exhaust and its included X pipe?
Will these headers throw a CEL (check engine light) ?
