Got the Magnaflow muffler today and did the stock air box mod....Used a sheetrock knife(razor blade knife) cut perfectly....Anyway I have read the ECU will make some adjustments....How long will it take???
What year is your truck? I just got a 2008 and the exhaust is differnt then the 06 that I had. I still have my magnaflow for the 06 and I was hoping to install it on the 08.
Welcome to both of you if I haven't already. To answer your question, the exhaust did change. It went from a y-pipe single in single out to a no y-pipe double in single out in 08.
