Hey guys, my uncle has an 08 F-150 with a 5.4. He is looking for more power, for towing purposes. We were thinking a tuner and cat back exhaust. What tuner and exhaust would you recommend? Also anything else that that would really improve towing power?

Thanks!

 

You're on the right track. Cat-back or true dual exhaust, tuner & GOTTS mod. Headers and taller gears are another option. 3:73 or 4:10
For towing, I think a single 3" catback would be better if you go that route. For true duals, 2 1/4 or 2 1/2 is good. The SCT tuner is very popular here.
