I just grabbed a brand new Raptor exhaust system from the Cat to the dual outs and thought it would help the performance on my 010 5.4, I have a K&N fresh air box installed already,Im asking for opinions on this chioce, will it help or hurt. Thanks Scudapie

Will give it a little better sound but its not going to do anything for performance.

I have it on mine and like it. Nothing for performance. Just a little rumble and no drone with a 24' camper.

I have the raptor exhaust on my 2010 lariat, it has a great low rumble and full throttle sound, not much louder than stock but noticeable. I'll try to post up a video sometime soon.

Thanks Dudes, Any thoughts on weather or not I should use the resonator.It was suggested to me that I should just leave it out of the system.

Not sure about the resonator, I have the 40 series Flowmaster split into duals and an S&B CAI and it sounds a lot better...not too loud or "droney", but the big difference as mentioned above was adding the 5* tuning. That made the old 5.4 a lot more perky.

safe money all together and remove the muffler and and keep the resonator here's my 6.2 with no muffler and resonator I have the tip side exit before the tire https://youtu.be/AId-RvZ9pPM
