I have. Dead spot when I step on my throttle the truck hesitates then takes off any ideas on what it could be?

 

If it is not throwing a code do a tune up, and clean the MAF.

 

The check engine light went out so i don't know yet but it also has a skip and I still have to clean the hole throttle body and order my dual 3" exhaust.. Thanks for the info

 

Dual 3" is a little too big unless you're going force induction.

 

Nope but we have ran it before so we will see how it works outta be good sounding!! They have a vid on YouTube with a guy running a 4" off a 5.4 no different than my buddies running dual 3" then stepping it down to 2.5" n making it sound like pop corn in a tin can sounds like **** if u ask me I want thrifty raw horse power sound and for it to be able to breath when I have a good load on it and pulling a trailer

 

May sound decent but the powerband will be raised. Raw horsepower is best at 2.5" duals.

 

Yeah I'm not too worried it makes it dogish but gives it a good note I'll slap a programer in and run it on a mild tune with my 35s and we will be good to go haha.. But yeah I get what your saying but it's the same price as the single 3" or the 2 1/2 so I just can't resist it
