Hey everyone I have a 06 5.4 s crew and I want to do 3" piping dumped in front of the back tire with a 4 or 5 inch tip. I been debating on the 40 series or the 44 series delta. Can't make my mind up appreciate all opinions thanks

 

I have a flowmaster 40 series welded in place of the stock muffler then dumped right after the rear axle w/ no tip or anything. it sounds ****ing great! love the sound. loud when i get on it and mild at idle and can barley hear it at 65.

 

I've heard that one idk about the delta series, I mainly drive all freeway so that's sounds like a good idea

 

I like mine.. tbh I have no idea what the shop installed lol but it's a SI/DO flowmaster and it sound nice.

 

I opted for the 50 Series and dumps right behind the passenger door in front of the rear wheel. Love the sound!

 

be a man, flowmaster super 10!

 

Flowmaster 40 Series, turned out in front of rear tire, 5" tip I'm whoring this video out, but here is my setup. It's LOUD. Sorry for the long narration lol

 

I have a cherry bomb extreme with a dual tip

 

Sorry posted before I was done.... I love the sound used to have a 40 series but this is way louder but I do have alot of cab noise on the highway ..... But the 40 series are IMO the most popular aftermarket mufflers used there is something to be said about that

 

I also have the 40 series and love it! just enough rumble on crank up and idle, great sounding on take off and quiet at cruising speeds!
