Flowmaster
 

I just ordered a flowmaster super10 for my 5.4. Does anyone else have this muffler and do you like it thanks?

I just did the same thing. It's going to be delivered this week. I did a lot of research on it, and it seems like the one to go with if you like loud pipes.

That's exactly what i was thinking. Let me know how you like yours.

I just had mine installed last week into a 3in exhaust from the y pipe back and it sounds awesome! I'm so happy I went with it. I can't even hear the drone over my tires on the freeway and when you give it gas it roars. You won't be disappointed!

Im obsessed with it. I got the single i. Dual out and put it straight out the back. Then i ended up taking off the pipes and putting turn downs on the muffler. And i became even more obsessed! Im really a fan of the way my truck looks without seeing any exhaust pipes

Welcome to the dark side....
Muhahahaha
I like dumped and downturned

That's what i want to do when i get it. Does it sound nasty with it turned down right after the muffler?

Sounds mean. Muffler shop accidentally welded the muffler back to the stock tail pipe. I took it for a test drive and I could barely hear it. He then downturned it like I wanted. Oh yeah! Drone is nothing serious and only at 50-55mph if lugging it in 4th uphill. I never got to hear it outside til lately. I was working on a jack on a dirt scraper w my back to the driveway when dad drove by behind. I jumped! He was just above idle :)

Im really happy with how it sounds and if ur looking for a loud exhaust then this is the way to go

Good that's exactly what i want
