My wife and I just picked up her 2011 F150 SuperCrew today. It has the 5.0 in it. It goes in to the shop tomorrow for a dual 2 1/2 in exhaust into a dual inlet/outlet magnaflow muffler 90ed behind the rear tires. I will post videos after its done.

 

Sweet.

 

Make sure that muffler has an internal X-pipe. Be sure to post vids, lots of vids.

 

The muffler does have an internal x pipe. after going to the exhaust shop they said the can't modify my factory exhaust before the y pipe to run duals. i called the local ford service center for clarification and they told me if i modify the y pipe it will void my warranty. I reordered my muffler for a 3 in single inlet dual 2.5 in outlets, should be in by tuesday next week. Side note: only reason i am ordering a muffler is because the exhaust shops in hawaii only seem to carry flowmaster, dynomax or borla and I wanted a magnaflow muffler. I will post videos as soon as I can get it done

 

Yes...

 

They'll void the entire warranty or just exhaust related warranty issues?

 

Can't wait to hear this beast!

 

they were vague on what or how it will void the warranty. i ordered the new single inlet dual outlet muffler 2nd day air from summitracing. It should be here tuesday and the truck will be going in wed. I love the growl the truck has stock, but am dieing to hear it with a set of pipes.

 

I like how the stock system sounds too. Really gives it character.

 

UPS dropped off the muffler tonight at 9pm. The truck goes in tomorrow for its exhaust upgrade. Using a magnaflow muffler single 3 in inlet and dual 2 1/2 in outlets 90ed behind each tire. I will post videos afterwards.

 

Cannot wait to hear it!!

 

I think this is his video?
