Anyone added aftermarket exhaust?

[TheDoug]

I was curious if anyone here had added an aftermarket catback to their expedition. Looks like the only kit I can find is the magnaflow one. Is there anything else out there?

Magnaflow are HORRIBLE for nasty drone! Be careful what you sign up for. Typically Corsa is the non-drone option!

I can't stand the non stop drone all my previous Magnaflow's had on my other cars.

Corsa is way too harsh sounding. Magnaflow on Ecoboosts are good only if they are straight thru design. Any chambered muffler on a turbo is a no no. Go look at the F-150 guys putting corsa vs magnaflow. Corsa gives you a ton of Drone because of how aggressive it is and magnaflow is definitely more mellow. For starters, I would try doing the rear resonator removal and see how you like that sound. I played with my exhaust a bit and everything I did made it sound shittier than stock. I stopped with the rear resonator removal

With only 3.5L I would't ever expect it to sound good. Its just a V6.... Sounds like an old Dodge K-Car with the muffler dragging lol.

I realize it's not a v8 but I was hoping for just a little more of an aggressive tone. I heard some clips online of the f150s with the 3.5 and the magnaflow sounds about the right level for me but I am always worried about drone in cabin.

They also keep the OEM resonator on the f150s also

Good to know, thanks

I might hold off on any exhaust upgrades for a while then... think I will upgrade the intercooler first.

I recommend doing the IC and all cold and hot side pipes. I’m getting the mishimoto for my 16 with the pipe kit next

Could always do the downpipe and leave the rest alone.

Thts even worse

Sound is such a subjective thing. Take 2 people, play the same high end home or car speaker, one loves the sound, the other thinks it's too forward or too weak. Same for exaust. Your going to need to visit a few different custom exaust or tuner shops. Hopefully they have an F150, or Expedition that you can hear. Or they can call you over when their doing one. That's what I'd do. Whenever I had a car or motorcycle that I wanted to change exaust, I'd see a guy, and ask him what he had, how's was the power, sound, and any losses and where. Remember every exaust change is going to have pluses and minuses. You need to do your homework. A lot less disappointed that way. Problem with exaust is it's usually a welded up deal, with no do over.

Go over to 5 stars FB page and request an add and just search “exhaust” and look at all the videos those guys have. They post ALOT

Just remember we have the DPs that dump straight to the flex pipe and muffler then several feet of tubing to a rear resonator. F-150 guys have DPs that dunk straight to a resonator, couple feet of pipe, a muffler, and more pipe to the end. Where the muffler is placed will have an effect on sound and power

You do a DP on stock tune and you will lose a ton of low end power. Tuning it is the only way to fix that

That or a supercharger! When we used to build 2 stroke expansion Chambers for our Yamaha single and twin cylinder race motorcycles, just a different bend, or making the main part of pipe before stingers, shorter or longer could make either an improvement, or loss of power. Keep in mind back in the 70's we did it seat of the pants, and with recommend sizes from other racers. Raising or dropping ports by grinding also made huge horsepower and torque difference. These days you guys are lucky, reprogramming a computer does what hours of work and parts used to.

Or wait for the Borla. Thats what I do...

Thts just as aggressive as the corsa, just not as raspy. But you’ll sound like a Honda

Already have a tune.. not my first EB but I've also never done an exhaust on the previous ones because they all sound like crap. So yes with a tune, I'd most likely do catted downpipes and stop there.

SPD!

THe borla will be the mildest version, no stinger or attack, so it should be quite mild....

Always thought the Corsa sounded good.
