I just called Magnaflow today and an exhaust system is being test fitted now. They should have a system for us EcoBoost guys in 6 to 8 weeks!!!!!

There are mufflers that fit now if you don't need the whole cat-back thing - http://www.fordflex.....php?f=7&t=2263

I'm a die-hard Magnaflow customer, so I've looked into the cat-back system for my 2010 SEL.

Unless you're turning out 400 to 500 HP, there's no sense in spending the money on a mandrel bent, cat-back exhaust system.

I just got done replacing all the stock mufflers with a Magnaflow 4"x9"x14" in the rear, and a 21" resonator in the front...and it sounds bitchen!!!

In doing so, I saved myself $300.00!!!

Do yourself a favor...find yourself a good muffler guy, and they'll be able to hook you up like mine did.

The reason I install cat-back system is to retain the stock pipes if I need them. Also, any modification to California exhaust systems without a Carb E.O. number will fail smog. That is the reason for that, plus if I don't like the sound I can always change it back. I have never been much of a V6 guy (My other car is a balls out 347 91 Mustang LX).

Would the cat back system for the 2010 ecoboost flex thats listed on the magnaflow site fit on a 2011 ecoboost?

I would say that Eco Boost exhaust would have to be different than the non turbo, these guys show the eco boost system available...

I see that Magna flow now shows a cat back system for the eco boost Flex Now I just need to decide if I want to put it on my flex when i get it...

Expect marginal performance gains from a cat-back exhaust system unless your purely in it for the sportier sound. Exhaust flow will still be restricted with the cat in place. Larger, mandrel and/or free flowing exhausts help with keeping the exhaust gasses flowing reducing spool on larger turbos. Last I looked, the turbos equipped on an Ecoboost are Garret GT-15's. They are small and don't require a lot of exhaust velocity to get them into spinning. I notice with the stock exhaust that there is marginal lag..

I am going to try a water/meth injection system. Seems pretty popular and I have friends that use it on their turbo projects with great results. I know with Volkswagen direct injection motors (2.0LFSI) there has been excessive carbon build-up on the valves. Water/meth injection helps with this along with the performance gains.
Maybe an aftermarket intercooler set-up with a larger and more efficient core and better flowing IC piping?
And if your budget is larger, custom tune, bigger injectors, increased fuel pump output?

Actually... while I was working with Scott from MRT, developing an axle-back kit for the my Flex EB we cut open one of the stock mufflers.. OMG!!! Talk about a CORK!!!

Half the stock muffler is jam packed with fiberglass:

And how do the gasses flow... the outlet tube is quite a bit smaller than the inlet tube!

and when I say jammed packed...

We picked up close to 20 HP with the MRT axle back over the stock mufflers...
