Put this setup on this afternoon on my 04. It in fact made a huge difference, anywhere in 1st gear when I punch it, the truck will go sideways now, when before it would just spin for a bit and go.

The magnaflow muffler rocks

 

THIS THREAD IS WORTHLESS WITHOUT PICTURES !!! :-)

Come on, crawl under there and snap some pics of this setup!

 

 

So you took off the rear 2 cats eh?? Ford can't say anything either cause there aren't any o2 sensors in front of those cats!

 

Awesome man! Magnaflow rocks!

 

special thanks to justin, now i have a $1000 exhaust system rolling around in my head...

 

bwhahahahahaha....

and for the requested photo's.

 

Cool, thanks!

BTW, where did you put he "X", or is built into the muffler ?

 

It's built into the magnaflow. I meant to take a picture before it was put on, but I forgot.

 

BTW, here is a Stainless "Modular" Crossover (X) that I designed and build (obviously not for an F-150). With my design the customer can switch from cats to no cats in 15-30 minutes..

 

Thats a sweet setup right there. What vehicle does that go on?

 

Thanks, it is a direct bolt on replacement for the Porsche 928 stock dual cat system.

BTW, whoever did you exhaust work does nice work.

 

Most Porsches will pass emissions without the cats. Mine does, several friends do as well. Mine 'has' a cat..but someone defiled it. It's hollow, but..um...there. No idea how that happened. Still passes, even in a GT-3s way over boosted, piggy back fueled racecar and colorado emissions are the 20 minute on a dyno running through the gears etc... I do have to turn the fuel down a bit though. On several friends cars with stock fuel injection though..they pass no sweat...cats mysteriously hollow.

That's cool. So is that Muffler a generic Magnaflow product or specific to the f-150? Custom tubing or kit?

 

I like it!

How much did it set you back?
