Exhaust metal grade

[nastang87xx]

Hey guys, I've been trying to figure this out for 100%, sure. Going to do a resonator delete, the factory exhaust is 409 stainless, right? Called Ford Performance, they weren't exactly sure.

Yes 409SS. You should consider replacing the x pipe as well. The restriction before and after is considerable as well as the x pipe itself. Both measure around 2.35" while the x pipe itself is 2.5" with the remainder of the tail section at 2.75". The midpipe is all 2.5" as well as the short section behind the mid-pipe collar clamp. I can certainly see why the aftermarket is picking up 18hp or so with just an exhaust change.

X Pipe without aftermarket headers

Is there anyone is making an X pipe that you can use without replacing the headers? I have not been able to find one? With Kooks you have to use their headers. Thanks for your help!

I am betting this will work. One and done! Replace the x-pipe and delete the resonators. Someone needs to be the guinea pig.

It's a great idea...but FP was emphatic that it will not work.....bummer, thanks anyway!

What was their reason? The exhaust diameters are a match. That leaves the spacing and the length if long enough after the x-pipe to replace the resonators.

 

[bobmclean]

The X I believe is tighter on the 350 than the GT?

Spacing would be easy enough to tweak if necessary. That leaves (as you said) length.

Then again, that is one ugly looking X assembly from Ford Racing. Stevie Wonder should not be welding on the side for a few extra bucks.

Agreed, that thing is hideous. You can get a universal x-pipe from magnaflow for around $100

I don't think there is much to be had replacing it, but hey it looks nicer!

I agree Tob. Wouldn't be the first time that Ford used a prototype for their picture. Any pics of one received by a forum member for their GT?

I've never had one Magnaflow product that fit my car right two Magnaflow Comp systems and a cut and clamp X pipe and one of my Maggy Comp systems blew out. I've been through products from Kooks, Borla, Stainless Works, Ford Racing, and Flowmaster and never had a problem with any of those. Never again from Magnablow. I'll just be cutting and welding, a friend is doing it who has a shop and he does good work.

Yep. It's the cheap shit. 409.

 

[cjgt350]

I don't see why this would not work. The weld looks much better in this video btw.
