Someone made something cool. Catted, so might be OK without a tune, but would probably need a cheater pipe.

And the goodies are starting to appear.....

Oh yay! I’m in for one of these. Would like to see some dyno numbers to see if it frees up any power or if it’s only a drivability change.

Messaged to become a dealer this morning!

Anyone see any dyno data on the downpipe yet?

Nope, and I don't need to really. The current one is 3" already, and I won't bother getting it unless I need to do something stupid like put a big turbo on or something. It was nice in my old car to have the aftermarket downpipe, but it was catless (the only way), and smelled bad. This one will stay stock unless something "tragic" happens to it.

I was poking around under the truck and the only real restriction I see is the 2.5” just after the stock cat. However, it could flow just fine for the turbo that’s on here but I don’t know the specs of the turbo. Do you have any info on it? I’d really like to see a compressor map on it.

I'd say it's "similar, but not exact" to the mustang turbo. My guess is compressor maps are out there, but not readily available. Internet speculation says it's the same housing as the Mustang, but with a bigger compressor wheel. No proof of this obviously.

Would love me feedback on this product.

Here's another, they have catted and catless.

Usually these down pipes have a race cat of some type, the issue is will it throw a code for the post cat and will you need a spacer to solve for the code. In addition, to get the most out of it you will want a tune that makes the necessary adjustments and adds the complete potential of the down pipe.

 

[t4thfavor]

I figured you would need a spacer, I called it a "cheater pipe" though.

I never get the "race cat" version, if I'm going to live with a reduced catalytic, I might as well reduce it to 0 and save 400$

Just threw my first check engine light, code P0420, appears to be high carbon buildup on the O2 sensor. Running AFE catted, verified the problem, cleared the code with Livernois tuner.

Can you tell me how much louder your exhaust is now. I assume you have an aftermarket exhaust as well?

It is quite a bit louder now, I have the borla S type dual tip exhaust. There is quite a bit of restriction in the stock down pipe. It also weighs about three times more than the AFE catted down pipe.People driving around in diesel trucks think that I have a diesel truck now. To me it still sounds like gas but at least 7 people have stopped to ask me what diesel motor I have lol
