Ecoboost down pipe

You've got to remember that it has 2 high flow cats in it. I'm imagining that's where a lot of the back pressure is being freed up. Those are usually around $200/ea from Summit. So $700 for the system really isn't that bad. After I get my tuner that's my next mod along with a high flow mid cat. Then I'll probably be done with mods on the truck.
If there are no O2 sensors after the 2nd cat, I'd much rather see something that deletes the pre-cats entirely.

putting bigger turbos on is the easy part. Getting more fuel will be the challenge. Designing new HP pumps to support extra boost. What are the limits of the stock injectors? How long before companies start making bigger injectors to support switching to e85 or bigger turbos/more boost. I could go out and weld up some piping and flanges then bolt bigger turbos to my truck even if I had the ability at the moment to make the pcm believe that the new set up is all well and good, I don't think the fuel system will support it.
I would suspect that the direct injection system on the ecoboost should also be able to handle significant power gains.

That's impressive, but It's BMW, based on the Mazda performance stuff the hpfuel pump needs to be upgraded relatively soon. Then again it could be the opposite, so whoever runs out of fuel first on the dump will figure it out.

I would love an O2 dump downpipe for my eco. Why hasn't anyone though of this? With everyone complaining how their catback doesn't give them the "mean" sound they desire, i think an O2 dump dp would be a hit. My .02

The Flex and SHO guys seem to be running out of fuel with stock turbos turned up, I also had an Mazda MS6 and they did run out of fuel early as well. We'll see with the trucks but I'm definitely interested.

MBRP CAT Delete
we have done several trucks at our shop with either the high flow cat doenpipe or the cat delete pipe. We have had no issues and good response. Without cats we are avergaing an extra 22hp and the pipe is about 500.00.. with SCT tuning the trucks really respond well....

Stainless really isn't that expensive though (my dad sells the stuff), and I doubt they're paying retail for the cats. My Bassani x pipe I put on my Mustang 10 years ago was right around $400 and used more material, so yeah, they're a tad high.
