I asked Rob in pm and here is the answer :

I can certainly help you out on what parts to run for stage 2. Initially there will be two maps released.
Stage 2 - Designed to run a turbo back exhaust and stock FMIC.
Stage 2 + FMIC.

hope this help !

[Devas]

Stage 2 + FMIC, mean you need FMIC and a Turbo Back exhaust?

[Zasquatch]

I would think on our cars a full exhaust is not necessary, but downpipes are mandatory. There are a bunch of threads showing people getting minimal gains from a full exhaust with downpipes vs. downpipes alone.

To me the list reads:
Stage 2 - Intake, Downpipes
Stage 2+ - Intake, Downpipes, FMIC

[Devas]

Haha where did you get "Intake" from that list?

I hope you're right about downpipes and not full exhaust, cause i still want my car to be quiet.

LOL I took some artistic liberty... intake, dci, drop-in, Mr. 5, pick your poison...

[Devas]

From most threads i've seen here, intake didn't make much of a difference.. But I'll go with COBB stage 2 requirements, nothing more and nothing less.

[Frampton]

i would bet that stage 2 will not require an intake...

we dyno'd my stage 1 135 at COBB austin and measured a drop in hp across the board with almost brand new bms dci's compared to a brand new filter in the stock airbox, and just for fun we popped the hood and took the cover off the intake and measured marginal gains over the factory airbox. There just isn't a lot to gain out of an intake on this car imho. At some point i'll dyno stock vs an afe vs aftermakert drop in filters.

on another note, get a full exhaust and a front mount for stage 2. The stock front mount is really struggling to keep IAT's down even on stage 1. I see nearly 170 degree IAT's on the track with stage 1... There is no way you can move to stage 2 without a FMIC imho...

Good luck with that; they won't make pulls in 4th and my car just spun on the rollers in 3rd so it's been difficult at best to illustrate gains with the tune and supporting (er, complimenting) bolt-ons.

Yeah, I agree that it doesn't make much (if any) power, but it does lower WGDC which is a good thing for turbo longevety..

That being said, let's see what cobb says, but I would think stage 2 would be DP's and FMIC.... I see no reason to say a full exhaust is mandatory.

Thanks for the info. Glad I left my DPs in.. Now time for that BMWPE

[Devas]

The BMW PE won't make the requirements, you need Turbo Back

You think COBB will offer hardware for us? like they do with most of their cars? If so i would rather buy theirs. I rather stick with specification that was designed for their tune. So they could help me troubleshoot if such events occur

[rader1]

It would be nice to hear a little bit about some features to expect, infact it would be nice to hear anything directly from cobb. They were strong and all over the board when stage 1 was released, but they've all but disappeared. To be fair though, with no new products there shouldn't be a whole lot of new questions to answer. But it would be nice to have continued access to suport on the boards.

I was told by a little blue birdie (COBB), that they have been less than impressed with downpipes that are on the market. Their build quality and power output isn't in question, but their fitment on general is not good. There were thoughts amongst the staff they could do better and they were looking into it.

But from the way the story was told to me, I don't believe this is anywhere on their current product roadmap.

[Devas]

Hmm i thought the ETS one is was perfect fit?

anyone knows if stage 1 has speed limit delete?

The mid section, crossover and mufflers of the OEM (and PE) exhaust system is not significantly restrictive. "Turbo-back" implies everything is gutted for aftermarket and/or larger diameter piping, which just isn't necessary at the 400 WHP level.

I've also heard they are interested in offering hardware upgrades but those components are much farther down the line.

[Devas]

I meant that PE exhaust won't do anything, you need down pipes.

THIS....

After i installed my HPF FMIC the IAT temps barely goes up pull after pull. Upgraded FMIC should be required on any tune IMO.
