Who Wants Headers for Their 2009 328i's? - BMW 3-Series (E90 E92) Forum

Skywagon · 06-16-2009, 03:35 PM

All,
I think the 2008 328i's have the same problem but I am uncertain. Regardless, as you all know, no one on the face of this earth makes tubular headers for the 2009 328i's. I've asked numerous experts and searched for months with no luck. I'm attempting to get a local speed shop to entertain the idea of using my car as a mock up and then produce them. At this point I have no idea of cost. If I can show there is a market out there maybe I can get these gents to bite. Right now they are in the "thinking about it" mode.
I have an LET ECU flash but it is being stifled by a "Service Engine Soon" light which, I'm being told, is probably canceling out the flash due to a cat delete I did. See below dyno and pictures. Darker brown plumbing is where the cats used to be. I gained 14 HP by just removing the cats. I bet I could get another 10 with real headers. Also, I have people working on the light as I type. Warning, if you want noise remove your forward cats!!
Thanks

Headers would be cool if the price is right. But I still have 20k miles left on my warranty so serious mods like this will have to wait

doesnt supersprint make them? eventhough the price might not be right

Skywagon · 06-19-2009, 02:10 PM

Supersprint does not make them for the 09's. I called and asked. I'm going to talk to my local folks again next week and see what price range they may be in.

How does it sound different compared as Stock! Very? high? slightly? barely? even?

daheechang · 08-24-2009, 02:15 PM

if it still works on teh 06 330i's i'd be down depending on price.

Read this thread before you waste time and money developing these headers:

They don't think it's worth putting a header on the car because the stock manifolds are so good. And they're a race team.

The guy on the link uses the stock header without a CAT, and we are talking about the CAT in this thread

No, he uses the stock header because they didn't find any advantage to using an aftermarket header. He said the stock one is really good and no need to change it.

You mean that there isn't any power advantage even with a CAT? that's very good info tho!

Awsome numbers from your primary cat delete btw! 15 hp (185.2 -> 200.5 hp) just by deleting the front cats, thats monster!

You must be the first guy to do this, I like how you showed the inside of the cat after you cut it off:

As for your error light, I think you can resolve that issue by getting an o2 simulator.
