Obx Headers for e90?

IB6UB9ok · 06-01-2010, 09:30 PM

How much are the headers themselves? Plus new header gaskets etc...

What's the estimated hp and tq gains on the OBX? I assume no more than 15-20hp

Anyway, keep us informed :-)

but I will cross that bridge when it comes, im waiting to place an order on them til friday, if people want to jump in with me I can offer you a better rate since I get a better price the more units I take.

~350$, the sims are on top of that.. 15hp is a lot of power for us lol

BMW power is always expensive. You do the maths..

335 - 328 = 70HP

I think it works out at $100 per HP.

Gavin@MMW · 06-02-2010, 11:35 AM

1400 is too much for headers, check out the NA vendor section and see whats up

335 to a 328 involves more than just power increase.

Why do you need O2 simulators? O2 sensors are located on the OBX headers as on the original manifold before the primary cats.

because it will throw a code without the cats.

OK, I thought that the secondary sensors are located behind the secondary cats. I just checked and I was wrong.
Any recommendation where to get the simulators?

Gavin@MMW · 06-03-2010, 12:19 PM

From me

lol

Classycali · 06-03-2010, 01:00 PM

Does anyone know if a secondary cat delete help in power or even sound? Since the headers will delete the primary cats, i mind as well remove second also. will doing this cause me to fail inspection?

Gavin@MMW · 06-03-2010, 01:04 PM

you wont smog without the cats, so the secondary cat are just gravy, cut them or leave them. Either way with headers you wont Smog.

Hello all this is my first post in this forum. I just got my 325i at the auction about a month ago. I've been a turbo Volvo tuner for over a decade and this is my 1st BMW. I'm excited to start modding it. I had a OBX downpipe and exhaust on my Volvo. It was great sound wise. The welds look a bit primitive but they are solid. I ragged on that car hard I was pushing 350 whp. OBX products are solid.

turbodrive · 06-06-2010, 10:09 PM

I'm going to purchase the OBX headers from ebay and craven i'll be needing the o2 sims please. PM me

Gavin@MMW · 06-06-2010, 10:15 PM

turbodrive · 06-06-2010, 10:21 PM
