Hello, i just purchased the hamann exhaust system through HSU and will be installing them onto my 330i shortly. I want to also buy and install the supersprint headers onto this system. I did look at all the forums that came up from teh search and find out that the CEL will go off and heard some suggestions on how to take it off, but has anyone on here actually achieved taking the CEL off using the SS headers? Pics will go up once i do get them installed, i just wanted to ask if anyone had any luck w/ getting the CEL off. I know Tecknik installed these as well, but didnt hear whethe he was able to turn off the CEL. thanks!

also some otehr mods i will be installing within the next couple weeks :
Kerscher front bumper w/ cf lip (thanks to johnny lin)
Mtech rear bumper
Hamann quad exhaust (thanks to HSU)
Euro xenon adaptive lights (thanks to HSU)
PIAA angel lights (thanks to HSU)
OEM rear spoiler (thanks to Johnny Lin)
H&R sport springs (will be installing on my current oem sport suspension, hopefully will be durable)

Also, if anyone is interested, i will be selling my Eisenmann SR pipes w/ roughly 600 miles on them only. shoot offers. will be up for sale as soon as my hamann goes on and the eisenmann goes off

nobody has experience with hamann or supersprint setups?! any help would be great

Has anyone succesfully installed headers onto their 330i without the cEL coming on?

[Not Ur Avg 3]

i have a 325i...
u and me are the only ones known to date with SS headers...
i got mines from hunter, n there sweet
i also got the RT high flow cats along with the headers, and put those in...
i was originally gonna extend my o2 sensors, and basically trick my ecu, but i didnt wanna waste time on that
so yes i currently have a "service engine soon" light, and its annoying nonetheless, but harmless
im workn with my friend at his shop, and im waiting on this company to finish up there 325/330 software, and am just gonna get that, and have it tuned to where the ecu think i have NO cats at all, and will result in NO engine light.
im still doing some research on the software, bcuz im also going to do the 330 conversion with the manifold n all that, but ye, ur best bet is to get software to lie to ur car essentially man.

but the end resulting sound, is worth all the damn engine lights in the world

if u really want no light tho, just when u install them, have them extend the o2 sensors further down ur exhaust and u shud be good....

[daheechang]

thanks so much for the response! yea i'll try that when i get it installed. Do you feel some decent gains from the headers?

[whitecord]

try these i have heard good things about them. not sure if they will fit perfect. but you can try. this way you dont have to do any wire extensions!

next option would be to find a o2 simulator that would give a good enough signal to the dme to trick it.

[daheechang]

wouldn't wire extheniosn be easier or even cheaper?

[daheechang]

thanks for the input though!

[daheechang]

has anyone been successful in using these headers w/o the CEL on? still haven't had anyone tell me if tey had

[jjhan85]

YO can we get a sound clip of the SS headers??? im dying to hear how it sounds...also...you feel any gain in hp with them headers?

[daheechang]

i'll post as soon as they get put on later this week

[daheechang]

haha i've searched for like 4 months now and still haven't found a definate answer to this.. can anyone w/ past experience help me with this please?!!?
i found this thread on another forum, but not sure if it would do the same w/ our e90 330i's.
http://forum.e46fanatics.com/showthread.php?t=348277

i've also had input from fellow forum members but just suggestions and nothing from direct experience. if anyone here has fixed this please chime in, i'd love to install my headers and cats!

[HSU]

only SS front pipe with cats can take off CEL

[Willstophe]

I want to get SS headers and my current setup is as follows:

RD Sport muffler with secondary cat delete (Basically a muffler with strait piping), 3-stage intake manifold with stage I 330i software, and Dinan Ram-air Intake with RPI scoops.

My main concern is performance gains. Will I loose power/torque by installing these with my setup?

have u take your car to dyno test?same output with stock 330i?and stage I 330i software,which mean they have stage II or III software?interested to do that too.will these cost much to do this mod?thanks!

[Willstophe]

I don't know where to dyno the car to begin with. I want to. I have the manifold on and the software loaded and the car is substantially faster too. There's this place in Irvine that wants 80 dollars to dyno the car and I'm like...dude...80 dollars for a dyno...no thanks I'll take my chances else-where...

for the 330i software.u have to replace the whole software or just do the reflash or download to current computer.also,how much did u spent on this mod.?

[Willstophe]

I spent 650 on the manifold itself. Each Actuator was another 180. And the bolts and screws for the parts were 75. As for the software: it would've been 800 but instead I got a refund for my DTE and used that as credit so that part was free. The install was 1k. Autowerks in HB did that. I recommend getbmwparts.com. I wish I knew about them before I purchased. They were selling it for 450. About a 200 dollar difference. And it's strait from the factory so you know it's good.

[Willstophe]

But ya back to the headers question. Does anybody know if with my setup I'd loose power? I want to get them so bad but I'm still skeptical. I'm also going to have a second muffler made by RD Sport and do a dual twin-pipe setup.

[clairvoyant]

Would you knidly run a diagnostic and tell me the EXACT error codes of your Check Engine light errors?
Thank you

you will not lose power anywhere! Look at your other thread... the only question is how much gain you will get and where in the rev band.

Also, just so you know, 80 dollars for a dyno run is cheap. Usually places charge 100 dollars.
