I spot Supersprint Headers & Cats at an insurance impound east of Ottawa similar to this photo part number 789001 and 789002.

My questions are:
Will those parts fit my other OEM exhaust parts perfectly without any welding or cutting?
Has anybody here ever successfully installed those two parts in conjunction with their other OEM exhaust parts?

Theoretically, the E90 wheelbases of 323i, 325i, 328i, 330i and 335i are all the same 108.70 inches or 2760 mm so those parts should fit perfectly (IN THEORY).

Any comment, suggestion, pointer, something to say in general????

Thank You

def void warranty tho.

you`re on crack if you think a full supersprint exhaust costs 20K

there is no reason why headers would automatically void the warantee. There would have to be proof of the problem being caused by this change.

The biggest issue is getting software to make it all work properly.

Oh I think I got it mixed up with arqray
Or... I dunno

Yeah pretty sure you don't need software for headers. I mean it might help get a few more hp out, but definitely not needed by any means.

Technically, I should only pay $451.34 according to that salvage place.
Whoever previously owned that E90 325i wrecked that car badly that the insurance company wrote it off.
Also verified with Mr. WT of TMS that no software update needed.....

Any thought before I cough up $451.34 for slightly used Supersprint components and around $400 labour fees to install those things?????

have you asked TMS or someone else if this supersprint header will fit your car? Seems to me like it may not fit due to the engines having different bore sizes.

As for the software, sure you don`t need it. However, don`t be stunned to see a check engine light show up unless you move the O2 sensors corresponding to the primary catalysts down to the other cats or replace them with O2 simms!

If those parts fit your car, get them. Thats a bargain.

i think you will get check engine light for sure. i think 2 other guys on this forum tried using the SS headers and got a cel.

yeah... he will get CELs for sure unless he gets O2 simms, relocates the current O2 sensors (may still get CEL), or, unless the software gets told that the new exhaust readings are correct (ie. with new software)

i have SS headers , you do need a software for the car to work properly

[clairvoyant]

Does your header fit other OEM exhaust parts perfectly without any welding or cutting (otherwise plug n' play)?
Do you get any check engine light error in any kind?

Thank You

what changes did you notice from stock with the SS headers? In terms of sound, noise, power, droning, etc.?

[clairvoyant]

Also what kind of software do I need?
I consulted with folks at Turner Motor Sport; they said no software required in my case since my 323i has the ECU upgrade of 325i.
I could be wrong.

Thank You

Well the first change thats very noticeble is the sound, its a bit raspy at lower rpms, but sounds amazing when you get to red line, power wise it feels like it got low end torque and high end horsepower, and no droning. but here is a thing, im driving with the CEL on, because with my setup im catless (SS headers, Eisenman SR pipes welded to Ikon muffler and afe intake) my car burns rich, and outputs less power than stock( i dont know the whp number loss) but this is what i read, anyways thats why i need a custom tune for all my mods to work properly, and of course to produce greater numbers than stock again i dont know how much greater. there is nothing really out yet but there is a local shop that suppose to get new software, that will allow to custom tune my car on a dyno, the guy said somewhere by the fall, so im just waiting. oh and here are some crappy videos http://s169.photobucket.com/albums/u...t=MOV00338.flv

i guess if your CEL doesnt appear than you should be fine( the car wont burn rich and should output more power than stock), but as i mentioned before you need to tune the car, for it to work to its max potential

How do you create/use an O2 sensor simulator?
Thank You

[audiprotein]

Either you gotta move the o2 sensor somewhere farther or make it stick out more...
But in BeMyWife330i's situation it didnt work out.

people sell O2 simulators that basically simulate the signal from an O2 sensor that is providing the correct numbers to the engine computer. This tricks the computer into thinking that the emissions values being read are correct and you therefore, in theory, don't get a check engine light.
