As the title suggests, seen these on Ebay at approx £220 plus postage. Any one had any experience with either of them ?, are they worth the money ?, which of them is the best option ? etc.

 

If you do a search you will see that they normaly get a good rating, especialy the price !

However if you check out my post, "Anyone got Megan headers" You'll see that these particular ones don't have the usual Megan logo !

The seller has assured me that they are however the genuine artical, they certainly look well made.

I personaly would'nt go for the equal length XS one's though, stick with the Megans !

Probably worth the money as they are so cheap.... but remember you are dealing with a 'cheap' product here, don't expect the world!!!!

sorry slightly off topic, but what difference does equal and non equal length headers make ? as all of them seem to say they give the same power gains.

 

equal length loses the impreza's flat four engine note, sounds more normal. no warranty with these either.

 

is that the only difference ?

 

AFAIK

 

Removed drivers side heat sheld today off standard subaru header since had split at bolt and was rattling away... exhaust rusty as hec...well think you get the idea? So was also looking at EBAY
http://cgi.ebay.co.uk/ws/eBayISAPI.d...MEWA%3AIT&rd=1

IF I went for these would the car need to be RE-mapped..if so WHY
read on one site..about reset ECU by dis connecting battery....other POSTS recommending re map to get best poss performance.

what damage if any would be caused if just fitted the headers....no remap..?
new to scooby's so any advice appreciated...
cheers

 

When fitting headers due to the improved flow over the Oem unit (normally about 4k -> ) you could find the ECU may move into areas of the map that are not normally used so you may be running too much ignition advance/or not have adequate Fuelling to accomodate the additional airflow which may result in DET

Cheers

 

cheers delboy..straight to the point and a perfectly good reason why an ecu remap...MUST be done.....
think will have to wait..since remap AND headers puuuuuushes up the bucks....kerching !!!

 

I assume that will also be the case with an sti 3 ?

Also will the car have to be remapped if a de-cat (downpipe) was fitted ?

 

The same will apply with the STi3 with regards to headers - don't get me wrong, headers do reward with significant improvements but on a standard ECU there is the possibilty that it will upset the loading due to the additional airflow thus move into areas of the map not normally used. It could also upset the boost control as the turbo's characteristics will also change.
A decat downpipe on its own or with the rest of the exhaust can be fitted without a remap.

With reference to headers, ive been doing some research on them as im looking to change mine and i wouldnt but a set from ebay. Andy.
F has run a set of these for a bit to test them and had dramas. Cant remember what set they were but if you go the his website i think he tells you there. Or send him a pm.

And from what i gather, equal/unequal headers differ in more than just the note they produce. Was reading a thread on here last night about it and theres a more technical difference between them. Something to do with the balance in the engine.

Personally, i wouldnt use anything from ebay unless it had been tested on a dyno to prove bhp claims or used for six months by someone to prove reliability.

 

After hearing a few bad reports of them cracking ect I'm now considering getting my current oem headers ported and wrapped by Harvey. You do pay for what you get.

 

The headers that Andy F had problems with on the flex joint weren't Megans though were they ?
I havn't heard of problems with Megans but plenty of problems with leaking uppipe joint on headers such as Gruppe S.
Is it OK to wrap the OEM headers ?
Thought it wasn't advisable as they're cast and therefore could crack.

 

Anyone wanting the std headers off my ver.6 type r v.ltd in 3 weeks give us a shout. Also have the original exhaust inc. cat.
