FS: S54 headers

[gobuffs]

Since I sold my S54 I have the headers from it for sale. They are Ebay headers that were worked to fit properly. They have a Y connector welded so that the header is one single piece not 2 separate pieces. The Y connector terminates into a 3" flange that uses a V band clamp to connect to the rest of the exhaust. You will need some custom work to connect the header to the rest of the exhaust. $500 plus shipping from 75707

Yes...however the motor was moved back 5.5" inches in the chassis to accommodate the dual sump pan.

Never drove it without them. Was putting down at least 325 RWHP using a Pectel standalone ECU.

Ebay headers generally dyno around 15-20 whp more than the stock US headers. They're probably the cheapest power you can get for an E46 M3.

Even the Euro S54 headers yield great power gains, but they cost a bit more than EBay headers. However, they are built to the same quality as the stock headers, so there are no fitment issues, which can be an issue with the cheap headers.

Check out Epic Motorsports. They have the largest gains from tuning the stock DME. Their Race tune can get you close to 325 whp.
