Thread: Developing Headers

If it's not under $200 and they don't install themselves, they probably will not sell mass quantities. Maybe if it were 7 years ago there would be more of a market, but not these days.

But the primaries would probably be 1 5/8ths and 1 3/4ths max, keep the rear header and crossover one piece, leave the lower downpipe flange in an easy access spot and v-band. Also put the 02 sensor bung on the crossover near cyl. #6, the values will be the same from the front bank to the rear bank and very easy to access. Possibly leave a bung for wideband. 3" downpipe with direct bolt on to factory catback. Also if you could upsweep the primaries that would be awesome.

The $200 SpeedDaddy headers seem to be what everybody wants since they are stainless and cheap. If you could develop headers that were superior to those and close in price, you could have a winner. The problems I have seen with the SpeedDaddy headers are the sink trap in the down pipe, the flex section is cheap (should be an interlocking flex) and the crossover does not line up well. I agree with Bio that the S&S design would be a good one to copy instead of the SLP headers that SpeedDaddy copied.
