Hey I have a 1998 Subaru legacy with the single port ej22 and I want a good Subaru rumble but I can't find one for my car. 🆘Hi everyone, thought I'd show you what my friend and I have been working on.
We are currently making a prototype ej22 single port header that we plan to produce and sell. The prototype Header features CNC plasma cut 3/8" flanges, mandrel bends, our own Collector/Diffuser, 1.75" 16 Guage Primaries and Tig Welds all around.
In the future we will be offering these in Mild steel with a few coating options, or 304 ss. The prototype is of EL design and currently has 39" and 35" primaries. When production begins we will have the Headers Equal Length +/- 2". For all of you who prefer a nice rumble, we'll be offering a UEL design as well.
As many or you know the stock collector for the ej22 is absolute garbage and is one of the main choking points in the exhaust. Our collector solves this problem and Improves scavenging effect through the primaries. Another side effect of proper collector design is that regardless of the EL or UEL design, both Headers will have excellent performance gains. Here is a comparrison between the Collectors for all you visual learners.
Currently my colleague is home for Christmas Tig welding the headers. I'll be posting updates in this thread such as quality pictures of the final product and sound comparrison. In the meantime here's a set of headers we made for a f4i engine.
