Tomei Equal Length Exhaust Manifold Subaru WRX 2002-2014 / STI 2004-2019
Tomei designed the headers to be the 4-2-1 layout with 42.7mm, 45mm, 60mm sizes to help extract the absolute maximum from your EJ25 turbine with the equal length design. The exhaust pressure is controlled best by this layout and you can see the peak power gains at high RPM.
The lost wax process was used to eliminate cracking from welded weak points and for aiding smooth exhaust gas flow with out any interference.You will have a new higher pitched racing sound from the isometric design. With 2.5mm thick pipes made from SUS304 Stainless Steel.
Header is well manufactured. Welds are beautiful. It was nice that the wrap came with them. Perfect fitment.
Bought this header for my husband. The wrap that was included was awesome and so easy to do. He and I got it done in what felt like 10 minutes. Header itself sounds amazing in my opinion. Happy with the money I spent on this!
In my opinion these are the best sounding and best bang for your buck there is. A 3 bolt is a must, extremely high quality header! Even came with exhaust wrap and ties and man does it look beautiful!
Hands down the best headers for the price
I was very happy with this product. The headers a high quality. I was very disappointed when I went to mount them up to my 2002 wrx though. I was never told or saw it anywhere on this site that you have to have a 2.5 liter oil pan and pick up tube to make the equal length headers fit. So that was very frustrating and inconvenient and costed me hundreds more to make these fit. I would recommend they list these as ONLY fitting 2.5 liter cars.
