EJ255/257 4-2-1 Equal Length Exhaust Manifold Kit by Tomei

With our ever popular EXPREME exhaust manifolds which is now used throughout the world. Our EXPREME Manifolds have received numerous high appraisals on all aspects of efficiency, durability and performance gains. Now with this new addition to the EJ25 user family we now have a manifold specifically to optimize the EJ25 true power output potential.

We designed the headers to be the 4-2-1 layout with φ42.7mm, φ45.0mm, φ60.0mm 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 & you can see the peak power gains & at high RPM.

You will have a new higher pitched racing sound from this isometric design. With 2.5mm thick pipes made from SUS304 stainless steel. The Lost Wax process was used to eliminate cracking from welded weak points and for aiding smoother exhaust gas flow without any interference.

Awesome Packaged deal

This bit of kit is awesome and comes with everything you will need including an up pipe! I used a couple of extra metal zip ties on the wrapping but smooth install thanks to the adjustable clamp thing. I did loose one of the little bolts on the clamp after a few hundred miles but that's on me for not re checking tightness after a few heat cycles. MAPerforamnce had the best price on this item and the fastest shipping.

Tomei ELH is just perfect!

Beautiful work of art, MAPerformance with fast shipping and friendly staff got me hooked up. Fitment was perfect as well no issues at all. Paired the tomei ELH with my grimmspeed 38mm EWG up pipe and tomei downpipe with the tomei catback. Sounds so amazing!
