Tegiwa TODA style exhaust manifold 4-2-2-1 2.5'' stainless steel (Honda Civic/Integra 01-06 Type R)

TEGIWA Civic Type R EP3 and Integra DC5 Race Manifold Header. At last... the long awaited manifold is in stock!! Changing the manifold is one of the best modifications you can do to you Type R. Just with this alone gains of between 5-10bhp are achievable before mapping and after mapping with complimentary mods between 7-15bhp.

Constructed from premium 304 grade Stainless steel. It features the popular 4-2-1 design, CNC mill-cut flanges & robotic rotation purge TIG welding. Being a 4-2-1 configuration means it gives both excellent mid range and peak gains.
It has been proven as being one of the best 'off the shelf' headers available. There are many dyno's with EP3's and DC5's reaching 250+ bhp with this header. The header will fit perfectly with all OEM and aftermarket exhaust systems. Please note: using this header removes your cat.
Please note: If you don't have an O2 eliminator or a K-pro/AEM/HALTECH ecu, you will need an O2 cell fix as well.

DYNO INFORMATION:

The dyno sheet is from an EP3 with Skunk2 Pro series intake (stock throttle body), Tegiwa exhaust manifold and Tanabe 2.5'' catback. Result: 221 HP
The same car went on the dyno again with a 3'' custom catback and it suddenly had 241 HP!
If the customer takes a 70mm throttle body, the HP will probably raise up to 250-255 HP.
