Description

TEGIWA Race 4-2-1 Exhaust Manifold Header.

Changing the manifold is one of the best modifications you can do to the Civic Type R EP3 and Integra DC5.

Just with this alone, gains of between 5-10bhp are achievable before mapping. With supporting mods and mapping, gains of between 7-15bhp and a lot more torque are easily achieved.

Constructed from premium 304 grade stainless steel the header features the popular 4-2-1 design, CNC mill-cut flanges, and 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. The header will fit perfectly with all OEM and aftermarket exhaust systems. Installing this header removes your cat. Including new gaskets.

 

Power gains are further improved after tuning, we have seen customer cars making very good power gains with supporting modifications from 250-330bhp.

 

Note For Integra DC5 Owners:

When Fitting this manifold it is advised to add engine mount inserts to stop forward and back rocking motion of engine, this will stop your manifold hitting the anti roll bar and improve flexi lifespan.

Please select the option above if you require engine mount inserts with your new header.
