Tegiwa manifold

[kitch31]

strongly thinking of gettin the 421 manifold for my b16 but not sure whats best route to go for rest of the system currently a standard system with cat and just a apexi backbox.

iv got one and cant fault it in any way, its been on the car a year now, never been mapped or rr'd but decent power increase due to a .2 drop in quarter mile times with this fitted. and i have an under axle exhaust which hits off the road, so that would be tugging on the manifold every time it hits, and it hasnt cracked yet, and im not using the rear support either, this is the only complaint i have, tegiwa really should supply an adapter, i have proved it isnt absolutely necessary as it hasnt shown any negative results of not being supported at the back, you would feel more comfortable if it was, but must say cheers to tegiwa for making a decent affordable manifold,.... now please make one that fits my euro R,

Not sure how much help this will be as it's not a before and after comparison of the Tegiwa manifold vs another brand manifold but nevertheless the Tegiwa exhaust manifold performed well on a built b16a with ITB's that I mapped recently.
