Tri Y headers..

Small tube will work work with b16a. With the B18c7 and B20 definately go for the big tube design ones. Gains everywhere over the small tube!

With these tri-y design headers on b16a it'll hand 7mm lower then b18c blocks.

just wanna ask is there any diff between the 1 piece extractor and 2 piece extractor?

Oh ok just to confirm to fit the replica tri-y regular tube... we don't have to remove a/c and we have to cut our b pipe in order for cat to fit and also cut into the cross member?

hey guys, just put 1 on my car.

lose some low end power.

quite alot of gains up the vtec range.

the above based on butt dyno, no real figures to support my stand.

makes the engine sounds raw.

makes engine check light come on ( hopefully this wld be solved soon )

don't have to remove a/c to fit in.. just a pain in the arse

yep cut b-pipe because the secondaries on the tri-y are generally longer

no need to cut into anything.. should fit underneath
also if running a b18c7 you'll need a b16 flywheel cover to fit the tri-y's under there
