Tdo4l on stock mani

[stevh0]

I know the stock manifold is extremely restrictive, but how will a TDO4l fair on a stock 4efte with a 63mm downpipe into the stock exhaust?

Take the stock manifold and join a new flange on it, will it be worth the effort?
Looking for just a little more midrange...

Im going to say no, it wouldnt be worth it mate, would do more damage than good. As the 3rd runner is very restrictive...
May as well get a mani to suit mate??

parts are a problem out here. Bringing one over from Europe will just cost wayyyy too much.

port out the manifold a bit and it will be fine at lower boost levels.

the flow through the td04 will be better so you wont get as much of a backup of heat. its not ideal, but it will work fine.
