Been searching for a few months and not much has come up apart from 4-1 manifolds but want a 4-2-1 so the only 2 i can see available are these.

Toyosport

John Ashley.

Which of the 2 would be the best & ground clearance must be good.

Would like one before the engine goes in because i will be getting a system made up from the manifold.

Avoid the Toyosports one, they are crap for ground clearance.

I used John Ashley, had it welded for more clearance underneath, easy enough for exhaust place. Should of bought it when you u2u'd me. I think you've been asking about exhausts for months now though

wish i had a proper manifold made, instead i ended up buying a john ashley then having it chopped for better clearance, would have made more sense to have had a custom made manifold all along

Bloody hell no another manifold question.

As said before though, it will be wasted money on a pretty much standard engine.

Unless you are going down the TB route, the standard manifold will be more than enough.

Yeah std one will manage at 180 odd which you would struggle to genuinely make on standard ecu set up etc anyway.

Standard manifold has plenty of ground clearance as well, mine tucked up nicely round the sump.

I have a 4-1 manifold from an astra gte - its obviously aftermarket as its over sized, but it tucks up close to the sump, has the proper flange just after the sump and has plenty of ground clearance - unfortunatly, there is no make on it,
