Title: Exhaust Manifold
Post by: Alex Pope on March 7, 2017, 21:43
I'm looking for a reasonable exhaust manifold and have read a number of posts recommending the CHE manifold.  I've searched and it seems like the place to get it from is  delubozparts on ebay - is this correct?

Secondly - what is the difference between the CHE manifold and the likes of these:

Finally - is there any advantage going for this type rather than sticking with the standard, especially since my pre-cats are already gutted?  I'm changing the down pipe so thinking it's a good opportunity to do the manifold, and having a manifold ready in caase the three downpipe to manifold studs are seized may be a good idea.

Thanks

Zero exhausts are very pretty and good. High price tag though.

The biggest blocker in any exhaust is the cat and back box.
The manifold is a great place to start
But to get the benefits, you'd need to look at some kind of fuel control via piggyback or standalone ecu.

Thanks.  No intention of changing ECU so I'll aim to stick with existing manifold.
