    Intake and exhaust manifold trimming 2008 rxt-x

    I am in the middle of stuffing a rxtx motor into my stx hull and have run into a few snags with the narrow top deck on my stx.

    The exhaust manifold is fouling on the hull where the freeze plug bosses near the middle and front cylinder. I live in Houston so I am not particularly worried about freezing, can I machine those mounts/ports off and weld them flush to the rest of the manifold?

    What is the exhaust manifold made of? It looked like cast aluminum but I want to make sure before I start chopping.

    Finally, can I machine a little off the flange face from head to manifold to tuck the manifold closer to the motor?



    The intake manifold originally hit on the front ecu mount, with that removed, it now hits the bottom corner of the front and is close to hitting the mounting bosses for the accessories. I thought I had a picture but it doesn't look like it.

    Can I trim the mounts off the plastic manifold or is it hollow under the inserts?

    Is there a cheap, l smaller manifold that tucks closer to the motor?

    I can cut the hull but I was hoping to minimize the glasswork.

    Thanks,

    Sean
