late MA12 engine

i spent a lot of time and effort trying to seal them up, and it wasnt even on my car!

I think there is a lot to be gained from doing it though, its a relitavly free-flowing manufold as it has some length to breth before the restriction of the downpipe, also, with the second cat hacked, its efficatly a straight-through system apart rom the back box.

i was think personally of getting my mate to weld the pipes closed, i have got a new inlet manfold to replace the current one and ill be going to get a cat maifold from the scrappies to hack to pieces so i can keep all the orginal bits should i need to put it back to standard
