Ok today I have found out my manifold has cracked.
Im in the progress of trying to sort out getting some money back but thats another story.
So Im thinkg about getting a 4-1 manifold, had a quick look but it looks like GMC is the only place that stocks them.
Is there anywhere that I can order online?

I get embarassed when talking to people on the phone - Sad I know but I cant help it
Cheers guys
