RE: VRC BigBore Pipe Users
I got a side pro and the manifold is bent too much for the clutch bolt so i used a regular 16mm long M5 wrench head bolt in the clutch side hole...8mm wrench to tighten it and access is easy then...one thing with these manifolds is they never come loose once tightened down.
I got a rear and side pro and one came with a spring and one didn't.... Sean at OBR sent me a spring express same day i emailed him saying it was missing. both used the same springs
