I know the manifolds are completely different, but we will be putting an 18rc exhaust onto a 2TG, will the bolts match up from the manifold back?
i.e where the 4 pipes come together
I don't know for sure, but I'd be surprised if it was a direct fit. You'll probably have to take it to an exhaust shop and get a new flange welded on your pipe and/or have the pipe shortened/lengthened/bent to meet the manifold dump.
