New exhaust primaries and collector

I could no longer ignore the fact that my exhaust flanged was warped and leaked, and I also found something that looked like a small crack on the 4-1 collector.

The exhaust system on the EU4-version of the car is welded and can't be removed without lifting the engine out - something I've had enough of for a while - and as one of the primaries has cracked before I felt like I just wanted to buy a new manifold that was more easy to remove instead of repairing the old one more time.

The EU4 collector also looked like it was limiting exhaust flow, but that was just an hunch.

So I removed the old system with an angle grinder and steel saw, and bought new CSR260 primaries and cat/collector from Caterham. The new system holds together with springs and can be mounted with the engine still in place.

Old vs new cat/collector

The new cat/collector moved the silencer a bit outward, so I have to make new silencer mounting brackets. I'm also thinking about buying a new silencer but that can wait for a while.
