stock looking performance exhaust.

[redhot]

The Vintage speed is similar to that of Klaus tuning, CSP and many others. Looking at some pictures it seems that they hang pretty low, reducing the clearance to the ground.
But a merged system that still exits out the rear cut-outs is not that available. I would love a design like the CSP supercompetition for a type4 engine. This also removes the large mufflers to the wheel arches, meaning not problems with clearance.

Perhaps someone would chime in with some exhaust theory: does it really matter that much on an close to stock 914 2.0 engine?

The best ehaust for a street/semi-competition motor is a 4-2-1 with 30"+ primaries and similar secondaries depending on the state of tune. However, the architecture of the flat 4 boxer engine doesn't lend itself to this sort of design so you get the compromise 4-1 layout with a merged collector at best. At least CSP and the like have got the 4-2-1 concept firmly in their blood to attempt it on the VW flat 4 engine but the spaghetti pipework has to be an expensive work of art. A 4-2-1 arrangement should give a more flexible engine that may be down 1 or 2 bhp on the 4-1 unit but that flexibility shows itself in A-B times and economy.
