I just found this out for myself. I had purchased a Dasher manifold and
dual downpipe last fall and when I started to work on it a couple days
ago I found there was no way to get that manifold in there without
modifying the engine mount. I opted against grinding material off the
mount and found a different manifold.

In discussing this exhaust issue with some of my mechanic friends,
everyone of them warned against opening up the exhaust too much. They
told me that I may get 5 to 10 more horsepower, but that would be at
over 5000rpm and my lower end torque would suffer. With this in mind I
am opting to use the manifold from a 1.8L Golf. It's the type that
requires spring clamps to mount the downpipe on. All I have to work with
for the downpipe is the end socket part with a short piece of pipe
attached. The pipe that comes out of this socket is approx 1 3/4 in
diameter. I will be removing this smaller pipe and using a 2" pipe I
purchased from Summit Racing and manufactured by Hooker Headers. It's a
mandrel bent pipe with a 180 deg bend with 6" and 15" legs, very high
quality. I'll be cutting it somewhere around 110 degrees in the bend to
put the pipe past the drivers side engine mount. From there is will turn
to the rear at 90 deg and then it will be in the "stock" position. I
figure the 2" pipes will provide great flow past the manifold and the
Golf manifold will give me some needed back pressure. If I need to open
the manifold up more, I can always grind it out a bit.

Anyone have any opinions on this?
