I have spent today fighting with a nice exhaust(mainly because my semi-auto beetle has the larger oil pump so it doesn't fit, (well i cant get close enough for the exhaust to bolt up to the motor)

Which got me thinking i may just cut the old exhaust up and build 2 small 3cm extensions.

But the questions im asking is what do the pipes from the carby to the exhaust do??? On the stock exhaust they seemed to be blocked off.

(do i need to grab a pic to illustrate what im talking about?

pod i`ve got to finish this thing one day

What sort of exhaust is it??
all the ones I've looked at had enough clearance for the pumps..

the exhaust can't be too close to the ATF Pump as the ATF can overheat ...

those heat riser pipes are really needed in the winter...
they are also what makes it so hard to bolt on an exhaust system to a beetle...

one end usually is mounted solid to the exhaust connection which can't be moved...
the other end is a bent piece of pipe with a flange on it..
it can drive You crazy....

another trick - You can use silicon on the exhaust gaskets etc to help stop any leaks...
it works great - and especially helps on those heatriser pipes gaskets...

any chance of a photo of the exhaust??

Heatrisers...

the exhaust goes up thru the solid mounted connection
up past the inlet manifold which it heats up to STOP the inlet from freezing up in cold weather...
it then goes down the other side into the pipe and back into the muffler...

some heatrisers go from Left to Right/// Mine..

others go Right to left....

thats a problem with alot of empi exhuasts
cos full flow oil pumps cause the same problem

those GT twin tip systems dont fit semi autos and full flowed engines
