FW: [doc] FW: Exhaust article

["Chris Parnham" <cp@xxxx>]

Exhausts,
We all know how awful the original DeLorean "stock" exhaust system is, cast
iron manifolds, pointing "backwards" going around the back of the engine (
warming all sorts of pipes and wires up) and joining up and going through an
( in the UK) unnecessary cat, finally going through a silencer box that has
a LOT of back pressure. It was of course intended to meet strict USA
legislation, but it did restrict, considerably the power of the car.
Martin Gutkowski recently talked to a specialist exhaust firm in Nottingham,
who do custom Stainless Steel , free-flow Exhausts.
In late August this year my "Delores" the RHD test vehicle went up for some
trial work.
Delores ,being a UK car had never been fitted with a cat, so was already
better than most, however , the rest of the standard system was still in
place.
We deicide the finished system should look "stock" from the back, the
silencer was modelled exactly on the original, using the original fixings
and mounting brackets. The internals however are a different matter! The
manifolds are custom made in stainless, mini banana , three-into-one
affairs, facing the silencer. There are then two "bolt in" intermediate
pipes joining to each side of the silencer. These two pipes can either be
plain, or have cats fitted.
The internals of the silencer can be custom made, depending on what exhaust
note you would like. The one I went for on Delores, is "medium noisy", about
105 decibels, you can certainly hear it in the car, buts it does sound very
racy! Mine is an Auto, so I tend to keep it in first gear when driving
around town, the noise really comes in between 3 and 6 k revs! I've turned
into a 50 year old + boy racer!
Mark Bourne has been "re-commissioning my "as new" 111 mile 1983 car. I
decided to have a "extra special" system all polished and very noisy.
Lefty is being converted by our own expert tin basher, Chris Nicholson, into
a full BTTF show car. I wanted something extra noisy making for that!
You will of course remember the bit in the film where the BTTF car backs out
of the van and revs up. Well there is some debate as to whether the sound
was real or dubbed in. Ask Mark Bourne's neighbours, who have to put up
with the sound each time he backs Lefty out of his garage!!!!

Dyno tests show about a 20% increase in power.

( UK READERS) Lefty along with 3 other special DeLorean motor cars will be
at the NEC on 9th and 10th of November, don't miss it!
