Countach QV #GLA12997

Since the Air Pump was blocked on my car (like many others too) I decided to have a stainless steel custom exhaust built.
Goal was to have a muffler which looks 100% original, same dimension, same numbers etc. to be able to pass registration test with this exhaust.
In the exhaust are 2 100 cells race catalysts which are bringing the emissions down, the engine runs at 3,5% CO and has 900 ppm HC, after the catalysts have become hot, the car produces 0,66%CO with 80 ppm HC.
Meanwhile I removed the whole Air Pump stuff since it is no more needed.
I still have a set of redone headers, sanded and chromed, awaiting installation...

If any swiss or german owner is interested in this muffler contact me:

Problem of stainless steel, it changes colour due heat

Left you can see a joint of a BMW 3/5-Series, next the original Lamborghini joints
Right are the 3 broken original joints, they use the same since 1971!
The Joints are also from Mercedes (Walker, Fonos, Tenneco 21-80023)
The bicycle cable was to fix the luggage Hood mechanism, you need 3,5m

Unmounted muffler and sanded to paint black

Fixing of the broken joints, I removed the muffler

The Lambda sonds can be seen, they are to survey the mixture only

I painted the muffler heat resistent black, to look like original

Better joints, no more Lamborghini! You can see the lambda sond entry screw

This is the original muffler

This is the new stainless steel exhaust
