Repair of the exhaust system

An old, rusty and worn Lamborghini Espada rear muffler from Ansa Marmitte cut open


The next project on the list was an repair of the original exhaust system which was a bit leaky and did not really contribute to much sound dampening. Actually, the car sounded like an old-school V12 F1 racer which was kinda cool, but in the long run the sound became too violent and a system without any back-pressure does not give optimal engine performance. Since I do not yet have my own garage and the necessary tools, it became my skilled workshop that helped me out with this.

The metal in the transition from the center silencer to the tube was paper thin and pierced and beyond repaired.
New beefy flanges with four bolt holes for better tightening and sealing. To the left is the original with 2 holes and about half the thickness.
First assembled and spot welded to ensure perfect fit before full welding.
And now fully welded on the exhaust manifolds, with a nice thick weld seams.
Similar flanges were welded to the tubes.
The complete tube set with center silencers.
A little paint to complete the work.
The original and wonderfully ANSA Marmitte exhaust tips were in good condition and were cut and reused on the new muffler.

The two rear mufflers are handmade by Evald who is a skilled mechanic and steel construction specialist who has worked for some of the leading rally teams here in DK. They are made with some kind of internal “guides” which should provide a vortex flow for better performance.

I couldn’t wait to hear how it sounded on the road and I was a little worried if the sound was getting too dull now that I’ve heard Espadas that sound a little too discreet in my opinion.

But I was not disappointed, it sounded completely as I had hoped. At low speed and at idle it sounds civilized but you have no doubt it’s a powerful V12, but when it gets a little speed and passes 3500-4000 rpm it acknowledges with the genuine seductive Lamborghini growl. Whats not to like?
