My first ecomod. I cut the bell off an air horn:



...and formed two tabs:



...and pop-riveted it into the end of the snorkel.



The comparable part for the exhaust needs to be 20% larger.

This may be a stupid question but what benefits do you get with that thing on the snorkel?

AutoSpeed - Ballistic Bellmouths

In the 1970s or so Mechanix Illustrated showed a tailpipe tip that was a bellmouth with a 'mute', a spindle shape in the mouth, and claimed it was most efficient. I still have the second horn for the tailpipe, but it's a little small and it deserves more than two pop-rivets.

you should replace the exhaust too to a better-flowing one, it helps a N/A diesel

Have you ever considered adding some engine-braking device, such as an exhaust-brake?

No, but I suspect the vacuum pump for the brake booster may need repair. I took it by a mechanic friend today to show him and he pointed out things under the hood; like the vacuum pump and the fuel filter.

I always thought Jake brakes worked by lifting the whole camshaft; but these seem to be the opposite of an exhaust cut-out:

Jacobs Vehicle Systems | Exhaust Brakes

I think I would prefer the KERS solution.

When an uncle of mine had a Suzuki Vitara fitted with the VW 1.6L Diesel, he got rid of the vacuum booster, and it was still OK.

i suspect the vac booster didn't work in the first place or the Vitara has good brakes even as unassisted?

My uncle was not really willing to get a vacuum provision for the booster, and he resorted to the master-cylinder of some local small car that didn't have it. I just don't remember if the master-cylinder came out of a local variant of the Opel Kadett C or out of a square-body Volkswagen Gol.
