The second part of the Maserati Mistral rehab involved a new exhaust and reconditioned fuel system. Quicksilver in the UK supplied what I would call an “exhaust kit” it was an assortment of pre-bent tubes, mufflers, and hanging tabs. We had to perform all of the welding, add the mounts and flanges, as well as heavily modify the rear muffler.
I always prefer an OE style ANSA or Abarth exhaust system on vintage Italian machinery. Mainly, I find stainless systems produce a “tinny” sound – I have no proof of this – just my ears. However, because of time and budget restraints we opted for a stainless system from Quicksilver Exhaust in the UK for this project. Overhaul I was pleased with the quality. They did mess up the rear muffler, in more ways than one. The factory ANSA system is shown on the bottom.
In the middle of the COVID pandemic, it seemed unreasonable to get a replacement muffler from Quicksilver in a reasonable amount of time. So we cut open the supplied unit, and began performing surgery.
We were able to shorten the 1-2 pipe and flip it 180-degrees. From there, we shortened up the housing TIG-welded everything back together.
That’ll do! The shortened muffler came out pretty well. The extra tailpipe length on the replacement muffler is made up of a set of polished tips that will be welded-on during the final fitment.
