Creating a Sport Muffler.
I picked up a Leistritz exhaust a couple of years ago on ebay as it was cheap and thought it would make an excellent candidate to convert into a sport muffler. I'd seen instructions over on Pelican on how to do this and just a few months ago the thread I had bookmarked was updated with a slightly revised design. So with those instructions I set about making the modifications.

Here's what I started with.
When James' (23e Heure) GT conversion was finished the exhaust fitted to the car originally had an awful, ear piercing drone so I swapped it with this one temporarily and it was much quieter for the run down to Le Mans Classic. So that confirmed my £70 ebay purchase was a bargain
I won't go through every step as speedracer54 on Pelican did a great job explaining the process. However here's a few photos of the modifications of mine.
Cutting into the case.
Mask on!
After a bit of cleaning.
Marking out the parts to be cut out.
New hole
Part of one of the pieces cut out put into the hole so it matches the original at the other end.
Once this part of the pipe was cut I need to add the holes similar to the other section. Just look at how I managed to get them all perfectly in line and the same size
A couple of sections had to be sealed off to redirect the flow so with a cardboard template in place I could make the plates to weld in.
With the internal modifications complete here's how it now flows.
Finally I could add the distinctive twin outlet pipes.
After stitching it all back together and giving it a coat of silver/grey VHT paint here it is ready to fit to the car.
Can't wait to hear what it sounds like now. I've seen a couple of YouTube clips and a couple of first hand accounts say it shouldn't be too obnoxious but I'll have to wait and see. If it's too loud I'll treat myself to a new one and chalk this up as another learning experience.
