Exhaust shop?
 

Can someone here recommend a solution for eliminating lawn mower noise? Maybe a shop with experience in higher end cars? I have no experience with exhaust, and had a shop weld in some cheap free flowing mufflers on my car (after the oem exhaust pipes failed and were cut out)

Car sounds beautiful at idle, and over 4000rpm but the lower end is quite bad even with the mufflers - this is a V12 engine and restoring the original OEM system is not something I want to spend $4k on.

VPD might give you a VI for it.

Youtubes, find something you like, bring your plan to an exhaust shop.

Just unplug 4 plug wires and run on 8 cylinders.

You running on a single cylinder? What’s lawn mower noise? Lol.

Piping is piping really, perhaps a higher quality muffler, or maybe you just need to add a resonator. Does it have a cat? Maybe add one?
