Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 Pinging: Removing exhaust cats, modding baffles?

I have been trying to find a way to reduce or eliminate engine detonation at higher revs, AKA pinging (pinking).

Here in the US max fuel octane is typically 93 in my area. Everything I have read on the forum points to a less restrictive exhaust as being effective in helping to eliminating pinging.

I prefer a more quiet exhaust due to having tinnitus in my ears so installing straight pipes is not my idea of fun, and going too unrestrictive can cause potential issues with throwing codes on stock ecm I have heard from S&S.

So what is the advice of people with first hand experience with modifying the stock exhaust system.

There is no emissions testing here for motorcycles so I could remove the cats. What are the pros and cons?

I have also read about folks modifying the exhaust baffles. Again what are the pros and cons?

My experience over the years with cars (not motorcycles) at least from my own experience, and talking to owners of aftermarket exhausts and home made mods has been pretty consistant in my view. Many folks are happy for a bit with the new loud sound but soon grow tired of it. I feel that the majority of mods to stock exhausts, or aftermarket systems create drone and/or are too loud, or some other kind of unwanted result that the majority of folks go back to stock, or a quieter solution IMHO.

Owners with first hand experience: What mods can I do that will not make the pipes too loud, but have a big effect on pinging?

Thanks
