An fyi – for all the coupe owners 4200 & Gransport.
I’ve been having some minor loss of power on my Gransport, also a slight eggy smell. So all the evidence of failing cats.
There are many options available including the very expensive Larini replacements.
I opted to get custom 200 cell cats made up as a direct replacement.
If anyone is thinking of getting theirs replaced let me know & I will provide more information on The Exhaust Centre in Thatcham. They have done many Maseratis so experienced.
My cats were also cracked and in very poor condition so a very good option and I’ve retained my xpipe.
