Hi Guys,

I am looking for a QP M139 Sport GT S Exhaust (Muffler with Valve) - looking to upgrade mine on my 4,7S 2011 QP.

Thanks

There are other used Maserati mufflers on ebay that have valves, but you really have to look closely at the shape of the muffler housing, as well as the location of the inlets and outlets....none of them seem to have the same configuration as the QP mufflers. I'm always searching too....4 months of looking so far...and no luck.

There is a guy breaking a left hand drive GTS. He wants 1k each side! May as well buy Larini. Or contact Jason at Jaren metalworks. He has just done mine and they are excellent. Pm me and I can send you a video of mine.

Unfortunately it is impossible to get a real world comparison of the various valved muffler options, so I have to rely on videos and opinions. I have driven 2 QP GTS's and love the sound and tone of the factory valved mufflers. Some aftermarket mufflers sound more like a "musclecar" or have a "tinny" sound....which I feel is not in character with a fine Italian machine. Surprisingly some videos of cars with the mufflers removed sound pretty good, mellow at low throttle, and really howl during acceleration. I may just do that....

Here is mine in French sunshine with modded boxes and x pipe.
