Tired Of Your Motorsound Mufflers?

I modified a set of stock mufflers ala LPMM, but with a 1 1/4" crossover. I think it's a great compromise, nice and throaty, not too loud, etc. I think everyone's idea of the "right sound", is different. I might like the 2" too, but decided to start at the lower end. You can always cut them out and go larger. I get just an occasional pop with these, but they sound great when you put your foot in it.

With no interest to changing from stock mufflers, I just saw in PET that motorsound mufflers exist in the US and not in the EU,
while RS mufflers are sold in the EU but not in the US.
same price both but different #
does anyone know if difference there is in sound, conception? just curious

The motor sound muffler was an afterthought from Porsche after hearing many complaints from US customers that the car was too quiet.
Interesting fact: If you ordered your 993 from the dealer with the motor sound option you get motor sound muffler, motor sound tips, motor sound air box, but if the car was not ordered from the factory with the motor sound option and then added by the US dealers you only get motor sound tips, and motor sound air box.
When I made the RSR muffler I went with a completely different approach by changing chamber volume size, instead of messing with the by pass tubes. Interestingly enough when opened a 997S muffler recently I noticed that Porsche went with the almost identical design as my RSR 993 muffler.

Believe me, if the mufflers had exhibited even the slightest amount of resonance, I would have bolted my stock ones back on. At highway speeds, there is no difference in noise inside the car.

All is relative in life, we are talking 130 kph highway speeds.
I really enjoy driving on the autobahn, this is where I enjoy the 993 the most,
but after one hour at 5000 rpm and with stock mufflers, the sound is so loud, I assure you you play drops of jupiter so loud, the singer is screaming, not singing.
If not I would have gone RSR or LPMM, etc and CAT refill long ago

My LPMM mufflers (by Fister) have no resonance issues whatsoever. The popping and gurgling sounds are music to my ears.
