Guys,
The systems are back in stock. We received 4 new systems Today and as of now we have 2 available at a special rennlist discount !
This time of the year is extremely busy for our manufacture in Germany and are not able to keep them in stock for long, as the demand is higher than the supply.

Also proven to make power. Tests performed same day and chart shows best run from OEM set up and best run with M&M set up on a bone stock GT3 RS 4.0

fyi,
my bone stock 503Hp Fiat 430 Scuderia ran 428whp on a dynojet.
So, this M&M setup makes the Aero Beetle 3.8RS more powerful than a stock Scuderia, sad but true.

Same dyno .... as you already know. You just forgot to say that after I tuned the car and installed the full exhaust it made 490 WHP +++

+1 been very happy with mine. Noticeable power increase over bypass pipe, low end
Sounds just right. Not as loud gmg bypass with side mufflers. Only neg a little heavy but still saving 30-32 lbs overall

Correct, they are heavier than OEM, so they can last, differently from OEM or CUP, cracking left and right.
The weight savings taking in consideration all the brackets is in the 40lbs range. For those who want even more weight savings we also offer this same system in titanium.
Glad you are enjoying it.

system going on as we speak. Can't wait to hear how it sounds and the power bump. Coming from fabspeed exahaust + sharky track pipes... it'll be interesting to see the results!
Thanks Eddie

On a 3.6 car about 10-12 WHP and little torque.
On a 3.6 car you will have minimal drone in low RPMs using the 3.6 specific sizes. It's really minimal and only in low RPMs.
On a 3.8 or 4.0 there is no drone. Perfectly capable of a conversation on Bluetooth

A bit more than the factory set up and A LOT less than the side deletes with OEM muffler. The M&M center muffler is very different than the factory and also heavier, but doesn't crack, break and if it does, it has warranty ![Wink](https://rennlist.com/forums/images/smilies/wink.gif)
Also the OEM with side deletes give you 0 power gains. It's a easy and cost effective solution for those looking to drop weight and in case of Cup cars, just replacing the extra expensive link pipes.
