I just received my first 911 Tubo and I am a happy Daddy !
The exhaust that came on it is a custom exhaust. 3" with no CAT.
It sounds like a race car ! It is awesome.
The problem is , this is a daily commutor for me and the wife has sensative ears(girls?).
I don't want to give up the great sound but would like it to be quieter for cruising on the highyway.
A month or two ago I was surfing the web and had noticed an adjustable exhuast, but I can't remember where. It had an actuator that in low RPM's sent gas through a muffler but opened up to the full straight pipie when pushed.

Does anyone know who makes a peice like that ?

 

DMH Cutouts is all i can think of.

You would need a muffler first and then add these to them.

ATP turbo sells pneumatic ones:

Then there's the complete exhaust. Made by M&M in Germany, full stainless, eletronic control, pneumatic valves.

Select "Valves version" from the left. If the products in their pages seem familiar, it's because FVD Brombacher sells them...

 

Thanks for the help.
I want to keep my exhaust and add an actuator to run through a muffler at low RPM's.
Any thoughts?

 

Anyone heard of Xforce Varex

 

switzer can make a quiet exhaust that opens up to be loud ive chatted with them about it your looking at about 4000$ roughly though

 

9ff and Kreissig make these, but they are expensive.

 

I noticed the RFF, which looks like what I need, but way too expensive for my blood
