Looking one good silence muffler.

[V6quattro]

Can anyone advice my a good silence muffler with a 60 or 55mm input? I really like to get my car silence on cruise. So i'm planing on installing a butterfly valve in my 3.5inch exhaust and rout the exhaust to a silence muffler. Im controlling the valve with the VEMS ecu trigger by RPM and boost.

I'm trying to find one fit on my A6, needs to be quiet but not impede the flow. I'm currently searching through Flowmasters web site looking for a chambered silencer, rather than a straight through baffle type.

Thanks Andy. They have some nice mufflers.

I think i will try the stock rear muffler first. Anyone have any experience how loud it will by only use the rear muffler on a S2?
