Swiss made is infamous around these parts
3rd muffler bypass at idle?
How does a 997.1 GT3 with a 3rd muffler bypass sound at idle or low rpm? Is it a big difference compared to the stock exhaust? Anyone have a sound file or a vid?

Thx

I have the SW bypass and it isn't much louder if at all any then OEM at idle. Bring it up to about 3.5-4 and it'll wake you up though.
