Does anyone have any experience with the Billy Boat exhaust for the B6 S4?
I heard a sound clip and I liked it.
Just wondering about fit, etc.
Seems to be much more economical than the Milltek.
If I read it correctly it is around $1300 from the downpipes back.

Some of their other exhaust systems for the Corvette I have heard in person and sound very nice with a nice boost in power chipped.
Thanks
