Hi all,

Trying to source a used aftermarket catback system or just backbox for my new 2007 3.0si as the stock sound is rubbish! Open to what you've got, as long as it's a bit louder than stock and sounds growlier then I'm happy!

Best wishes,
Dan
 
How about fitting the bypass pipes. A well documented mod on here.

There was a group buy on here a couple of years ago by paza3 from memory.

Might look into this - where's the best place to buy the pipes?
