I'm happy to travel to Sydney if there aren't any though

Otherwise are there any reasonably-priced systems commercially available for the B4? From what I can gather there's the MRT at close to $3k, and some other companies that sell just the dumps for $1k+.
Another question, is the note of the exhaust mostly determined by the muffler? I.e., if I pick the same muffler as someone in the exhaust sound thread with a GEN4 am I likely to get a similar sound?
(New to car modification here, I'm sure you can tell haha
