Anybody know of a good alternative/place to buy Redback mufflers? They're an Australian company that makes kits for Holdens with 3800s (yes, our same exact engine) in them. By far the best sound I've ever heard a 3800 make. Problem is they're expensive AF to get shipped back here to the states.

There's a handful of other videos on YouTube with people running similar setups.
