I've got a brand new Ford Falcon FG XR6 Turbo (purchased a little over two months ago), and I'm interested in having the exhaust system upgraded. I'm still waiting on the specifications from the company who I'd have do the upgrade (owned by a mate). He's suggested that what he'd start with would be to install a system with a nicer note and improved performance by about 10%. It was a quick conversation, so I couldn't get anymore specific details than that just yet. All in all, he said it would typically cost around the $700.00 mark, with a view to doing more once the car has passed the 20,000km mark (it's only just done 2,400km). Anyway, my question is...given how new my car still is, is there any real reason why I shouldn't be looking at an upgrade so early on? Also, is there anything I should be asking, or be aware of when upgrading? All I want to achieve is to get a nicer note - something a bit more noticeable. If it comes with a bit more grunt as well, that'd be good. Any advice would be appreciated!
