Guys, I am a new member on this forum, just wanted to say there is a whole lot of great information here. I have a BA MKII XR6 Turbo, performance wise it is still a stocker. I rang a place today to get a price for a full turbo back stainless xforce system. See link below. xForce Exhaust System As you can see the price on the site is $1550.00. I got quoted just under $2800.00 installed for it, which I though was a bit high. The guy said that the best mufflers price is impossible and that is must not be stainless, I checked with best mufflers and it is in fact all stainless. Does anyone have this same setup? what do you think of if? where would you recommend I go to get it fitted and tuned? I am in Melbourne.
