Twin 2.5" or single 3.5" is generally the way to go.

A good exhaust can cost towards $4000+ a cheap exhaust can be had a lot cheaper

Remove the exhaust and just run it off the turbo pipe

I think if you're just after 300rwkws, just bring it to a reputable tuner, verify that you have the stronger bottom end (most 06/06+ bf's came with them) and you should just need a hiflow cat and tune. Would get 300 no probs I'd say.

As for Gold Coast tuner, try HiTorque. A few here use them with great results.

yeah mate.. go and see kent & chris & the boy's at Hi Torque Performance mate.. they can work somthing out for u mate.. I highly recommend them..

first you get the money, then you get the power!

haha cheers guys, I will go have a talk to them and see what they say . Sounds like the high flow might be the go for now , I really do want to join the 300rwkw club though!

Hey guys so I pulled into a exhuast place today to check it out, turns out my exhaust is stock apart from the rear muffler being removed and replaced with straight pipes. This is probably the reason I dont have 300rwkw, question is how much should an exhuast cost? The guy quoted me 2.6k installed including dump pipe, high flow and exhaust. To me this seems expensive but what did you guys pay? and is there a cheaper way

hey mate I got 300 rwkw on a std exaust both mufflers still there just changed to a hiflow cat 3" oulets and 3 1/2 body I think it was. just got a muffler shop to weld it in
