Im sure there will be another group buy we can organise. I'm waiting to see what Hitech Mufflers in AUS come out with as their 350z exhaust was really good - better than any other on market based on gains.
Also waiting to hear more on the R2C performance intakes, as these are looking good. Easier to install/maintain than the G3 and i like how it seals up with the shield when the bonnet is closed
