Yep saw that long time ago, similar but not the same. Mars also make a similar setup but horrible quality imo. MXP seems noisier than the STI & where to get from OZ? There were a few others I really liked from GReddy & Fujitsubo but getting them here from Japan made them expensive.
Personally unless you're chasing biggest hp gains NA I wouldn't bother with a front pipe or even an overpipe - just leave them stock.
Thanks to @
jpbrz I already have a stock midpipe to test & modify, I will find out Sat am what can
really be done with the limited space in the middle of the car. The aim will be to keep stock pipe diameter but have 2 resonators instead of 1. The perfed gasket will come out to rectify hi-flow to system.
