Just be careful of your EGTs. The tune will drive your EGTs up and the standard exhaust helps that to happenn, reducing your back pressure and improving your exhaust flow will help keeps EGTS cooler and provide longer engine life as a result. Ive done a decat and removed the rear muffler. Others like Pat have removed the cat and the centre muffler, either way improve your flow. Just some friendly advice mate, its your car though
