Ok little update. After much hunting around I finally went with an exhaust. And probably against some people on here, I went with a powerflow Firstly because I knew the garage second because they had done my cars in the past and thirdly it was fully customisable, I didn't want some stupid Jap looking box and I didn't want a straight cut I wanted a slash to match the bumper lines.
I Must say I'm 100% happy, it sounds & looks amazing and I have noticed the car pulls better in higher revs.
Will get some photos up but here's a youtube link for now
