I bought my Astra with standard GM exhaust backbox. Together with prodrive kit it just didn't look right.
I decided to go back to standard look so I got Irmscher backbox and straight through centre section fitted a few weeks ago.
Yesterday I finally had my car washed so I took some photos and recorded a video.
Opinions?
