Any recommendations for a s/s back box for my MY91 2.2 non-turbo non-cat Legacy . The previous owner had fitted an Ashley backbox which is quite noisy and while ago the middle box rotted out and I replaced it with a length of 2" s/s piping which left it so noisy that I had to blank off one of the tailpipes to avoid getting arrested . This also gave me a noticible increase in power .
The whole system is now rotten and I intend to make up the pipework myself and just need a s/s back box that will fit over 2" OD piping .
