I have a 85 280ce with a 5 speed that was given to me and I'm restoring it. I'm going to build a aftermarket exhaust and I'm looking for something with a sporty note but nothing over the top. I was going to go with a Borland muffler at the end and 2 glass packs in the middle as a resonator. Has anyone built anything for there m110? Any suggestions would be appreciated, also I'm using the stock pipes.
