So maybe the exhaust forum might be best to ask this in but I thought that you guys would have personal experience on A6s and their sound more than the other model guys. I was just thinking of upgrading exhaust for my 99 2.8Q I want it to sound mean and not sure which one to buy. Also is it worth it to just get a new muffler or would the best bet be getting a whole new system (any performance increase isn't too important ) Thanks.!
