Hello everyone. I'm looking at getting a better mid-pipe for my N/A car. Which would be better for me, 2.5" or 3.0" tubing? I believe the Magnaflow is 3.0", the Bassani and Kooks are both 2.5". I would assume that a larger diameter tube would be better if I had a S/C or am I wrong? Also, with the addition of high-flow cats, will I need to get a custom tune?
Regards,
Jon
