I'm considering getting a new full exhaust system for my '68 Imperial. From what I seen, it sounds like the TTI 2.5" system with the Dynamax mufflers and Turndown tips are my best bet. Part #: https://www.ttiexhaust.com/Classics-Ex/C25MWM6573.pdf I'm wondering what others have experienced using this set up. Is there a better option out there? I'm running a stock engine, although it does originally have the 440-dual exhaust option.
