Very nice! After modifying my slant headers I can appreciate your efforts and the time it took. What did you do to get the tube square to go into your head flanges?
I have always enjoyed the sound of a six cylinder motor, at any RPM. Not a school bus sound but it has a note all it's own. But I guess every one has an opinion. I just installed a 14 inch magnaflow with a single 2.5 inch pipe. I like it at all rpm.
