72 Dart Swinger 3.6L Pentastar +T5

Have you seen this thread? Might help your Honda fart can issue.
No more drone!
I haven’t been keeping up with the whole thread, but are you running fully dual exhaust? I would tend to try a Y pipe to combine into 1 and then another to split back to dual IF the look of true duals was a necessity. I have yet to hear any 6 sound good with duals, and I like 6’s particularly inlines.
