Just bought my first 86 ( Harley), and am looking to redo the muffler/exhaust. Im trying to stick with that old school classic rumble.
Any suggestions?

no emissions here, so everything is fair game. i'd start with headers first. then work your way back.

Usually just squirt em with a spray bottle of water. Cats hate that. Couple squirts and they'll get the hint.

👐👏🙌 I admire your humor, I tried that and she ran with her tail between her legs. Any other fatherly advice youd like to give?

Unless the cat is faulty, I'd probably leave it alone. You haven't told us which engine your car has, but generally aside from the early cars and the V6, the cat isn't all that terrible. You won't gain as much in sound quality by gutting or deleting the cat as you would from a good muffler. If you want a little power boost in addition to sound, a good cat-back exhaust is the way to go. If you don't mind the install head aches, headers, a good Y-pipe, 3" cat, and 3" catback is a tried and true modification.

Neighbor has a Dodge pickup, V8. Took the muffler completely off, uses the cat as a muffler. Really sounds good, straight pipes clear out the back.

That's almost what I did to my 5,7 V8 TPI.
Unbolted the exhaust after the catalyst, knocked half of the inside out ( even used a vacuum cleaner to get the small parts out...).
Removed the mufler, replaced it by straight pipe.
Great sound, no drivability issues.

Remove every single piece of the exhaust. If you don't want to do headers and y-pipe yet do the rest up in 3in exhaust for time being. Chunk the converter.
