I’ve got a ‘93 454 burb I wanna redo the exhaust on. Thinking a cat delete and a mangaflow with some mid length headers. Will the mid length headers cause clearance issues? Will i need a tune after the cat delete? Should i run true dual? thanks

Do you have SMOG inspections in your area?If you do you can't remove the cat...at least legally anyway :).I removed mine for a while just to see if it made a difference...it didn't except for the nasty exhaust smell so I put it back on.Shortly after that I had the Flowmaster replace by a Magnaflow and that was a big improvement in sound,none in performance.

See my reply in your previous thread..... Single muffler with stock pupe, no cat.
I included pics and video, too.
Cheap but effective to get more sound. Lol.
