If you add slip ons and Ac, you must re-tune correct?

what about killed cat and AC with stock mufflers?

Killed my cat last week, yes it sounds a little better, but I need more volume!

 

Follow the link in my previous post to the Supertrapp forum.
They say slip-ons and air filter NO tune needed. But that's still with the cat.
Being the 02 sensors are pr-cat, shouldn't make a difference wether the cat is there or not.
Stealer will tell you you need a tune for ANY change... exhaust or filter.. BS in my opinion.

 

Well done! As others have said this will be useful to many!

That's what I was thinking. I think the cat must have some muffling effect on it. Get rid of it and it's a straight pipe.

 

See first post..
Now with 4" STOUTS...

If I installed Cobra slip on drag pipes and put the stage I a/c and had it dyno'd, the dealer said the cats would be eliminated. This is on a 2012 Heritage Softail Classic. Is the 2012 different as to where the cats are located?

 

From what I understand cats in the muff on the Softails
