will it make my exhaust louder? and mayb it i dump it after the flowmaster than if it was sticking out the rear?

and i got 2cats on my 99 f150 5.4 if i cut the one with out the o2 sensor will that do some work too on making it louder?

otherwise idk what to do yall

 

If you want that Flowmaster louder, then cut the pipes off directly behind the muffler. No turn downs and no pipes behind. Just leave the exit of the muffler open. This will give you the most volume and tone out of that Flomaster.

If you have 2 cats, then you will have to replace them with maggie 94106 cats for even more volume.

 

thank you mr. man lol
