exhaust question

Right now im running test pipes+remus race mufflers. I want to gut out the secondary cats, would a resonator delete be louder than a secondary cat delete on my setup.

It's my understanding the resonators only reduce rasp. Cats reduce flow so getting rid of the cats will be louder. I don't believe the resonators reduce sound volume but I might be wrong

Same as above, my understanding is cat removal is louder and resonators get rid of rasp. The differences here though I would think are marginal. What are you looking for?

I would prefer not to have a sound increase haha, but if it is only slightly then it is fine.

cat removal, remus also sells cat deletes, as I have their cat delete and straight pipe as well, the car is going to be really fucking loud, like really fucking loud if you dont mind it, do it.
