I would think the same thing. Muffler with no resonator can get louder unless you throw a straight pipe on there. LOL I think Bambam had the cat removed.

I thought the original GT-R that is sold has no resonator unless you ask for one to be installed.

Im Sure youd get that even with the 3rd cat. I have the magnaflow system wish has a resonator and thats how it sounds quite with a nice low rumble when driving around concervatively. But when you get on it. Its Like Pure amazing-ness. I can only imagine how loud it is without the res. Youd deff be turning some heads.
