2ndary resonator delete?

Hey guys and gals,
Planning on doing a resonator delete tomorrow, how would this sound? Would it be toooo loud? Would it sound like a race exhaust? Will I hear the exhaust more on the higher end?(past 4k rpm) please send me your inputs thank youu. Btw I already have a muffler delete, how much louder will it be?

It really is. You can read up all you want about how to please a woman, you can look at all the diagrams in the world, but just like the clitoris, you won't know what the hell an apex is before you actually find it.

From what I've heard res delete gets the most sound other than a muffler delete. People have given mixed opinions on how much a 2nd cat actually increases sound so I'd guess not by much.

Are you talking about the 2ndary cats or the resonator? 2 different things. Cause just a res delete with stock muffler i heard makes little to no difference. Im curious to know what 2nd cats and res delete with stock muffler sounds like.

Gavin@MMW does his famous CSv2 exhaust... i don't know if that has the resonators or cats though... but it's modified stock muffler.

Hmm i could've sworn I saw a youtube vid with just a res delete and i couldn't tell a difference. Then again I have a muffler delete and replaced the stock res with a vibrant res which is prob a lot louder.

Whatever the footlong Y connection goes, I don't believe that is the 2ndary cat, btw how will it sound if I delete the 2ndary cats?
