exhaust question

As of right now the only exhaust mod I have on my car is Pypes Axle-Back muffler deletes with 4" tips. My question is how would y'all think the exhaust note would be if I installed high flow cats in place of stocks and made it a straight pipe, with the factory h-pipe still in place, from the high flows on back? Also will my performance stay the same, go up, or go down? Any answer is welcome and keep in mind I do not know a lot.

You won't see too much of a performance increase, maybe alittle but it will definitely sound awesome. I have the pype bombs too and are starting to be to quiet for my liking. I'm eventually going to get long tubes and high flow cats

I do too but its still illegal and cops will pull you over if he thinks its too loud. I recommend at the very least having high flow cats. They muffle the sound some and you can say ur doing ur part keeping the planet alive.

How do you like the Pypes Muffler deletes? On American Muscle the sample video sounds amazing. I was looking into picking those up.

I love them they sound amazing nice old school bubbly sound at idle
Also I have high flow cats installed and the car is just ridiculous now compared to just the puppies deletes themselves
