I'm Awesome
Cats take a lot of definition out of the exhaust. I've hit a cam, and I like to hear it.
I would also assume you've never seen the honeycomb inside of a cat. Exhaust getting through is like trying to pour water through a concrete filter.
A y pipe will have the same effect.

Never "Ass U ME"........lol I have seen plenty of them and installed and removed plenty of them in my lifetime.. getting ready to install a 3" high flow flowmaster one on my rig tomorrow actually along with a new muffler.. If you wanna hear your exhaust that's fine, I like to hear mine to, I think we all do, its a curse....lol.... But in the end do what you personally like. After all its your rig, your time, your money..... And Yes a cat can and does change the sound of most all systems.
From my experiences and research...
A Y-pipe does not have the same effect of a proper h-pipe/cross over pipe or x-pipe. With a y-pipe both banks will hit at the y. If one compression stroke is stronger then the other it will push its way through bottle necking the other adjacent firing cylinder. i.e. incomplete burn and or not running as efficient and strong as it could..
An h-pipe or cross over pipe or even better an x-pipe, in a duel exhaust set up will allow it to fully expel the gasses from both banks in a more efficient even manor. Letting all the gasses out of the cylinder on each stroke/compression faster and more evenly, with out pushing one back or putting one partly on hold if you will, will allow a faster cleaner burn to continue on each firing of the cylinder.
This is of course only comparable and valid comparison with each systems having the same pipe size as each other. Pipe size will play a major role in the way that each style will perform.
Not a challenge but...but this is how i think/work.. If I am wrong show me that I am wrong, and show me the correct way or proven info so that I may learn the correct or right way.. I am always willing to admit when I wrong with no issue. My info comes from working on many types of vehicles for the last 20 or so years. OK now I feel old...thanks.....lol Not professionally mind you...lol
Sorry Airman didn't mean to steel your thread....
