I've had both and I can't really tell what's louder and back fires more... I want to say the H pipe was a little louder but the x pipe back fires a little more? But its kind of hard to tell. I am debating between keeping my aftercat x pipe or going back to the stock h pipe when I get a new set of axle backs (Either Roush or S Types)... what is everyone else's opinion? Which one is louder?
I have a lethal performance off road x pipe but i didnt use the cat deletes so it basically a after cat x pipe and it reduced my sound ! But i had some DMH low profile cutouts welded on to it ! So it sounds crazy loud with a push of a button
Don't really care about the 3-5 horsepower to tell you the truth, I'm a sound guy especially since I don't track the car (plan to at least once or twice but never have) so I think I am going to switch back to my stock mid pipe once I get the S types
