I've got a 1988 Jeep Cherokee with the 4.0. I busted the stock exhaust on it wheeling a couple weeks back and I removed everything from the header-back. I bought a new exhaust system for it but I really like the way it sounds running just out of the pipe that comes from the header. It's not too loud at idle because I have it turned down to idle around 600. But...my question is...Will it hurt anything running it out of the pipe that comes from the header? It doesn't have a cat or muffler. It's just running out of the pipe that comes from the header. I know it's probably been asked plenty of times but I was just wanting to ask y'all's opinion. Some sites say it will hurt a vehicle others say it won't........Thanks for the help!
