1997 grand zj

I just got my 97 and was wondering I heard a lot of people say since I have the 4.0 if I straight pipe I won't have enough back pressure to run? Need opinions cause I hate how silent my jeep is.

I have a 98 4.0l I cut my cat off and just welded up a 40 series flow master and the tip off the old exhaust and made it a turn down. And it's def loud and can hear it coming. I love the sound of it and everywhere I go people like it also.

I ran an open borla header up until a few days ago. What a sound! Boy I miss it. Anyway got low end torque back when I put an exhaust back on... if you run the jeep in the mud you might want to do something with your cat to keep it from getting boogered up
