Default Exhaust Question!

Hey guys. I wanted to get some recommendations of what type of exhaust I should run on my 01' Cherokee. It has a straight six with stock exhaust right now, and I want this thing to be heard. I wanted to replace the cat with a high-flow cat, and I want a solid sounding muffler. I'm open to all suggestions!

Thanks

You have to be careful to not go TOO big with your exhaust pipe, otherwise you'll be changing backpressure and losing low-end torque.
