what are some of the good cat back systems for the 99 cherokee

i just finished my Aero 2525 last night. sounds awesome. very deep and throaty. not too loud though. I put on the Aero resonator too so it didnt sound real raspy. just deep. my neighbor has a Flowmaster 40, and my last cherokee had a magnaflow. Aero has a better, deeper tone. there is a sound clip on youtube.
search: XJ Aero 2525. check out the clip thats black with the white lettering on it. tell me what you think.

Aero Turbines are nice, but spendy. I would say find a muffler you like and have a custom exhaust setup by a good local shop.

2.5" from the "S" pipe to a Flow Master 40 through a custom bent tailpipe that exits out the right rear corner was $200 installed.

True true. But Jeep owners are professionals at finding things for cheap. 2525 Muffer for $75 thanks to Craigslist. 2525 Resonator for $56 thanks to Craigslist. 2 sawzall blades, a 2 and a half inch muffler adapter, and a case of beer (for my buddy who owns the welder) later, and brand spankin new catback for me!!!.....

try looking at some web sites you can get some good deals depending on what you want i like the magnaflow's they are nice

Not all are successful at finding cheap stuff. I usually am tho. Why did you choose to go muffler and resonator?
I was personally thinking about getting a new cat, running some new pipe and just running a resonator of some kind. Probably magnaflow.
