    Well after 16 years the muffler is starting to rust through on the 03, not loud and annoying,.....yet, but

    Nothing loud, no cheap Flow masters or any of that junk just a good quiet/ semi-quiet cat back system

    Anyone found some great deals here lately ?

    Thanks

    MBRP I scored mine used, but they are reasonable new too. Very good sound. But not loud or annoying

    I got a Walker brand when I had to replace everything from the headers back. Sounds a bit louder than stock and was a good price from Rockauto.

    I have the MBRP as well. Great sound. It's not exactly quiet on my 06 3.7L. You can hear it from inside the house. A bit of a drone at certain speeds too. Maybe I made a mistake on the install?

    Great price, sounds ok, but only available on Flea Bay , sad. Stopped using it after I lost over 500 bucks from a number one seller who suddenly disappeared . Paypal nor FleaBay was any help at all

    How does this sound compared to OE? With a smaller diameter, round muffler, I'd expect it to be not only louder, but to have some drone as well.

    Honestly it’s quieter then I expected. In my opinion it what a factory “performance” exhaust would sound like
    I don’t have drone. Ordered another for the 03 , I swear it’s louder and they returned it within a week no charge. And it’s it’s quiet like The 02 now

    Thanks... I like quiet exhausts, but don't mind a little noise if I open the throttle. Nice mandrel bends in that product, from the looks of it. When my Walker rusts out, could be a few years yet, I may need a new tailpipe and when you add it all up, this seems like a good option, if it lasts and isn't too obnoxious.

    Yea. I have other cars that are cam’d and loud. I don’t mind the jeep being quiet but the stock muffler was just too quiet. This I feel is like a good balance for fhe price.

    For sure... in a daily driver like my KJ, I like it very quiet so that I can hear other issues, like suspension or drivetrain noises. If I still had my leaking, loud OE muffler, I never would have heard the peculiar squeak that the KJ made before my power steering pump blew into two pieces. lol.

    The Walker 18944 SoundFX so far is quite nice. Quiet inside, a bit of a throat to it standing next to it. I painted the entire thing and every seem and weld in gloss black BBQ paint- except the drain hole, of course- so we'll see if it doesn't rust out in 3 years.

    I'm looking at this one right now ! It's the 2.5" ?
    I'm looking at the "Performance" kit. If this is what you bought, did the part in front of the muffler doing conversion 2.25->2.5 ?

    Yes, everything fit up perfect, 2.5"-2.5"! Nice throaty sound normal driving, and great growl when I punch it!
