If you're still satisfied with it just keep it.

If you like it and there is nothing wrong, I'd keep it. No sense in spending more money on something you might not even like.

While you're at the muffler shop with your Jeep up on the rack, see if the headpipe (the one right off the exhaust manifold with the O2 sensor in it) and see if it's got a "crush" in it. It may appear to be there to clear the front driveshaft. Have the shop make you a new one and put a sweep into it to clear the shaft. Of course, it will have no "crush". You will feel the difference.

It's from the factory, that's where. Eliminate it by changing the routing of your headpipe and eliminating the "crush" and experience more power and throttle response.

Keep us informed. Some day I may tell you what the "crush" is really there for, and it ain't to clear the driveshaft.

Okay, I'll tell ya. It was put there to slow down the exhaust so the catalytic converter would heat up sooner. It was disguised to look like it was for front driveshaft clearance, which it was because it was routed at a 90* angle instead of two 45* angles..

Go to the muffler shop now.
