Pretty much all non OEM mufflers drone. It's all of how much you can stand. If its a daily driver on the highway, you better have a high tolerance for drone.

Unless you stock is shot, do nothing. Wife will be happy.

Sorry to bump and old thread...
I recent put on a Flowmaster 50 sub series and for me it seems too loud when crusing around with rpms around 2k especially with the windows down. Is there any other suggestions on what to try? I like the sound outside but wish it was quieter inside.

^ Skyfox16, alot of owners of a 4.7 go with the Flowmaster 70. Search for 'Kolak exhaust' and read the reviews. He also offers Jeep forum members a discount.

I would install some sound deadening material underneath the carpet. It cuts noise down alot, and its really inexpensive. 120 bucks for your whole jeep.

I put a Walker Stainless Steel muffler on my wife's ZJ. It's a little louder than stock not obtrusive. No droning down the road. Best part it's stainless. I must have replaced the other aftermarket mufflers every 3 years. Bought it off Advance Autoparts website at a nice discount.

Just a followup - I had the flow master 50 series removed - i don't know if it was the stock piping or what but i had a terrible drone on the highway around 2K rpms which is where the rpms are most of the time on the highway. If i lowered the windows it was even worse. I loved the sound of the 50 but just couldn't take the noise on the inside.

I went to auto zone and picked up a Walker Sound FX Muffler - ended up getting it for $40 and i love it. It is louder than stock but I only really hear it at idle and when accelerating. On the highway its almost completely silent.

I wish i was one of the people saying that the 50 series isn't out inside because i loved the sound outside (but for me it just didn't workout).
