Hi everyone...... does anyone here run an AFE exhaust system or muffler on their CTD? I have read that the AFE muffler can be reversed, allowing you to change the sound of the exhaust. I am looking at adding a 4" turbo back system on my '02, therefore eliminating the cat. My concern is that by removing the cat, a straight through muffler will be too loud. I use this truck for work so it can't be super obnoxious. I want the performance benefits of the larger diameter system, but not the excessive noise. A little growl and turbo whine would be great.

Got any suggestions that might fit my needs other than the AFE system? I thought the reversible muffler might give me a bit of flexibility with the sound levels, but I'm sure someone here knows something better that will do the trick.

Thanks!
