-2.5" inlet / outlet
-offset inlet, center outlet

That's what my V-6 needed, should be the same for all engines though.

The muffler I'm runnin' is called the Thrush Welded exhuast. It sounds the same as a Flowmaster 44, at just under half the price. I am very happy with the sound, as it really improves the sound of the V-6, without being to "rice-y" or obnoxiously loud.

What engine do you have? As that really affects muffler options.

im running the 3.7L V6...Im also trying to stay away from that ricey sound. I like that deep sound the muffler could add.

Does any one know if the flowmaster super 44 still has an "off road" option? I can't seem to find it online..
Also while I got your here, is this the same for the 4.7 v8's as well:-2.5" inlet / outlet
-offset inlet, center outlet

Thank you

At least I hope so.

Thank you for verifying that!!!!! I'll probably pick a super 44 off of Amazon. Hopefully the wife doesn't yell at me for making the Jeep to load haha.
