I've read several post on exhaust but most are about getting the truck to sound louder and meaner. However, I'm not out to impress anyone or wake the neighbors. I just want an efficient system that is quiet. I also plan to get a programmer for better shifting and towing. My goal is to increase flow and power.
Any recommendations?

I found a take off from a Harley Edition little louder then a stock that came on my FX4 and looks nicer if you stay with a take off from a 07-08 it will be a direct bolt on no mods... ohh and yes the Harley is more of a glass pack design so I would assume it would help

Walker Quiet-Flow SS Muffler. They have 90-Day Risk-Free Trial Offer

Please let me know your feedback if you decided to install this Quiet-Flow Muffler. I can't still decide if I will go for a Straight Flow Muffler with electric motor to adjust the restriction or go for a Quiet-Flow Muffler.

Hi.

Either stay stock ( it is actually quite efficient and preserves yer low-end TQ, and you already know how quiet it is), or replace just the muffler with the largest MangledFlow oval-body muffler - 22-24". You may or may not need to add a small resonator depending upon any drone experienced.

Towing will exacerbate any tendency to drone form an aftermarket repacement - the stocker simply does NOT drone. I HATE drone, lol.

One other thing you can do if you elect to replace the muffler - replace the factory Y-pipe with a 2.5" in / 3" out, going to a 3" midpipe, then to the Maggie or whatever.

Honestly - the programmer will be providing 99% of the tangible gains - there is no real perf benefit to an exhaust swap - and you risk impacting low-end torque if you don't choose wisely. Not something you'd want to do given yer towing goals.

So - stay stock is my humble recommendation. Redirect the money saved towards a good custom-tuned device ( SCT X4 ). MPT, 5Star, VMP, Troyer, PHP, etc....

good luck
