Driveway exhaust modification

[SupremeWill]

I installed a 14" Magnaflow with offset 3" inlet and outlet part number 13239. It was super easy and cheap and I did it in my driveway.
All you need is the muffler, a short piece of 3" pipe approximately 14" long and belled on one end, and three 3" exhaust clamps. For tools you just need a metal saw, ratchet with 15mm and 16mm, and a pry bar to pop off the rubber hangers.
The muffler is offset on both ends so it lines up perfect and no pipe bending is needed. I cut approximately 2" in front of the muffler and 1" behind the muffler. Everything goes together super easy if you unbolt the remaining front piece of fact exhaust pipe, put it all together then rebolt it. If your tips are not sticking out equally then rotate your muffler till they are, this help adjust the rear piping.
All together this cost me about $110 and it sounds great.

How are you supporting the muffler? Did you use a strap?

Any pictures?

Video of sound and how it looks underneath if possible please.

Let me figure out how to upload and I will get ya taken care of.

Currently no additional support. The new muffler is much lighter than the factory one.

Exactly what I have! Sounds good, not too loud while cruising but a nice rumble while accelerating
EDIT: mine isn’t quite exact, part # 14239, 5x8 oval, 14” muffler length, 20” overall, just to clarify. Thanks

Nice! What bed cover do you have and do you recommend it?

It is a EXPRESS tonno, a soft roll up with the velcro sides. I do like it. I have had these kind on other trucks. Only part I don’t like is the back only latches on one side. It is spring loaded and self adjusting and seemed a bit loose. A couple times on extremely windy days it would become unattached in the back at the lever. I simply bent the lever handle to hold the cover tighter and it seemed to have worked. Just wish it had a latching lever on both sides instead of just one.

I did the exact same with the Flowmaster Super 44 muffler. The key is getting offset inlet and offset outlet so you can use a straight pipe extension. I used a 3" x 14" stainless. The hanger needs to be mounted to the pipe just behind the muffler.
Easy, cheap, sounds great, deep rumble, not too loud, enjoyable.
