Flowmaster 3 IN(C)/3 OUT(C) Super 10 SS Muffler

The Flowmaster Super 10 is a single chamber 409S stainless steel muffler for the 2015-2023 Ford F-150, and its whole job is sound. Flowmaster builds it for the shopper who wants the loudest and most aggressive note they can find, and the brand says so in as many words. If you want a quiet truck, this is the wrong page.

Why Upgrade to a Super 10 Muffler

Per Flowmaster, here is what the Super 10 brings to the truck:

• Single chamber design aimed at the loudest, most aggressive exhaust note you can find. You will hear this truck coming, and so will everyone else.
• Delta Flow technology, the same patented design used in the other Super series mufflers, which the brand says delivers maximum performance.
• A body built from 16 gauge 409S stainless steel, the material Flowmaster chose for this whole series.
• Fully MIG welded construction, which the brand ties to maximum durability.

Fitment Notes

Fits the 2015-2023 Ford F-150 in Base trim, and the Tremor for 2021-2023. Does not fit the F-150 Lightning, Raptor or Raptor R. The title lists it as 3 IN(C)/3 OUT(C), so the pipe size on your truck's exhaust has to match before anything else. [VERIFY: engine and cab/bed configurations covered within 2015-2023, and whether the inlet and outlet match the factory pipe on your truck or the exhaust has to be cut to suit.]

Install and Honest Talk

Straight talk first. Flowmaster recommends this muffler for off highway use only and not for street driven vehicles, because of how aggressive it is. Take that at face value. On a daily driven F-150 that means a loud cabin on the highway, and whether the truck is allowed to sound like this where you drive is on you to check. This is a sound part. If you are after a subtle note or a quiet cruise, a Super 10 will not give you that.

Install details from the source are thin. It goes in the muffler's spot in your exhaust, and the first thing to confirm is that your pipe matches the 3 IN(C)/3 OUT(C) sizing in the title. What else you need: [VERIFY: install steps, whether it clamps in or has to be welded, hardware in the box, and whether the 3 inch inlet and outlet match the pipe on your truck.]
