Product Overview:


FlowFX Muffler - 3.00 Center In/ 2.50 Dual Out - Straight Through Performance - Moderate Sound - Stainless Steel


  • Flowmaster quality
  • Straight through design
  • Moderate exterior performance tone
  • Durable fully welded 409S stainless steel case

Flowmaster's FlowFX series mufflers deliver a moderate performance tone for the enthusiast looking for an exhaust note that is different from the "chambered" muffler sound. The interior features a large 3.00-inch "straight-through" stainless steel perforated core, surrounded with high-temperature sound absorption materials delivering a deep traditional mellow tone. The internal flow design is reversible, so the muffler can be installed in either direction to best suit the vehicle application and offsets needed. Features include fully MIG-welded "bright" 409 stainless steel construction with the FlowFX logo embossed on both sides of the case. The FlowFX line of mufflers is perfect for the person looking for a show quality performance muffler at an economical price point and in a compact sized case.

Questions & Answers

Will this fit 2017 ram 1500 5.7

Asked by: Ray57
These are generic mufflers designed for universal application. This particular one is stainless-steel and has a 3" inlet pipe and dual 2.5" outlets. If you don't know what you're looking for it may be worth consulting with your local muffler shop for advice.

I have a 1985 GMC High Sierra short bed pickup with single exhaust muffler but has TWO tail pipes exiting out of stock muffler exiting out to the Drivers side behind the drivers rear wheel..Do you have a muffler that will interchange with this one?

Asked by: Nat C
Unfortunately we do not carry an exact replacement muffler for your vehicle. The muffler you need has one 2.5" inlet and two 2" outlets. The body length is 19 inches long and 10.5 inches wide.

Hi There, I would like to purchase the Flowmaster FX. I have a 1999 Corvette 5.7 Litre. will it clamp on without and pipe bending or extra parets and match up to the chrome muffler stock ends? Thanks, Dave

Asked by: salesmanship
As long as your sock muffler is close in dimension it should be a pretty straight forward swap. However, this is not designed to be a direct fit so some modifications may be needed.
