Product Features:

Our mufflers offer several features, all designed to deliver superior airflow and improved sound quality:

  • Straight-through flow path: This maximizes performance by reducing back pressure.
  • Non-directional design: You can install it in either direction, providing flexibility.
  • Stainless steel construction: Built for durability, these mufflers withstand harsh conditions.
  • Internal mesh and fiberglass: This advanced design absorbs unwanted interior resonance, ensuring a richer, deeper exhaust note.

Why Choose Performance Exhaust Mufflers?

4 inch diesel muffler and 5 inch muffler for diesel are not just components; they are upgrades. With a straight-through design to reduce back pressure, you will experience enhanced performance and a rich, throaty exhaust sound.

And if you want to add the perfect finishing touch to your upgraded exhaust system, consider pairing it with our T304 Exhaust Tip for a complete transformation.


Important Notes:

Be sure to select the correct size for your vehicle whether you are selecting 4 diesel muffler or a 5 inch muffler for diesel and check compatibility with your exhaust system to ensure the best fit and performance. Mufflers do not come with any hardware, you may need to weld it in or provide your own clamps if the exhaust system you are using doesn't have the appropriate "muffler-delete pipe" to directly replace with the muffler.

Great for oily acne-prone skin
Size: 3 Fl Oz (Pack of 1)
I have oily, acne-prone skin, and this sunscreen has worked really well for me. It doesn’t feel overly greasy or too dry, and it sits nicely on my skin without making my face feel heavy. I’ve been using it for a long time, and honestly, it’s the only sunscreen I keep going back to because it works so well with my skin. It feels comfortable for daily use and gives good protection without causing extra breakouts for me.

Great for oily skin!
Size: 3 Fl Oz (Pack of 1)
Definitely leaves white cast, I’m pretty fair skinned, makes me look like a ghost. Just rub it in your hands first, breaks into the mineral so minimize the white cast look. It feels lightweight and as someone with pretty oily skin it does a pretty good job!

Great for Oily, Rash-Prone Skin, But Be Wary of the Residue
Size: 1.7 Fl Oz (Pack of 1)
This sunscreen is a really solid option if you have sensitive, rash-prone, and oily skin like mine. I’ve found it’s one of the few sunscreens that doesn't cause any irritation, which is a huge benefit for me. On top of that, it leaves a truly matte finish, so I don't feel greasy or shiny throughout the day. The only reason I can't give it five stars is that it leaves behind small, dried white bits on my face. They can be a bit annoying and make the application look a little messy. Overall, it's a good sunscreen that works well with my skin type, but the white residue is a definite drawback.

This stuff is magic!
Size: 1.7 Fl Oz (Pack of 1)
I farm and garden. I spend hours outdoors in the summer, and for years, I’ve hated wearing sunscreen because it made my face feel hot and sticky. This sunscreen is none of that. I received a small sample tube of it from the dermatologist and instantly fell in love with it. It goes on smooth and covers well. But the thing I love about it is that I don’t feel like I’m wearing sunscreen once it absorbs into my skin. I forget about it! It doesn’t combine with my sweat and run into my eyes, making them sting. It doesn’t irritate sensitive skin or clog my pores. This stuff is magic and I will be using it daily. It’s not the least expensive sunscreen out there, but it’s worth it!
