## Questions & Answers

**Q: Does this still let you have back pressure? Or there isn’t any back pressure with this mini muffler?**
A: I doubt it adds much, if any back pressure. It is straight through with some mesh around where it bumps out.

**Q: So is this a muffler or a resonator?**
A: I would call it a resonator. It will round off some of the harsh sounds, but almost nothing to make the exhaust quieter.

**Q: What is the outside diameter of the inlet? Description says inside is 2” but I’m needing the outside dimension please?**
A: Mine was 2.25

**Q: Are the inlet and outlet id different?**
A: -Inlet is 2.5” INNER diameter 
-outlet is 2.5” OUTER diameter 

-yes the inlet and outlet id are different

## Customer Reviews

### ⭐⭐⭐⭐⭐ Recommend assembly and an unbiased review after a year of owning one
*by H***9 on May 12, 2025*

The media could not be loaded. I painted mine with ceramic matte black. Works best when put within an exhaust system. 12 inches or more of pip afterwards for best results. 5/5 will buy again for another bike. Had this for a year now. I bolted mine with 5/16" self tapping metal screws cause ai have no welder. Tight fitting, Sounds 👍 👌

### ⭐⭐⭐⭐⭐ Tiny but Mighty!
*by A***N on January 15, 2025*

I have a 2020 Ford Mustang EcoBoost, and I put a 3” custom exhaust with SLP “resonators” on my Mustang about two weeks before I got this little resonator. To be honest, I wasn’t expecting much since my exhaust setup had quite a bit of drone on the freeway. I had my local exhaust shop install this resonator, and after they put it on and I drove it. I was impressed with the sound. It got rid of like 60-70% of the drone, and I still have that loud volume I love from my Mustang. But it’s not so loud that I can’t have a conversation in my car like before. Definitely scoop this up if you want a loud exhaust but want to eliminate most of the drone!

### ⭐⭐⭐⭐⭐ It’s a muffler not a resonator
*by M***N on June 4, 2025*

This item was very affordable and gets the job done.Build quality is really good also
