Review: Great sound by Borla 👍 - Excellent sound despite having no tip Installed on a 3.0 Diesel pickup (just replaced the stock muffler). ✔️ Great improve on the acceleration ✔️ yet still has the little backflow that my stock engine needs
Review: Great on a Miata! - Used on an autocross Miata to keep weight and sound down. It works amazingly well and is nice and quiet without even using a resonator. It has a very low key rumble at idle and zero rasp at full throttle. I actually wanted more sound but I’m pleasantly surprised by how quiet it is.

### ⭐⭐⭐⭐⭐ Great sound by Borla 👍
*by M***. on May 10, 2023*

### ⭐⭐⭐⭐⭐ Great on a Miata!
*by J***S on August 18, 2021*

Used on an autocross Miata to keep weight and sound down. It works amazingly well and is nice and quiet without even using a resonator. It has a very low key rumble at idle and zero rasp at full throttle. I actually wanted more sound but I’m pleasantly surprised by how quiet it is.

### ⭐⭐⭐⭐ Nice Sound
*by C***N on July 5, 2021*

Bought these to replace 28 yr old Turbo Muflers (generic brand). I expected the Borla mufflers to be louder but they do have a nice tone when getting on the pedal. At idle, I heard no difference in sound but it depends on what muffler(s) you are replacing. Motor is a 355 SBC.
