## Customer Reviews

### ⭐⭐⭐⭐⭐ 4” to 3” Convertible
*by S***  on January 12, 2025*

This aluminum converter is of good quality and affordable. I would recommend this product/company.

### ⭐⭐⭐⭐⭐ Reducer is good quality
*by J***G on November 28, 2024*

Needed to reduce the 4" liner. Works as expected.

### ⭐⭐⭐⭐ very soft aluminum
*by A***R on July 20, 2024*

this works great, and looks nice, but whatever grade aluminum they used is very soft. trying to use a self tapping screw on it will create a large dent the metal before it drills into it. i recommend pre-drilling your holes.
