Very good customer service and helped out when I had some questions
Replacement coupler worked perfectly
Item was perfect
Perfect in completing two CAI installations
Very high quality part. Thicker material than you get on a lot of other places parts. Just make sure you take your time and order the correct size. I misread the sizes and thought I had ordered a 3.25 90* and instead I ordered a 3 to 2.25. Live and learn.
Tight fit, works awesome and looks good. Always happy with zzp
