Great communication throughout. All post-purchase questions were answered quickly.
This was my first delete install and it went smoothly. After flashing the ECU and removing the old exhaust, only one pipe needed trimming. Everything else fit perfectly. No regrets.
Removing the factory system was the hardest part, especially on the 2017–2019 Colorado. The OEM downpipe required grinding to remove. With proper tools and experience, the rest was straightforward. After 600+ miles, mpg improved from 27 to 32. Next test will be towing a 6,500 lb trailer.
The tuner was delayed initially, but once it arrived the rest of the setup was ready to go.
Installation was straightforward and response time was fast when I needed help. The only downside was hanger alignment being off slightly, but it was an easy fix.
