Will this bolt straight to my factory cat?

Yes—catback systems connect at the catalytic converter outlet. You'll be working with existing mounting points and flanges on your Colorado. Confirm your vehicle year before ordering.

Do I need to reprogram anything or will a check engine light come on?

Catback exhaust does not affect emissions sensors or engine tuning. No reprogramming needed. Your vehicle will run exactly as it did with factory exhaust.

What's the installation process like?

This is a bolt-on system—no welding, no cutting. You'll disconnect the factory exhaust at the cat flange, unbolt the old hangers, and secure the new catback in place. A jack and basic hand tools are all you need. Plan on 1–2 hours if you're working alone.
