Fantastic kit! After installing the DEF delete Cummins kit, I cleared my exhaust filter, and the truck runs like a beast. Power and fuel efficiency have both improved.

Solid product. Easy to install, and everything worked as expected. The only downside is the packaging could have been better, as some parts were slightly scratched.

I've been using the DEF delete kit for a few days now, and it definitely boosted my truck's power. I did have a little trouble with the installation, but overall, I'm happy with the product.

This DEF delete kit cleared my exhaust filter and made my Cummins feel like a whole new truck. I've seen an increase in power and an improvement in MPG, so I'm very pleased.

Great kit overall! The EGR delete and exhaust made a noticeable difference in performance and fuel economy. The only reason I�m giving 4 stars is that the tuning took a little longer than expected. Still, the results speak for themselves�my truck runs way better now.

This EGR delete kit completely changed my truck's performance. The turbo spools quicker, and I've noticed a nice improvement in fuel efficiency.

The product itself is great, but there was a slight issue with delivery. It took longer than expected to arrive, and customer service didn't respond quickly.

Took a bit longer to tune than expected, but customer service was helpful. Truck pulls harder uphill now.
