Customer Reviews
Overall rating: 4.6 / 5 from 37 reviews.
Getting the stock parts off was a bit of an issue... not much room! Lol! and pretty sure original nuts were cross-threaded on the exhaust system. I had to rethread one exhaust clamp I needed for the tailpipe connection.
The installation of your supplied exhaust replacement system very extremely smooth!!!
If there was one thing I would like more practice on - or perhaps better videos of... is how to disconnect the factory plugs.
Thanks!!

The kit does not come with the plug for the def. Also there's no instructions saying which plugs go where. I emailed Sales to get more information but they did not reply.

This kit worked well no issues, but it did not include the DEF tank and also did not include throttle valve regulator delete plugs.

I think the kit should come with all the plugs to do a delete and not have to purchase a separate kit for the def tank

I bought these to ensure that my connectors stay clean and free of road debris. I have no plans of using them again, but these plugs are a great piece of mind to have on the truck. They fit great and are easy to install!

Exactly as discribed. Every plug fit perfectly. Would give five stars if there was a quide as to what all plugs were for. Otherwise great product and much needed when doing a quality delete.
