Collection: 2003-2007 5.9L Cummins Applicable Products

Awesome product and very easy to install also the best part about this kit is that it does work with other added on fuel filter AFTER the cp4 so you get best of both worlds🙏🏽

The 5' exhaust with the 6" tip looks and sounds really good. The egr delete its made really nice and fits perfect and looks good.
The ccv it's easy to install it fits and looks good too. Thanks soo mutch

It works great, the nut that rubbed a while in the up pie was moved from the original place and doesn’t rub anymore

Not to easy if you don’t know what your doing\not mechanically inclined, but definitely worth it for the quality love the stuff!

Glad your product is on the market. I love the looks of it and the performance aspect of the intake horn. Glad I chose ya’ll. Can definitely feel the truck breathing better!!!

Overall, great kit. Wish I would have ordered the can bus plugs at the same time. A few modifications were needed to make everything work but nothing too difficult if you can tackle this type of work to begin with.

Great quality and fit

Great product sounds amazing

With my old kit that kept leaking, an abnormal seal size and changed colors as the plastic got warm. I installed the Spelab kit and fits good and have the reassurance of the locking ring to keep it in.

Looks good and very good quality

This exhaust set up is amazing and definitely worth the money! Fits like a dream and is not like anybody else’s exhaust! Thank you spelab!

Bolted right up no problem. Highly recommend this intake for the price you can’t beat it.

Great fit and quality. Easy install. Definitely recommend.

Easy install and looks great!

Needed new run TB and didn’t have to measure or cut or adjust the new exhaust! She’s mint now. Will try to add pics of new soon.
