Collection: 2003-2007 5.9L Cummins Applicable Products

Fit like crap. As did the down pipe. I got ppe ones and no refund from spelab

Fits very well and is really well constructed. Also looks really good installed in the truck!

Fit, "Like a glove!"

Didn’t have an issue with the install. Instructions weren’t real clear but overall the install was easy. Parts seemed to be good quality.

Fit nice and looks great!

I love it wish I had a tuner for my truck now, but I love it thank you

Perfect fit! I love your products!

I love this intake manifold and heater delete all in one kit, I would put one on every cummins. I got the horn style without the EGR parts and it puts me at ease knowing I'm not going to be getting vaccum leaks at all the block off plates and have to deal with that pesky butterfly valve. This kit really woke up my truck, I wasn't expecting a whole lot of gains but they are definitely there. I run an aftermarket turbo setup, bigger injectors, fully deleted, straight piped (4" but want the 5"), custom tuned, cold air and manual swapped, so like I said I didn't feel it would make a difference but I felt the difference. Love this companies products and am looking to go with there sick valve cover and maybe there 5" exhaust before long.

Great price and works amazing. For the price I thought it would be cheap but it's not its great quality perfect fitment and looks amazing id recommend to anyone thinking about getting rid of the stock one. Worth every dollar

Comes with everything needed. I bought the intake so there was no need for some of this kit so if your buying a intake as well save some money and get the one without the valve delete. Quality parts id buy it again

Worked out amazing with great fitment. With the stock 4 inch downpipe this makes it a complete 4 inch straught exhaust so saves money from having to buy a full 4 inch and sounds the same and ships alot faster

very awesome good fit easy install

Everything worked perfect, the gaskets and caps were all easy to install and sealed great. The pipe was a direct fit. I opted out of the muffler and super happy. Not much drone at all on the highway. And with my tune I went from 16mpg to 22mpg very well priced kit and easy to install

Love it
EASY TO INSTALL

GAVE MY Truck the power that I was looking for .
