This 5” downpipe back kit fit absolutely perfect. Could not ask for a better fit and finish of this kit. All the hangers are in the correct location and the clamps supplied are of quality!

Installation was a breeze!

I bought this kit for my 2019 Ford F350, the same kit I bought for my 2014 F250 almost 5 years ago. The first kit I had significantly boosted my power to pull my 5th wheel up I-17.
While I haven’t pulled anything big yet with my F350 I can already feel the difference in power and performance.
VERY happy with my purchase and…no more DEF (garbage!).

Great replacement cover! Looks great and was easy to install and makes it much easier and cleaner to change my differential gear oil!

Easy and straightforward install and works perfectly

As advertised works and looks great

Good stuff, love the kit. Installed it all myself under 6 hours. Now I need to find a way to keep the minimax from getting unplugged when I hit a bump

Intake horn is real nice, block off plate is real nice, gaskets are decent. I removed first 3 fuel lines and the cp3 line and had mine done in about 4hr by myself start to finish. 2012 Cummins. No cel, no issues. Took away a lot of the black smoking. Increased boost noticeably. Five stars.

Good fit, sounds awesome, definitely made a difference, hose clamps could be a little better, holes was off a little for the sensors, but for the price overall good product!

They have great customer service what I order was much better than what I was expecting to receive thank you for guys for everything

This was a very easy install, the parts seems to be good quality.

Great products, the updates and revisions to there parts show they care about making things better. 100% would buy all my parts from Spelab.

Directions were not good and there isn’t a heater bolt yet..but the product is great and you can’t beat the price. Happy with the product.

This is a good upgrade. I change the rear differential fluid frequently so now I will be able to drain and refill more easily. Easy install. No leaking. Hardware and gasket included. Very happy

I was impressed with the build quality. And very happy with the cover features: fill plug, drain plug, sight glass, nice paint, cooling fins and machined channels on the inside to direct fluid flow. I also put in some AMSOIL diff fluid. A winning combo. Love that gasket and premium hardware is included. A much better deal than the Banks cover. This cover will cool plenty abd direct fluids where it needs to go. I’m happy with my investment and highly recommend.
