Collection: Exhaust Cutout Kits

I took my F 150 to a local mechanic to get the differential cover and gasket removed, the fluid drained and then everything put back together. I didn't want to bother. My mistake. I got the truck back, put a piece of cardboard under the rear differential and determined that it was leaking slowly. I went back to the mechanic, they supposedly fixed it, but the cardboard check failed again. I went back to the mechanic and they told me it was the pinion seal bearing that was leaking. This problem never existed until I had taken the truck to them. I got the truck back in the pinion seal was no longer leaking but I still had a slow leak from the gasket around the differential cover. $400 later in three trips back to the mechanic I gave up, bought the SPELAB cast aluminum cover and the lube locker gasket plus the necessary fluid and did it myself. No leaks since then. I particularly like the little sight glass since I was able to get the fluid exactly to the halfway mark within the sight glass. I should never have gone to the local mechanic in the first place.

Very well made with quality materials and hardware! You will not be disappointed.

SPE ccv reroute is the best bang for your buck and works very well. Easy install and looks great when installed.

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.
