-I couldn't locate specific information for installing regarding the early 99 powerstrokes, only OBS or Late 99 + models. This may be on me.
-Good quality pipes and fittings. This job is tough even with good parts but these are built with that in mind and will fit once you get everything aligned.
-Make sure to remove the old copper gaskets from your collector. These aren't meant to be used with them and they won't fit with them installed. Seems obvious but hey, mine were so degraded they looked like part of the collector.
-ABSOLUTELY pull your old ones out and compare before purchasing.
-Gaskets for UP pipes de-laminated once taken apart one time. You might considering purchasing a different set of your own, I just threw them back on.
-SAVE YOUR COLLECTOR - the late 99 collector will not work!
-This is the absolute worst job to do solo and especially with the transmission installed. You have been warned.
-Good product overall, and I like that KC makes it clear exactly what truck these fit. Most suppliers aren't going through the trouble of doing that for you.

Very poor fitment. Product is not designed correctly.

I got the 1st stage of the kc300 and has made all the difference in the truck. Also got the pedestal delete and the up-pipes. Has made the truck a completely different truck. On top of the quality product that LC turbos offer they also offer an awesome staff of employees. I don’t know who all was involved but I had a few things come up on my end and kc just was awesome as hell at helping me get everything turned around and went above and beyond for me and it is very much appreciated. Kc turbos knows how to take care of people. I will be back for future parts. Thank u kc.

I’m impressed with the quality. I had a lot of smoke coming from the exhaust when I started my truck in the morning. No smoke, and my boost has increased. Thanks KCT.
