Awesome kit, made a huge difference in power

This kit was well set up with all the parts needed to upgrade the system with. Everything was well built and was a major improvement compared to what was stock on the truck. Any one with the early 99 I would highly recommend this product to up grade.

This kit took my E99 F250 7.3 powerstroke and gave it the ability to breathe and run like it was intended to do. The only issues that I ran across are you need to save your old up pipe clamp or purchase a new one and there was one missing pedestal o-ring. The old clamp broke when taking it off so I purchased a new one and instead of bothering Riffraff with the pedestal o-ring I picked one up from the local ford dealer. Amazing difference in how my truck runs now.

The product was as described. Went with the
Riffraff_Diesel plenums, standard bellowed pipes, and turbo with ceramic coating and bullet wheel. Installed without to much trouble. It is a very tight fit so you must plan out things carefully. Had to cut a few of my pipes back to get the right alognment. Was missing a plug that should of came with the kit. Contacted RD and talked to someone who agreed and would send it out if we wanted. I was able to go to the hardware store and find a proper solution to get the job completely finished and get the truck back on the road. The truck runs great now and I can hear and feel the difference. The turbo is very nice as well. I did, however, think from all of the other turbo reviews I read that it would be louder. Surprisingly, it is just a small background whistle noise and not to loud at all. I was hoping for a little louder sound, but it gives the truck the power it was missing with the old stock turbo. I would buy this again.

This kit is the real deal. The quality and firmest of the components are perfect! The customer service is outstanding as well! It made a huge difference on the performance of the truck as well!

Awesome kit. Included everything I needed, and best of all the parts are OEM and not cheesy chinese stuff. Highly recommended to upgrade your Early 99 turbo system.

Everything is included and seems to work well together. Seems to be a little more turbo lag than the old stock one but once it gets going the power is there! Also added 1.5 injectors and there is a little more smoke than stock. Very happy with it so far.
