Decent website. Lacking customer service. Website was easy to order off of but did not have great descriptions of some of the products. I ordered 2 parts. One wasn't right and the description didn't state enough info. The other part I ended up not needing. 2 emails later and about a week's wait and still no response from customer service about sending them back.

Great customer service Great customer service, always got through when I called! The person who answered the phone was able to quickly and efficiently answer my questions. I just installed the kit I bought from diesel ops this weekend and I couldn't be happier!! The only reason I can't give 5 stars is because I ran into to a problem with the tuner, i had to research by my own accord to find out how to make it compatible with my truck. Otherwise 100%

Was pleased with the product but not … Was pleased with the product but not too happy there was no installation instructions to go by for the egr delete portion. Also on the rear EGR cap the brass plug blew out and the customer complained of an exhaust leak. They had no intentions on installing an EGT probe

Response to the diesel ops reply to original post Apparently Chris, you don't remember our conversation . When I called the person I spoke with said they would contact MBRP regarding my exhaust. At no point in our conversation was a faulty hanger mentioned or was the reason exaust came off. It was the wrong exaust that was sent to me. My complaint was for the fact I never heard back from diesel ops and I had to contact MBRP my self. Your trying to make it sound like Diesel ops helped me with my issue when the fact is when you responded to my post at the end of April 2018 was the FIRST time I have heard from diesel ops since my I called about the issue. MBRP and the fantastic sales department is who deserves the credit especially since they have followed up 3times with me since I called them. Just wanted to set record straight! Thanks, Jason E.

not impressed I got the wrong turbo I couldn't tell in the picture but this one is for a later 2004 f350 which has the different pedastool so now I have to get that other one. It's not that I want or need a sinister sticker or diesel ops sticker or shirt or receipt or anything but you figure when you spend 1600$ on a turbo you'd at least get a sticker and a receipt
