Customer service was fantastic, they were very communicative about potential delays and responsive to questions, production and shipping was much faster than they had estimated , the installation instructions were easy to locate and very clear

Great quality easy install. Just felt it needed the cut ends taken care of I put oil resistant heat shrink on the ends so they wouldn’t fray

Nothing but the highest quality! My favorite place to upgrade from!

Great product, great company, great service.

Customer service was great, each time when I asked a question got a response within the next business day. The parts I bought are very well built and work as described by every video I have watched about your product line. Wish I had the money to buy more. Just wish I would have got more than one sticker or a banner for my garage like all the unboxing videos I’ve watched lol. On that note the packaging was so nice definitely not a chance of the product hitting or chipping the powder, overall I will be buying more of your products as my build moves forward and potential builds in the future. Thank you, Shawn DQ

Awesome! I had the upgraded bundle kit installed on my 2015 Chevy Dmax. Love the difference it made. Beautiful in Flag Red also. Perfectly made to fit! Thanks HSP Diesel!

Great products, great service

Ordered during the black friday sale. Received all my items. Max air flow kit and Dan's 64mm stage 2 turbo a few weeks later. Started my install in January on my days off. Everything fit together perfectly. Broke down pipe bolts to the exhaust manifolds. So ended up ordering the HSP exhaust manifolds. Easy install and fit great. I ordered it in raw metal. Very little preparation was needed for rattle can paint (rustoleum engine paint chevy orange) let the paint cure for the minimum 7 days. Turned out nice. Customer Service was great. Mike answered all my questions and returned my calls in a timely matter. Helped with any questions about the installation. Ask him for a download of instructions. Yes I would and will do business again with HSP.

Great service and awesome product, thank you guys.

You guys are the best, great product and great people
