What our customers say about HPC

“I just wanted to let you know that the pistons you coated for us are working great. We are running an outboard powered rag boat in the Deep South Racing Association’s Unlimited class. We use a 153 C.I. Mercury V-6 with nitrous oxide that produces 475 H.P. at 9,800 RPM. Your coatings allow us to produce more horsepower and increase reliability. Also, the quality and workmanship of your products is far superior to that of your competitors, event he factory Mercury pistons. With one race of the seven event series remaining, we have three 1st, one 2nd, and one 4th place finish. I feel that HPC coatings are definitely part of our winning edge. I would definitely recommend your products to racers and anyone interested in improving the reliability of their engine.”

“I received my headers today at the race shop, they were packaged perfectly. Now that they are unwrapped they just look GREAT! Thank you very much for the detail from start to finish.”

Skip S.

“I wanted to let you know how happy I am with the coating you placed on my Banks headers. As you know I made the investment to purchase a top quality exhaust system for my truck, Banks engineering builds a superb product. My interest in your product was to preserve my investment and keep it looking as good as I could with the added benefit of heat retention. However after installing the exhaust system with the coating applied to the headers and cross over pipe I found the heat retention of the coating to be amazing! I was in the process of checking the header bolts after I had run the truck for a few days. The truck had been running for several minuets and I was able to rest my hands on the header pipes without any problem. However when I touched the EGR tube I was in for a shock, it was very hot. I was amazed at the difference in temperature between the EGR tube that exits the header and the header tube itself.

Nice job! I’ll be sure to pass the word.”

Bryan S.

“I received my valve cover today from UPS, and I must say, I did not expect the valve cover to come out this good, it by far exceeds my expectations.  Your company did an excellent job on this valve cover and I will definitely pass on the word, I’ll be taking a picture of it tomorrow and I’ll send you one, it looks amazing.”

Aaron L.

“I have a Thunderheader on a Road King that has over 110,000 miles on it (the bike and the Thunderheader), and the coating is still in great shape.”

Chris D.

“I just wanted to write to let everyone at HPC know how satisfied I was with your product and service. Before choosing your company I also contacted one of your competitors and to this day have yet to receive any tech support.  I contacted your company with questions about your products and received a response in less than 10 hours from Cory Ure.  Once I had shipped my parts out to HPC Central Steve Dekker and Brian Neil did an excellent job answering my questions. Thanks for all of the wonderful and timely support.  I will definitely recommend your company and products to all of my friends.”

Duane K.

“I’m very impressed with your company and the great customer service (rare these days).”

Gary L.


A few years back I had you guys coat some ASM headers for my LT1 Impala.  They were done in RED and 40K miles later they still look RED.”

Rob W.

“The black coating on my Vance and Hines pipes receives a lot of praise at the rally in Faakersee, Austria (European Bike Week)...  I can honestly say that your coating has held up well for 10,000 miles, very little cleaning, and I only got around to using your cleaner and polisher once.”

Bill P.

“I just wanted to follow up with the 2 gentlemen that I spoke with while I was in attendance at the International Auto Salon in Long Beach this past weekend… Thank you for taking your time to speak with me, it only reinforces the great customer service that I have already experienced.”

Austin G.

“We assembled our racecar with our new, coated header pipe. We feel like it accentuated the looks our racecar and certainly added horsepower. I’ve attached a pic of the racecar to show how well the FTZ header pipe looks. We have gotten several inquiries as to who did ours.

I wanted to pass on a “Thank You” to the staff of HPC. Plan on seeing more of our pipes this winter.”
