“The mouthpiece on a pipe was too small & they were super quick to get us a return label & got the right piece to us in less than a week. The powder coat looks great & my husband is excited to get them in his truck! We were not upset at all about the mouthpiece sizing issue. They have great customer service.”

“I bought quite a few parts for my LBZ build. Powdercoat came out very nice. Parts were shipped out on time and packaged very well to prevent any damage from occurring during delivery. Performance-wise I’m very happy. My truck is so much faster now with better turbo spool and it sounds good also. HSP is definitely top notch quality and I will be purchasing more in the future”

“Bought the HSP billet manifolds. Explained to Mike @ HSP I was pressed on time and he made sure I got the last available made manifolds due to my situation. I am a repeat customer and will only deal with HSP for all my truck needs. The manifolds make the truck run about 100°F cooler running a 200hp tune, weld beads are nice, ceramic coat is clean. Again, the customer service is the absolute best, they speak English, there isn't a long wait time to talk to a REAL human being, its AMERICAN made and all needed parts come with their products. After my order I realized I needed up pipe gaskets because I didn't read the full description upon my purchase, emailed Mike and I tried to pay over the phone and he just threw them in my shipping box with my manifolds on the house. I can't rate this company high enough. My lift pump, HSP full Y-Bridge, manifolds, CP3 Conversion, CTS3 monitor, PCV re-route kit have all been ordered through HSP amongst other things and I keep coming back not only because the quality is top notch, but the customer service alone and I don't even entertain other companies. Very humble people and they ALWAYS return calls, emails if the phone is busy and have to leave a message. This is the mold of how companies should function.”
