Ordered the Y-Bridge and intercooler tubes, used the truck towing heavy load over the weekend. Huge improvement in power and fuel mileage. Customer service was good. Took a little too long to get the parts (about 6 weeks) but they are good quality and fit well.

Nothing but good stuff from you guys. From product to keeping me informed on what is going on with whatever I order

Never got my cap I irdered

Great products

Kit looks great have 0 complaints

Everything fit well and looks amazing

Great job. They did what they said they would. Nice orange pipe. Had to replace there 4 inch boot on the lower end with a 5 inch boot from PPE. Fits much nicer with the longer boot.

Excellent company to deal with. Product arrived well wrapped and protected from damage. My order arrived earlier than expected and was a perfect fit. I will definitely purchase from them again.

great customer service and great product no complaints at all. kept me updated throughout the whole process on my deluxe kit

Super happy with everything I’ve ordered. Love the color and shipping was a breeze

Shipped timely and was professionally packed. Some would say the best packing job ever, that's what I would say I noticed. Smooth powder coating as well. Looks great.

HSP was great to work with only problem I had was my core return to longer than expected and we had a little argument cuz they sent back the wrong amount and was a key stroke rate but they fixed for fast no problem and apologized for the mistake I have and will continue with to recommend HSP to friends

Awesome thank you

Product was mid grade. Customer service was good with updates. I am disappointed with the intake

Top notch customer service and help from the sales team. Mike was awesome to work with and Blair kept me in the loop with the progress of my order 10/10 highly recommend HSP Diesel!!

Exactly what you said

They are awesome to deal with an have great products

I had some confusion with the shipment date, but they were very helpful and great to work with not only do I recommend HSP for how great they are to work with but the product itself was amazing. I got a new white bridge, hot and cold side charge pipe and new up pipes.

Shipping was fast powder coat was flawless. They did a great job

Website could use some fixing, customer support is pretty good though.
