Since the HPI Shorty pipe was the top performer out of all the 2-1 Shorty pipes we tested, we were curious to see how the HPI Full Length 2-1 would do. The exhaust systems from HPI are hand made here in the USA with the highest level of detail compared to many of the other options on the market. They are also the most expensive systems currently on the market and have a wait time of several weeks once you place your order. So of course, we all want to know if they're worth all the hype. Short answer - yes. These pipes are badass and craftsmanship is second to none. Check out the sound clips and final Dyno numbers of this Full Length pipe on our stock 2020 Road Glide.

We had previously upgraded the stock air cleaner to an Arlen Ness Big Sucker which did manage to add some hp/tq with the added air flow.

If you're looking to upgrade your 2017 or newer Harley Touring exhaust, but need some help deciding which pipe you want, be sure to checkout either our Youtube channel or scroll threw these next few blog for photos and video sound clips. We've tested some of the more popular systems on our stock 2020 Road Glide to see how they perform.
