Oshkosh 2021 Show Special Discount

As you may know, we typically offer a very generous Progressive Discount as our show special at Oshkosh every year. Although Oshkosh is going to have some in-person presence this year, we know that choice isn't right for everyone, so we are opening our Oshkosh discount to both virtual and in person customers!

Starting Tuesday, July 20, 2021 and running through Sunday, August 1, 2021, our standard Pick Your Price / Lead time based discounts will remain in effect. For most of our legacy (4 cylinder) systems, that means a retail discount of $300.00 with shipping later in the year or early next year. With our Show Special, we will increase that discount by $100.00 for every five orders placed during this special event as outlined in the table to the right.

How does that work you ask? It's simple: Each and every certified exhaust system ordered with at least a six week lead time from 7/20 through 8/1 counts toward the total. You already know what lead time discount you are getting. Now sit back and encourage your friends who have been thinking about a Power Flow to step up. Once we have 6 orders, everyone gets a bonus discount of $100 taken off their orders. We hit 11, and everyone saves another $100, and so on. The maximum discount this year is $500 for 26 or more orders.

To help ease your financial concerns even further, we are reducing the deposit required to confirm your order to just $1,000.00 from the normal $1,500. This will confirm a production slot at the discounted price and assign a ship date. The remaining balance will be charged one day prior to your system’s scheduled ship date. As has always been our policy, your deposit is 100% refundable should your circumstances change. We believe this is particularly important in these still uncertain times.

A few points to keep in mind:

#1.) The Show Special applies to our legacy FAA Certified 4 cylinder Power Flow Tuned Exhaust Systems only. The LEES (Leading Edge) products are not included in this offer.

#2.) Everyone who places an order while the promotion is in effect gets the maximum discount attained so it doesn’t matter whether your order is the first one we receive on July 20, or the last one we receive on August 1. You’ll still get the full discount shown above based on the total number of orders we receive during this promotion.

#3.) The lead times and ship by dates will, of course, have to be adjusted going forward based on our order backlog and production capacity. There is a minimum lead time of six weeks for kits ordered in this sale. Our product web pages will be kept updated with the current lead times. We will confirm those numbers with you before we process your deposit payment.

#4) Want an exhaust system as fast as possible and still get the show bonus? You'll have to wait a minimum of 6 weeks from date of order until we can ship, but in most cases we should be able to do that. Need it sooner than that? We likely can ship sooner than six weeks, but you won't be eligible to participate in the show special.
