Show Special Progressive Discount
As you may know, we typically offer a very generous Progressive Discount as our show special at Oshkosh every year. And while we would love to see you at our booth, we understand that not everyone can make the trip, so this deal is open to both virtual and in person customers.
This years show special starts Friday, July 4th, and runs through the close of the show on Sunday, July 27th at 5:00 PM, EDT. Our standard Pick Your Price / Lead time based discounts for our legacy four-cylinder Power Flow Systems will remain in effect throughout this promotion. For most systems, that means a retail discount of $300.00 with a ship by date of October 31st (subject to change based on sales volume and production capacity). With our Show Special, we will increase that discount by $100.00 for every five orders placed during the special event as outlined in the table to the right.
How does that work you ask? It's simple: Each and every certified Power Flow, PMCF, C205-C210 exhaust system ordered with a minimum of six weeks lead time from July 4th through July 27th counts toward the total.
Once you place your order, you can sit back, relax, 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.
We will contact every new customer by August 7 with the total discount amount attained, Or - you can join the fun by checking our Oshkosh order scoreboard to see the running total.

Be sure to include 'OSH Discount' in the notes to lock in additional additional discounts earned. Additional discounts will be added to your invoice
by August 7, 2025.
A deposit of $1,500.00 will confirm your order and automatically qualify you for the highest discount level attained during the show. We will schedule shipments based on the order in which deposits are placed. The remaining balance will be due one week prior to your system’s scheduled ship date. As has always been our policy, your deposit is 100% refundable should your circumstances change.
A few points to keep in mind:
#1.) The Show Special pricing applies to our legacy FAA Certified 4 cylinder Power Flow Tuned Exhaust Systems and our new PMCF / LEES products for the six-cylinder Cessna -180, -182, -185, and 205 through 210 series aircraft only. Introductory priced LEES products for the Piper PA -12, -18, -20, & -22 aircraft 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 4th, or the last one we receive on July 27th. 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. 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? Check out the posted ship dates at the time of your order (deposit required). These will be updating as slots fill up. Need the exhaust sooner than that? We likely can ship sooner than the posted dates with an AOG / Expedite Fee, but you won't be eligible to participate in the show special.
You can check on our progress (and the current discount level) by refreshing this webpage whenever it’s convenient.
