Progressive Discount: For every five orders placed after the first five, ALL customers will receive an additional $100 discount, increasing to a maximum of $500 off. While we can't predict what the final dollar amount will be, we usually reach at least the $200 bonus level and frequently hit the $500 level. Wherever we wind-up, you get the full discount amount reached whether your are sale #1 or sale #26.
Pick Your Price Lead Time Discounts for Four & Six Cylinder Tuned Exhaust Systems: For even greater savings on our Power Flow Systems, we offer discounts based on Short or Long Lead Times. Earliest current ship by date for most systems is 5/22/26 with no Lead Time Discount.
Ship By Dates are subject to change based on production capacity*
Sun N Fun Progressive Discount
As you may know, we typically offer a very generous Progressive Discount as our show special at Sun-N-Fun every year. We know everyone can't make it to the show, so the Sun N Fun discount is open to all orders, placed at the show, called in to our offices, or from our website.
Starting April 4th and running through Sunday, April 19, 2026, our standard Pick Your Price / Lead time based discounts will remain in effect. For most systems, that means a retail discount of $200.00 with shipping in the late Summer. With our Virtual 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, in production, not introductory priced exhaust system ordered (Piper PA12 and Experimental are not included in this sale) with at least an six week lead time from 4/4 through 4/19 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. When we hit 11, and everyone saves another $100, and so on. The maximum discount this year is $500 for 26 or more orders.

Be sure to include SNF Discount in the notes to lock in additional additional discounts earned. Additional discounts will be added to your invoice within ten business days after the end of the sale.
Funding a Deposit
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 ten business days prior to your system’s scheduled ship date. As has always been our policy, your deposit is 100% refundable should your circumstances change.
If you prefer, you can call us with your credit card account info at (386) 253-8833 when you have about 5 minutes to complete the transaction. Please do NOT e-mail your credit card info to us. You can also order through our website and these orders will be included in the discount.
Upon receipt of your deposit we will contact you again to confirm the configuration, ship by date, and applicable discounts for your order. Be sure to include 'SNF 2026 Discount' in the notes to lock in additional additional discounts earned. Additional discounts will be added to your invoice
by April 30 2026.

A Few Points to Keep in Mind
#1) The Show Special applies to our in production, FAA Certified Legacy 4 cylinder and 6 cylinder Power Flow Tuned Exhaust Systems. The Piper Cub PA12 and Experimental are not included in the S n F Sales.
#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 April 4th, or the last one we receive on April 19th. 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 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? You'll have to wait a minimum of 6 - 8 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 can ship sooner than 6 weeks, 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. If and when the deal gets too good to pass up (remember that the Show Special discount is in addition to our standard Pick Your Price lead time based discounts – currently as much as $150 to $300 for most systems), you can just click on the secure, encrypted Payment Link below to place your order or order on our website.
