Deal alert: These deals can change at any time without notice! Prices, discounts, coupons, and availability may vary by location, account, size, color, or seller.

JEGS is advertising 10% off all Dynomax products and 10% off select Sanderson headers in its October 22, 2026 exhaust promotion. Both offer links lead to the retailer’s instant-rebate collections, making these useful places to compare eligible exhaust parts for your project.
There is also a separate $40 future-order coupon when you spend $350 or more on qualifying merchandise through October 25. That reward is for a later purchase; it does not take $40 off the order that earns it.
Shop the two 10%-off exhaust offers
| Offer advertised by JEGS | Scope | Direct shopping link |
|---|---|---|
| 10% off Dynomax | The email says all Dynomax products; check the selected item’s rebate and final price. | Shop Dynomax instant rebates |
| 10% off Sanderson headers | Select headers only. Match the part number and application before ordering. | Shop eligible Sanderson headers |
JEGS explains that instant rebates apply immediately to the order. Some discounted prices appear only after adding the item to your cart. The email does not supply individual prices or a specific end date for these two 10%-off offers, so check the current discount on the part you select.
The broader email also showcases Borla, Flowmaster, Magnaflow, Pypes, Hooker and other exhaust options. That does not make every featured brand part of the two 10%-off promotions above.
Earn a $40 coupon with a qualifying $350 order
The JEGS Bounce Back Deal runs October 19–25, 2026, ending October 25 at 11:59 p.m. Eastern. Your qualifying merchandise subtotal must be at least $350 after discounts, excluding shipping, taxes and gift cards. No registration or special code is needed to qualify; guest checkout customers can participate.
JEGS emails a unique, one-time-use $40 code after the qualifying order is placed. Redemption starts October 26 and runs through November 15, with the code expiring November 16, 2026, at 3:00 a.m. Eastern. There is no minimum purchase to redeem it, but unused value is forfeited.
The coupon is valid on eligible new online orders at JEGS.com, including sale and clearance merchandise. It excludes gift cards, shipping, taxes and applicable fees; it cannot be combined with other promotional codes, exchanged for cash or applied retroactively. Your original order must remain above the qualifying threshold after returns, cancellations or adjustments. Redeemed codes are not automatically restored after cancellation, and expired codes are not extended.
How to shop without mixing up the offers
- Use the Dynomax or Sanderson collection link and check the exact part’s vehicle, engine and installation requirements.
- Confirm the instant rebate in the product details or cart. The email does not give a coupon code for these two brand offers.
- If you want the bounce-back reward, verify that eligible merchandise still totals at least $350 after discounts. Do not count shipping, taxes or gift cards toward that threshold.
- Review stock, shipping charges and your final total before placing an order.
- For a qualifying purchase, keep your emailed $40 code private and use it during the stated future redemption period.
A separate “Trick or Treat Your Ride” banner in the email gives the public code TREAT26. The email does not state its discount amount or complete eligibility, so check the JEGS coupon-savings selection and current terms before using it. Do not assume that code applies to the Dynomax or Sanderson offers or combines with another code.
Fit and shipping: Compare the exact part number, vehicle application, engine, pipe size, finish and included components before buying. The promotion does not establish compatibility or promise free shipping for every order. Check the selected listing and checkout for delivery charges and availability.
