The Pro Series mufflers work on all applications ranging from street trucks, diesel pullers and RV pushers to every class of racing on dirt or asphalt. During development, at the dyno and track, the Pro Series mufflers consistently delivered performance that is equal to or surpasses open pipe systems, while dramatically reducing sound levels across the RPM range.
Processing & Shipping Overview
Processing occurs before shipping.
Most in-stock items typically process within 2–3 business days before shipment or pickup. Expedited shipping options affect transit time after an order ships and do not speed up processing.
Made-to-order, special-order, vendor drop-ship, and freight items require additional processing time before shipping. Any extended lead times will be noted on the product page when applicable.
For the most up-to-date order status or lead time questions, please contact sales@smgspeed.com or use live chat during business hours.
