Alcohol race mufflers incorporate strategically placed "burn holes" inside the muffler in all of the low-pressure areas to prevent damage from excess methanol fuel from puddling and backfiring on deceleration. Through years of racing and partnerships with leading race sanctioning bodies, Flowmaster has developed these specialty mufflers that have been specifically engineered for race vehicles in organizations such as NASCAR, ARCA, and the W.O.O. sprint car series. These include race mufflers for low ground clearance, special race fuels, packaging restraints, etc.
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.
