Flowmaster's latest version of its popular 80 Series Crossflow Muffler has a 2.50 inch inlet and outlet on the same end of the muffler case. This muffler utilizes a smaller 4.0 inch by 9.5 inch by 13.0 inch case for easier fitment on various applications and is intended for use on vehicles where a side exit in front of the rear tires is desired. Delivering a moderate to aggressive tone, this muffler is excellent for custom applications and is constructed with 409S Stainless Steel.
