Full system with 3” exhaust to the rear axle combined with our Pure Thunder Series Axleback that produces a deep throaty tone with no high pitch rasp or annoying cabin drone. Our complete system can be tailored to work great from bone stock to over 1000 RWHP depending on primary and collector size. Primaries sizes from 1-3/4”, 1-7/8” or 2” (for max effort racing applications) and collector sizes up to 3-1/2” are available.
