RAI B5 Audi S4 3.5" Exhaust Sound Clips
Sound clips of our B5 Audi S4 3.5" Exhaust system. This is a purpose built race system designed to work with our 3" downpipes. The system features a dual 3" to single 3.5" collector that allows the merging Exhaust gas to transition with minimal collision. The design also keeps the downpipes need for equal lengths in tact, as needed by the bi-turbo system. A 3.5 inch race muffler is used in the center of the system, then exits via a 3.5" Borla muffler to give an aggressive tone. When paired with our downpipes this Exhaust is good to over 1000 hp, and was designed for Tial turbo upgrades. Materials list is all high quality as usual, featuring 304 stainless steel and counter-bored vband assemblies. For ordering information please visit www.raimotorsport.com or call 443-242-6436.
