We are pleased to offer the perfect muffler solution for building a custom 3.5" exhaust system on your B5 Audi A4/S4/RS4! Engineered specifically for the cramped space underneath the factory rear bumper, this muffler's compact, straight-through design is ideal for those looking to build their own high-flow exhaust system with an aggressive sound. Fabricating a 3.5" Exhaust System for the B5 Audi A4/S4/RS4 can be especially problematic due to space constraints at the rear bumper. Most aftermarket mufflers are simply too long, causing major fitment issues with the rear subframe and sway bar. Since nothing on the market met the space constraints of the B5 Audi A4/S4/RS4 and integrated cleanly with the rear bumper, we built one to fit perfectly! The 034Motorsport Compact 3.5" to Dual 3.0" Muffler provides enough clearance to route a smooth 3.5" bend to the inlet for optimal fitment and flow.
