Its transverse configuration places the muffler parallel to the axle, while the single 3-inch offset inlet and dual 2.5-inch offset outlets support a practical dual-exit exhaust arrangement. One outlet is positioned on the same end as the inlet, while the second outlet is located on the opposite end.\u003c\/p\u003e\u003cp\u003eConstructed from high-quality T-304 austenitic stainless steel, the Borla 40474 provides excellent corrosion resistance and long-term durability. Its fully welded construction adds strength, and the free-flow design helps support improved exhaust performance. High-temperature continuous-filament fiber acoustic material provides sound control while maintaining the performance characteristics expected from Borla exhaust components. The natural mill finish may be brushed or polished before installation.\u003c\/p\u003e\u003cp\u003eThis universal muffler features a reversible design for installation flexibility and un-notched necks intended for weld-in installation. When clamping is preferred, use compatible Borla band clamps 18004 and 18006. For an alternative muffler with notched necks, consider Borla part number 400499 with band clamps 18325 and 18330. The Borla 40474 is made in the USA and backed by Borla's Million-Mile Warranty.
