Built from corrosion-resistant T304 stainless steel, it uses a perforated straight-through core wrapped in sound-absorbing material and a larger chamber than common bottle-style units. With compact external dimensions and a 3\" inlet and outlet, this resonator fits many custom exhaust installs where targeted noise control is needed but flow must remain free.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this resonator reduce exhaust noise without choking flow?\u003c\/h3\u003e\n\u003cp\u003eThe 1142 uses a \"true straight through\" perforated tube so exhaust gases pass directly through the center, minimizing restriction. Surrounding that core is a larger absorption chamber filled with damping material to attenuate sound waves rather than reflect them, which lowers drone while keeping velocity. The overall design balances sound suppression with performance-friendly flow.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePerforated straight-through core for minimal backpressure\u003c\/li\u003e\n  \u003cli\u003eLarger absorption chamber to reduce mid-range drone\u003c\/li\u003e\n  \u003cli\u003eT304 stainless construction preserves internal clearances under heat\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the physical dimensions and fitment details?\u003c\/h3\u003e\n\u003cp\u003eThe resonator measures an overall 14\" length with a body length of 9.75\" and a body footprint of approximately 6.75\" x 4.5\".
