Built with marine-grade T304 stainless steel and a perforated \"true straight through\" core wrapped in sound-absorbing media, the unit minimizes drone and harsh frequencies while maintaining free-flowing exhaust gas passage. Its 2.25\" inlet and outlet make it suitable for many custom and replacement exhaust systems where space and sound control matter.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this resonator lower cabin or road noise?\u003c\/h3\u003e\n\u003cp\u003eThe resonator targets and attenuates mid- to high-frequency exhaust pulses that typically cause drone and rasp. Sound energy passes through the perforated core into acoustic packing, which dissipates noise without forcing gases through restrictive bends, so you get quieter operation with minimal backpressure increase.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePerforated true straight-through core disperses sound waves\u003c\/li\u003e\n  \u003cli\u003eAcoustic packing absorbs disruptive frequencies\u003c\/li\u003e\n  \u003cli\u003eLinear flow path avoids performance-robbing restrictions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this fit my 2.25\" exhaust system and withstand heat?\u003c\/h3\u003e\n\u003cp\u003eYes — the resonator is engineered for 2.25\" inlet and outlet pipes and constructed from T304 stainless steel for long-term corrosion and heat resistance.
