Leadgee 2.5" Inlet/Outlet Stainless Resonator Silencer 2.5" ID — 18" Body, 22" Overall, Moderate Sound

Leadgee's 2.5" inlet/outlet stainless resonator muffler is a 22" straight-through exhaust component engineered to reduce drone and refine tone while fitting a wide range of aftermarket exhaust systems.

This resonator combines a 2.5" inlet and outlet with an 18" body length (3.5" round core) inside a 22" overall shell to deliver a consistent, moderate exhaust note without overly restricting flow. Constructed from mirror-polished stainless steel and fully welded for durability, it is built to resist corrosion and moisture buildup. The unit is offered as a universal-style resonator for direct-weld installations, suitable for custom exhausts, repair projects, or upgrades where a controlled tone and longevity matter.

How will this resonator change my vehicle's sound?

The Leadgee resonator smooths harsh frequencies and reduces in-cabin drone while preserving the natural engine tone. It’s tuned to moderate the mid- to high-frequency rasp rather than act as a full silencer, so you retain responsive exhaust character without excessive loudness.

• Straight-through design for minimal flow restriction and cleaner tone
• 3.5" round 18" body targets drone reduction across common RPM ranges
• Mirror-polished stainless helps dampen resonance and resists corrosion

What are the exact dimensions and materials I need to know?

This resonator features a 2.5" inner-diameter inlet and outlet, an 18" body length, and a 22" overall length with a 3.5" round body profile. It’s made from stainless steel rather than aluminized steel for improved long-term corrosion resistance and a polished finish that holds up to road exposure.

• Inlet/outlet inner diameter: 2.5"
• Body length: 18"; overall length: 22"; body diameter: 3.5" round
• Material: mirror-polished stainless steel, 100% welded construction

How easy is it to install and what mounting options are there?

Designed as a universal resonator, this part is intended for direct-weld installations and is straightforward for any shop or DIYer comfortable with exhaust welding. Because it’s a straight-through tube, you can cut and weld into existing lines or use clamps and adapters for temporary fitting before final welding.

• 100% welded body for strength and leak-free performance
• Direct-weld installation—cut-in and weld to existing pipes or use reducers/clamps
• Universal fit for custom systems, replacements, or performance upgrades

What maintenance and lifespan should I expect?

Stainless construction and full welds reduce corrosion points and slow moisture-related wear, so the unit typically outlasts aluminized alternatives under normal driving conditions. Periodic inspections for weld integrity and hanger alignment are recommended to maintain fit and finish.

• Stainless steel resists rust and road salt better than aluminized steel
• Inspect welds, clamps, and hangers annually or after heavy use
• Leadgee provides a 12-month coverage period for manufacturing defects

Who is this for? This Leadgee resonator is suited to car and truck owners, custom exhaust builders, and mechanics seeking a durable, moderate-sounding resonator for performance or repair work. Choose this part if you want a stainless, straight-through component with a 2.5" inlet/outlet, a 3.5" round body, and a balance between sound refinement and exhaust flow for street-driven vehicles.
