LCGP 3" Universal Resonator 3" Inlet/Outlet — 12" Stainless Steel Polished Straight-Through, Deep Tone

LCGP's 3" Inlet Universal Resonator is a 12" straight-through stainless steel performance muffler engineered to refine exhaust tone while offering durable, polished construction for long service life.

This resonator is a compact, universal-fit exhaust component designed to change the sound characteristics of your vehicle without major modification. Built from stainless steel with TIG-welded seams and a polished finish, it pairs with 3" piping and installs inline to smooth exhaust pulses and create a deeper tone. Because it’s a universal part, trimming and welding during installation is expected—professional fitting is recommended for best results and leak-free joints.

How will this resonator affect my vehicle's sound?

The straight-through design is tuned to reduce rasp and harsh frequencies while adding a fuller, deeper exhaust note. It won’t dramatically increase volume the way a full muffler replacement might, but it refines and balances tone across RPM ranges. Expect a sportier character without excessive drone when properly installed.

• Straight-through internal path for cleaner exhaust flow.
• Designed to reduce harsh high-frequency noise.
• Deepens overall tone rather than simply amplifying volume.
• Best results with correct placement and secure welding.

What are the physical and material specifications?

This unit measures 12" overall and accepts 3" inlet and outlet piping for a common universal fit. It’s constructed from stainless steel with TIG-welded seams and a polished exterior to resist corrosion and maintain appearance. The straight-through architecture minimizes backpressure relative to chambered designs.

• 3" inlet and 3" outlet diameter.
• 12" overall length for compact installations.
• Stainless steel body with polished finish and TIG welding.
• Straight-through flow path for performance-oriented exhaust tuning.

How is it installed and what should I prepare for?

Installation requires cutting or modifying existing pipe to fit the 12" unit and welding the joints for a permanent, leak-free fit. Clamps or hangers may be used for temporary mock-up, but welding is recommended to secure the resonator. Because installation involves exhaust modifications, professional installation is advised if you lack welding or fabrication experience.

• Welding is required for recommended installation.
• Professional installation advised for correct fit and safety.
• May need pipe trimming, clamps, hangers, and alignment tools.
• Check local regulations on exhaust modifications before installing.

Who is this for? This LCGP 3" universal resonator suits DIY enthusiasts, custom fabricators, and mechanics who want to tune exhaust sound and reduce drone without replacing full mufflers. It fits projects where space is limited and a polished stainless finish is desired. Choose this resonator if you have 3" exhaust piping, access to welding or a trusted installer, and want a durable, compact component that refines tone and complements performance exhaust builds.
