LCGP 3" Ultra Quiet Resonator - 3" Inlet/Outlet, 14" Overall Length, 304 Stainless Steel, Oval Quiet-Flow

LCGP's 3" Ultra Quiet Resonator is a universal 3-inch inlet/outlet stainless steel oval muffler engineered to reduce exhaust noise while preserving free-flow performance.

This resonator is a straight-through, 304 stainless steel unit with a 3" inner-diameter inlet and outlet, a 10" body length and a 14" overall length. Built with a larger internal sound-absorbing chamber and an oval body profile, it balances quieter cabin sound with preserved exhaust velocity for a deeper, refined tone. The universal fit makes it compatible with any 3" exhaust piping; professional welding is recommended for best results.

How does the LCGP 3" resonator change my vehicle's sound?

It tones down harsh resonance and drone while keeping a controlled, throaty exhaust note. The straight-through core minimizes backpressure so performance feel is retained while reducing unwanted frequencies.

• Large internal chamber for broader sound absorption
• Straight-through flow preserves exhaust velocity
• Oval shape smooths tone without making it artificially loud
• Reduces cabin drone at cruising speeds

What are the important dimensions and fitment details?

The resonator features a 3" inner diameter inlet and outlet, a 10" body length, and a 14" overall length. There is no difference between inlet and outlet orientation, making it easy to orient during installation.

• Inlet & outlet: 3" inner diameter (universal fit for 3" pipe)
• Body width options indicated: 5" / 6.8" (oval profile)
• Body length: 10"; overall length: 14"
• Welding or professional installation recommended for secure fit

What materials and construction ensure durability?

Constructed from 304 stainless steel, this resonator resists corrosion and maintains structural integrity under heat and road conditions. The robust build provides long-term resistance to rust and wear compared with standard mild-steel units.

• 304 stainless steel shell for corrosion resistance
• Welded seams for long service life (professional welding advised)
• Oval outer profile to resist road debris and deformation
• Designed for repeated thermal cycles without rapid deterioration

How easy is it to install this resonator on my vehicle?

The universal 3" inlet/outlet makes this unit suitable for any exhaust system using 3" tubing. While it’s a straightforward mechanical fit, welding is the preferred method to ensure an airtight, durable connection; clamps or hangers can be used for temporary or test fits.

• Universal 3" fit works with standard 3" exhaust pipe
• Can be clamped for trial positioning; weld for permanent install
• Orientation-independent inlet/outlet simplifies alignment
• Professional installation recommended for best sealing and longevity

Who is this for: The LCGP 3" Ultra Quiet Resonator suits enthusiasts and technicians who want to reduce exhaust drone and refine tone without sacrificing exhaust flow. It's ideal for street cars, light trucks, and custom exhaust builds using 3" pipe where longevity and corrosion resistance matter. Choose this resonator if you need a durable, stainless-steel solution that provides quieter operation and maintains a performance-oriented sound profile.
