LCGP 2.5" Exhaust Mufflers 2-Pack — 2.5" Inlet/Outlet, 20" Length, Stainless Steel Resonator, Straight-Through Tone

LCGP 2.5" Exhaust Mufflers are stainless-steel straight-through resonators with 2.5" inlet and outlet and a 20" overall length, sold as a 2-pack for universal fit on 2.5" exhaust systems.

These LCGP mufflers are built to add a deeper, cleaner exhaust tone while preserving exhaust flow and resisting corrosion. Constructed from stainless steel with TIG welds and multilayer internal materials, each resonator is sized to suit 2.5" piping and installs via clamp or weld. They are designed to reduce rasp and harshness without the heavy backpressure of restrictive chambers, making them a practical upgrade for pipes, mid-pipes, or custom exhaust builds.

How will this muffler change my vehicle's sound and performance?

The straight-through resonator focuses on smoothing high-frequency rasp and producing a fuller, throaty note rather than boosting volume dramatically. Because the core allows uninterrupted flow, you avoid the significant backpressure that can hurt performance on many engines. The CRF and layered construction specifically tame harsh tones while keeping free exhaust velocity.

• Produces a deeper, cleaner exhaust tone without excessive boom.
• Straight-through flow helps maintain exhaust velocity and engine breathing.
• CRF layers reduce rasp and high-frequency noise.
• Suitable for diesel or gas engines using 2.5" piping.

What are the exact dimensions and fitment details I need to know?

Each muffler has a 2.5" inner-diameter inlet and outlet, a 14" body length, and a 20" overall length, with a 4.5" round body width. There is no left/right difference—both units share identical inlets and outlets for straightforward installation. They are universal for any exhaust with 2.5" piping but require a clamp or welding to secure.

• Inlet (ID): 2.5" — fits 2.5" exhaust pipe.
• Outlet (ID): 2.5" — no taper or offset difference.
• Body length: 14"; Overall length: 20"; Body diameter: 4.5".
• Sold as a 2-pack for dual installations or spares.

What materials and construction features ensure longevity?

These resonators are made from stainless steel to resist rust and corrosion in wet or salted-road conditions. The TIG-welded seams and four-layer internal assembly improve durability under heat and vibration, while the Continuous Roving Fiberglass (CRF) media helps dampen noise without disintegrating quickly.

• Exterior: stainless steel for corrosion resistance and long life.
• TIG welds provide robust, heat-resistant joints.
• Four-layer internal construction for vibration strength and noise control.
• CRF dampening material reduces high-frequency noise over time.

How easy is installation and what tools are required?

Installation is straightforward for anyone familiar with exhaust work: the resonator fits over or into 2.5" pipe ends and can be secured with clamps or welded for a permanent connection. Welding ensures the cleanest, leak-free seal; clamps allow quicker fitment and future removal. Professional installation is recommended if you lack welding experience or exhaust-specific tools.

• Fits directly to 2.5" exhaust pipe — clamp or weld-compatible.
• Welding recommended for permanent, leak-free attachment.
• Clamps acceptable for temporary or adjustable setups.
• Requires basic exhaust tools, cutter, clamps, or welder for installation.

Who is this product for: The LCGP 2.5" Exhaust Mufflers are aimed at DIY enthusiasts, mechanics, and hobbyists who want to refine exhaust tone and reduce high-frequency rasp without sacrificing flow. They suit cars, trucks, and custom builds running 2.5" exhaust piping that need durable stainless construction and a straightforward, universal resonator solution. If you want a reliable mid-pipe resonator that balances sound control with performance, these 2-pack LCGP mufflers offer an affordable, long-lasting option.
