LCGP 3" Stainless Steel Mufflers 3" Inlet/Outlet 20" Length — 2-Pack Straight-Through Resonators, TIG-Welded Durability

LCGP 3" mufflers are stainless-steel, straight-through resonators with 3" inlet and outlet ports, built to boost exhaust flow and give a deep, refined tone in a 20" overall, two-piece set.

These universal-fit mufflers are engineered for drivers who want a durable, no-frills resonator that smooths rasp and supports higher exhaust velocity without excessive backpressure. Made from corrosion-resistant stainless steel and assembled with TIG welding, each unit is designed to withstand road conditions while delivering a fuller exhaust note for trucks, performance cars, or custom fabrication projects.

How do these mufflers affect exhaust sound and performance?

The straight-through core and layered internal construction reduce restrictive backpressure, letting exhaust gases flow more freely and producing a deeper, throaty tone. The internal Continuous Roving Fiberglass (CRF) and multi-layer design tame harsh rasp so the sound is richer without being overly loud.

• Straight-through passage for improved exhaust flow
• Multi-layer interior and CRF dampen sharp frequencies
• Produces a deeper, cleaner tone rather than a high-pitched rasp

What are the exact dimensions and fitment requirements?

Each muffler measures 20 inches overall with a 14-inch body length and 3-inch inside diameter inlet and outlet. The round body width is roughly 4.5 inches; sold as a 2-pack, they are universal for any 3" exhaust piping but will require welding or clamps for secure installation.

• 3" inlet ID and 3" outlet ID for universal compatibility
• 14" body length, 20" total length, 4.5" body width
• Installation via welding or exhaust clamps (professional recommended)

What materials and construction methods make these mufflers durable?

Built from stainless steel, these resonators resist rust and corrosion to extend service life compared with mild-steel alternatives. Skilled TIG welding and a layered internal structure give mechanical strength while the CRF fill reduces vibration and noise for long-term, consistent performance.

• Stainless-steel shell resists corrosion and road salt
• TIG-welded seams for robust, leak-resistant joints
• Four-layer construction with CRF for noise control and durability

Who is this for? These LCGP mufflers suit DIY fabricators, performance-minded drivers, and shop technicians looking for a reliable, universal resonator that balances airflow and sound control. If you have 3" exhaust piping and want a durable, straight-through design to refine tone and support velocity gains, this two-pack provides consistent results for custom systems, turbo setups, or aftermarket replacements. Professional installation or proper welding/clamping is advised for best fit and sealing.
