LCGP 2.5in Universal Exhaust Resonator - 16in Stainless Steel Weld-On, Straight-Through Deep Tone

The LCGP 2.5" inlet & outlet universal resonator is a 16" weld-on, straight-through performance muffler built from stainless steel to deliver a deeper exhaust tone and reduce drone while fitting many custom installations.

This compact, bolt-in-optional resonator is engineered for tuners, fabricators, and performance-minded drivers who want a refined exhaust note without swapping an entire system. With 2.5" inlet and outlet ports and a 16" overall length, it offers a straightforward, straight-through flow for improved sound character. The polished stainless-steel shell and TIG-welded seams provide lasting corrosion resistance and a clean appearance when installed under the vehicle.

How does this resonator change exhaust sound?

Its straight-through internal path minimizes backpressure while smoothing high-frequency tones, producing a deeper, fuller exhaust note without overly increasing volume. Designed to tame rasp and resonance, it can reduce undesirable cabin drone on many setups.

• Creates a lower, richer exhaust tone instead of harsh whine.
• Straight-through design preserves flow for performance engines.
• Short 16" length targets midrange frequencies for balanced sound.
• 2.5" ports match common cat-back piping for easy fitment.

What materials and finish does it use for longevity?

The body is constructed from stainless steel and finished with a polished surface to resist rust and maintain looks over time. TIG welding reinforces the seams for greater durability in high-heat exhaust environments.

• 304-grade stainless steel shell for corrosion resistance.
• Polished exterior for a factory-fresh appearance.
• TIG-welded seams for strong, leak-resistant joints.
• Robust construction suited to regular road use and performance driving.

How is it installed and what tools are needed?

This resonator is a weld-on unit, so professional installation or experienced DIY welding skills are recommended for a secure, leak-free fit. It can be cut into existing piping or welded to custom exhaust sections to achieve the desired routing and clearance.

• Welding required—MIG or TIG recommended for best results.
• Standard exhaust cutting and alignment tools needed (saws, grinders, clamps).
• Fitment commonly to 2.5" exhaust piping; adapters may be used for other sizes.
• Professional installation ensures proper clearance and sealing.

Will this fit my vehicle and affect performance?

The universal 2.5" inlet and outlet and the compact 16" length make it compatible with many aftermarket and custom exhaust systems. Because the design favors straight-through flow, it preserves engine breathing and typically avoids significant horsepower loss when installed correctly.

• Universal fit for many cat-back and custom systems with 2.5" tubing.
• Minimal impact on flow—maintains performance while refining sound.
• Adapters or clamps can help mate to non-matching tubing sizes.
• Check fitment for clearance to bodywork and suspension components.

Who is this for: The LCGP 2.5" universal resonator is ideal for car and truck owners, custom exhaust fabricators, and performance enthusiasts who want a cleaner, deeper exhaust tone without replacing an entire system. Choose this resonator if you have 2.5" piping or plan a custom install and value durable stainless construction, polished aesthetics, and a straightforward straight-through design. Note: welding is required, so factor installation method and local regulations into your purchase decision.
