Vibrant Performance 1790 bottle-style resonator 2.25" silver — T304 stainless, straight-through core, 12" length

The Vibrant Performance 1790 bottle-style resonator is a polished T304 stainless steel, straight-through core silencer with 2.25" inlet and outlet that reduces exhaust rasp while preserving flow.

This compact 12" long resonator is engineered to tune exhaust tone without creating restrictive backpressure, making it a common choice for custom exhaust builders, muffler shops, and performance home-mechanics. Its 3.5" diameter body houses a true straight-through perforated core that smooths sound signatures while allowing exhaust gases to pass freely. Finished in a polished stainless exterior, the unit resists corrosion and keeps a clean appearance even in demanding environments.

How does this resonator change exhaust sound without hurting power?

The bottle-style design uses a straight-through perforated core to alter pressure waves and reduce unpleasant frequencies rather than block flow. Because the core is unobstructed, exhaust gases maintain velocity and minimize added backpressure.

• True straight-through perforated core for minimal restriction
• Designed to dampen mid-to-high frequency rasp
• 2.25" inlet and outlet to match common pipe sizes
• 12" overall length with 3.5" body diameter for compact installations

What are the material and build quality details?

Constructed from T304 stainless steel, this resonator resists rust and maintains surface finish under high heat cycles. Welds and mounting flanges are designed for reliable fitment in custom systems and factory-adjacent retrofit projects.

• T304 stainless steel body and internal components
• Polished exterior finish for corrosion resistance and aesthetics
• Robust welds suited for automotive exhaust temperatures
• Perforated core designed to withstand continuous heat exposure

How easy is installation and what fitments does it support?

The 2.25" inlet and outlet are compatible with 2.25" exhaust tubing and slip-fit connectors; the compact 12" length lets it fit tight chassis or mid-pipe locations. It can be welded in place or clamped using standard exhaust band clamps for reversible installs.

• 2.25" inlet/outlet for common aftermarket piping and adapters
• 12" overall length accommodates many mid-pipe positions
• Slip-fit or weld installation options for custom or permanent setups
• Polished finish reduces prep time for visible installations

Will this unit last in street and performance applications?

The choice of T304 stainless and a straight perforated core combines longevity with functional performance in street, track, and project-car uses. Regular inspections will keep the unit performing well in varied climates and driving conditions.

• T304 stainless construction for long-term corrosion resistance
• Engineered core to endure repeated thermal cycling
• Polished exterior helps shed road grime and moisture
• Compact size lowers risk of contact damage under the vehicle

Who is this for: This Vibrant Performance 1790 resonator is ideal for DIY exhaust builders, tuners, and professional fabricators who want to refine exhaust note while maintaining exhaust flow. It suits custom builds, replacement sections, or upgrades where a compact, durable resonator with 2.25" connections and a polished finish is required.
