Alpha 500-Cell Catalysts
SPD's industry-first Alpha catalytic converters outflow standard 400-cell performance cats by +90% while meeting modern EPA requirements. Each converter is loaded with Rhodium, a platinum-based alloy that reduces NOx emissions — something no other high-flow cat can claim.
The result? Cooler exhaust temps, faster turbo spool, and smoother power delivery — with no tuning required and zero check engine lights.

The HX Series completely transformed my truck. Deep, aggressive tone at WOT but absolutely zero drone on the highway. My wife doesn't complain anymore. Best exhaust I've ever owned — and it's made right here in the USA.
SPD Performance FAQ
What's the difference between HX and GX Series?
The HX is deeper and quieter with Helmholtz resonator technology — perfect for daily drivers. The GX is louder and more aggressive — designed for enthusiasts who want maximum presence. Both flow identically.
Do SPD downpipes require a tune?
No! SPD downpipes use Alpha 500-cell catalysts that maintain proper O2 sensor readings. Direct bolt-on replacement with no custom tuning required.
Will I get a check engine light?
SPD's Alpha cats use Rhodium-loaded substrates that exceed EPA requirements. No CEL codes on properly maintained vehicles.
What makes SPD mufflers different?
SPD uses proprietary hard-pack sound dampening that won't break down over time. Cheap "loose pack" mufflers degrade from vibration and blow out — SPD's design lasts for years.
Does FFP install SPD products?
Absolutely! Our technicians have extensive experience with SPD systems. Professional installation with proper torque specs and leak testing included.
What performance gains can I expect?
SPD Alpha downpipes typically add 15-40+ WHP depending on supporting mods. Combined with a quality tune, gains can exceed 50+ WHP.
