Description

The cp-e® QKspl™ High Flow Cat Downpipe for the Hyundai Elantra N delivers a serious upgrade over the restrictive factory component. This downpipe is a true performance part — designed from the ground up using 3D scanning and CAD modeling to match the turbine geometry and eliminate flow bottlenecks.

Crafted from cast 304 stainless steel, the QKspl™ bellmouth ensures maximum durability, superior heat resistance, and optimized exhaust velocity. Unlike pie-cut tubing, this design allows for tighter bends without sacrificing wall thickness — perfect for track days, autocross, or spirited street driving.

The 3-inch mandrel-bent tubing connects seamlessly to your factory cat-back system and reuses OEM exhaust hangers and heat shielding for a no-compromise, bolt-on installation. Featuring the EcoF by Gesl high-flow catalytic converter, this unit is CEL-safe and requires no tuning, making it one of the most refined and streetable downpipes on the market.

Every weld is TIG-precise, every curve modeled for performance, and every detail engineered for longevity. This is your go-to solution for more power, more sound, and no headaches.
