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.
