V2 Catted 3" Downpipe: GTI / GLI (Mk7/Mk7.5 · MQB) | 400-Cell GESI GEN2, No-CEL

The V2 Catted 3" Downpipe is a hand-built, direct-fit downpipe for the Mk7/Mk7.5 GTI and Jetta GLI. It pairs a high-flow 400-cell GESI GEN2 catalytic converter with fully TIG-welded, back-purged 304 stainless construction — the top-flowing catted downpipe in its class, engineered to run check-engine-light free. Originally a Baun Performance design (GTI Jake) — this is the same catted downpipe formerly built by Baun Performance, now hand-built by Brockett Built. ▶ Watch the Original Build by GTI Jake (Baun Performance) ▶ Why the V2 DP + OEM Midpipe Is the Best OEM+ Setup — GTI Jake Pairing with a cat-back?

Specifications Diameter: 3" Catalytic converter: 400-cell GESI GEN2 high-flow Material: 304 stainless steel Construction: TIG-welded, Argon back-purged, hand-built to order Check-engine light: Designed to run with no cat-efficiency codes on stock-downpipe tunes Flow: Independently bench-tested among the highest-flowing catted downpipes for the platform, while running a denser 400-cell cat than typical 200-cell competitors Why it's built this way Every downpipe is fabricated by hand from 304 stainless, TIG-welded and back-purged for clean internal welds and long service life. The 400-cell GESI GEN2 catalyst is chosen to keep the car CEL-free without giving up meaningful flow — the setup enthusiasts reach for when they want performance without the headaches.
