OE Header vs 3-inch Catless Performance Header
Smaller pipe diameter, steeper bending angles, poor exhaust flow VS Full-length 3-inch mandrel-bent pipe construction with smoother bends for greatly improved exhaust flow
Equipped with a flow-restrictive three-way catalytic converter VS Catless design with a high-flow structure
High backpressure, creating significant resistance to exhaust gas evacuation VS Dramatically reduces exhaust backpressure for smoother exhaust gas expulsion
Slows exhaust gas velocity, restricts turbocharger efficiency, results in sluggish turbo spool-up and delayed response VS Efficiently expels exhaust gas from the turbocharger, enhances turbo response speed, and accelerates turbo spool-up performance
Limits the potential performance of the 2.0T FSI engine, with horsepower and torque unable to be fully unleashed VS Significantly boosts vehicle horsepower and torque, fully unlocking the engine’s performance potential;
Muted exhaust note with no sporty characteristics VS Aggressive sporty exhaust sound that caters to performance-oriented drivers

Frequently Asked Questions
Will this fit my Audi A3 or VW GTI/Jetta?
Yes — specifically designed for:
• 2007–2011 Audi A3 2.0L/2.0T I4 DOHC (except 2007 A3 Ambiente Hatchback)
• 2006–2010 VW Jetta MK5 2.0L/2.0T I4 DOHC (except 2009 Jetta, 2010 VW Golf)
• 2006–2010 VW GTI MK5 2.0L/2.0T I4 DOHC (except 2008–2009 GTI)
Will this trigger a check engine light (CEL)?
Yes — catless downpipes typically trigger a CEL. Using an O2 spacer or Stage 2 tune can prevent this.
Is tuning required?
Not required, but highly recommended to maximize horsepower gains and ensure smooth drivability.
How much horsepower can I expect?
+10–15 HP on a stock setup; more with Stage 2 tune.
Will this change the exhaust sound?
Yes — expect a louder, deeper, and more aggressive tone with clearer turbo spool.
Will this pass emissions?
In most states, no — catless downpipes are generally not emissions compliant.
Can I install this with my stock exhaust?
Yes — fully compatible with OEM and most aftermarket cat-back exhaust systems.
Does it include installation hardware?
Yes — gaskets, bolts, and O2 sensor fittings are included. Professional installation is highly recommended.
What material and build quality does it have?
Made of high-quality T-304 stainless steel with polished finish. CNC-machined flanges and TIG/MIG welded construction ensure durability. Mandrel-bent pipes provide smooth exhaust flow and reduced backpressure.
Attention
Products on this site are for off-road/racing use only and are not legal for public roads where emissions laws apply.
Professional installation recommended. Removing emissions equipment (DPF, CAT, SCR, DOC) requires deleting related sensors and a compatible tuner to avoid engine codes.
