FAQ
Q: Will this fit my non-turbo Veloster?
A: No, this is designed for Veloster Turbo and Forte GT with the Gamma 1.6T turbo engine only.
Q: Will I get a check engine light?
A: Likely yes, since this removes the catalytic converter. You'll need an O2 sensor spacer/CEL fix or ECU tuning to eliminate the code.
Q: Is this street legal?
A: No, this is for off-road/race use only. Removing catalytic converters is illegal for street use in most areas and will not pass emissions.
Q: Do I need a tune?
A: Highly recommended. The Gamma 1.6T responds extremely well to downpipe + tune (20-30 HP). Without tuning, gains are minimal (5-10 HP).
Q: What power gains can I expect?
A: With tuning: 20-30 HP and 20-30 ft-lbs torque. The 1.6T is very responsive to bolt-ons. Best results with full exhaust, intake, and intercooler.
Q: Will this fit the Veloster N?
A: No, the Veloster N uses a different 2.0T engine and requires a different downpipe.
Q: Does this reduce turbo lag?
A: Yes! This is one of the best mods for reducing lag on the 1.6T. Turbo spools noticeably faster with reduced backpressure.
Q: Will this work with the stock exhaust?
A: Yes, but you'll need an adapter to connect the 3" downpipe to the stock 2.5" exhaust. A full 3" cat-back is recommended for best results.
For off-road/race use only. Removes catalytic converter - not legal for street use. Will not pass emissions testing. Check local laws before installation. Professional installation and tuning recommended.
