FAQs
Q. If I drive my Veloster-N on the track will it void my warranty?
A. The Veloster-N was designed for high performance at home or on the track. The warranty covers
components originally manufactured or installed by Hyundai that are defective in material or factory
workmanship, under normal use and maintenance, regardless if your Veloster-N has been driven on the track
or autocross.

Q. If I modify my Veloster-N will it void my warranty?
A. Performance modifications that alter the engine control and change the air to fuel ratio, ignition timing or
increase maximum boost pressure risk damage to the engine, transmissions and other components. Any
damage caused by such modifications are not warrantable.

Q. Can I use aftermarket parts on my Veloster-N?
A. If the aftermarket part was itself defective or wasn't installed correctly, or modifies the performance as
noted above, and it causes damage to another part that is covered under the warranty, Hyundai has the right
to deny coverage for that part and charge you for any repairs.

Dealer Best Practice
Follow the standard diagnosis and warranty guidelines, regardless if the Veloster-N has been driven on the
track or autocross. Since the Veloster-N was designed for high performance at home or on the track, track
utilization alone does not void the warranty. However, here are some examples of modifications to help
determine warranty coverage:

Examples of modifications that can damage the engine, and which damage would not be warrantable:
· Aftermarket boost relief valve (blow-off) or any other modification to the RCV that defeats the factory
vacuum chamber and solenoid (part of the over-boost failsafe system)
· Aftermarket software programming – ECM (uncertified ROM update that alters the engine control as
described below)
· Any aftermarket modules that splice into the engine harness to change the air/fuel ratio, ignition
timing, or increases maximum boost pressure
· High performance turbocharger
· Additional power adders such as nitrous oxide system (usually removed before warranty inquiry – refer
witness marks of solenoid/bottle mount bracketry and injection holes in the intake system)

Examples of modifications that do not void the engine warranty, unless they cause damage to the vehicle:
· Cold air intake
· Custom straight exhaust pipe
· Oversized intercooler
· Crankcase ventilation oil catch can
· Oversized throttle body
· Oxygen Sensor Adaptors

Hoping for some clarification on this but when it says straight through exhaust and o2 sensor adapters is that referring to a down pipe? I'm wanting to get an high flow catted down pipe possibly but don't want to pull the trigger if I'm interpreting this info incorrectly and risk losing my warranty.

Yes, it IS referring to the DP. I have a cat-less one on the way as we speak.

Best regards,

That's great thank you! Just wanted someone to clarify that for me. So far I've installed Boombaracing solid rear mount, Addw1 catch can, Velossa intake snorkel, AFE momentum, Forge turbo inlet with that 90degree 3inch silicone intake tubing suggested on one of these N forums. Have a Forge intercooler on the way but backordered lol. Haven't decided 100% if I'm going to go downpipe or not but the chunk or torque increase would be nice. Don't want to mess with the rest of the exhaust as I think it already sounds excellent and don't want it insane loud. Trying to pretty much do the warranty safe mods (y)

If you want the car to be more agressive sounding in N mode but keep normal mode quiet, i highly recommended a downpipe. To this day its my favorite mod. The thing crackles like a wrc car at low rpms in N mode and i work night shifts so i dont wake the neighbors in Normal mode.
It didnt change the pitch of the N, but it did make it significantly louder, again only in N mode. Its honestly unbelievable how quiet it remains in normal.

That's nice to know :) I almost always drive in N mode. I don't mind some additional noise as long as not insane annoying or bad drone. What downpipe did you go with if you don't mind me asking? Got any sound clips?

That does sound good! Is there drone on the highway or pretty tame? Notice a little chunk of power increase? Got me more interested now (y) I think I've seen almost every video relating to Veloster N on youtube but it seems not much aftermarket content is being posted yet.

The only drone is in N mode under hard acceleration. If youre just cruising in N mode, theres no drone, and there was definitely a significant power difference

This is somewhat an odd request but I have a base N and am curious if the pops/crackles could be tamed with a dp in normal mode considering I don’t have the valved exhaust. I still get a decent amount in Normal but not the same as when the Engine setting is more aggressive.

Could you try an N custom that has sport+ exhaust but normal Engine setting and see what deceleration etc sounds like so I could have an idea what my Normal might be like?

No video because the rain was trying to kill me, but i can say it is pretty tame. Almost feels like somethings broken honestly because it occasionally crackles but its not like the wrc crackles in N mode lol itll be like a random suprise crackle and just 1. Super strange. Just imagine your exhaust how it is now, but a bit louder
