This is the full SmartBox build of XForce's Varex cat-back for the Veloster N and i30 N. It replaces the exhaust from behind the catalytic converter back, in 3-inch mandrel-bent 304 stainless steel splitting to dual 2.5-inch pipework, and finishes on the Varex valved rear muffler.
The difference between this and the standard kit is the controller. Instead of the key-fob remote alone, this version ships with XForce's Varex SmartBox Bluetooth controller, which adds smartphone control, fully customisable preset valve positions, and geo-fencing so the car can quieten itself automatically in chosen areas. Bought separately the SmartBox is a $505.99 part, so the bundle is the cheaper route if you want app control.
Features
- 3-inch mandrel-bent 304 stainless steel, splitting to dual 2.5-inch
- Varex valved rear muffler for on-demand sound control
- SmartBox Bluetooth valve controller included
- Smartphone app with preset valve positions and geo-fencing
- Quiet with the valve closed, full straight-through note with it open
Fitment
Hyundai Veloster N, and the i30 N hatch sold under that name outside North America. XForce catalogues this as the i30 N Varex valved cat-back system.
Does not fit: This is the 2.0T N car, not the 1.6T i30 N-Line / Elantra GT, which takes XFES-HY31N-VMKSB-CBS, and not the facelift PDe.4 i30 N, which takes XFESHY36VKCS.
Please note: In N mode the Varex valve must stay between 25% and 100% open, never fully closed. A valved exhaust is loud with the valve open - check your local noise regulations before road use.
Let customers speak for us
Solid shipping ,good communication ,great product 5stars all the way
First let's preface I have tried three other tuners. Not bad mounting or name dropping as they all were solid tunes. But Daniel just has that magic touch when tuning the 1.6 platform.
The car has a buttery smooth power band making the car feel like a larger displacement six cylinder over a turbo charged car. Plenty of fun to be had at any speed or RPM range.
He will take the time to get you dialed in perfectly for your car. No canned tunes here folks. And if you are a EK1 user three tunes for the price of one simply can't be neat.
I received the Stage 2 tune. Here are my thoughts:
- The shifts are buttery smooth
- I love the auto shift @2000rpm when cruising around town; saves me an extra 2-3mpg overall
- Driving in traffic is a dream now, much better than stock. I don't even hear that annoying shifting fork anymore, lol
- Any and all DCT slips are gone
- The increase in torque limit! This opened up my N75 Stage 3 ECU tune; I can feel the difference. The last time I dynoed, I got 289 lb-ft of torque. But it feels much more substantial than that!
- The clamping force is unreal. I did a run from a dig, and it hooked and slammed through the gears all the way to 7k rpm in each gear. Amazing.
Conclusion: This TCU tune is a must-have. If you have an N75 ECU tune, it is an absolute game-changer! Especially with the Redline MT-LV fluid that I'm running. I can't wait to get my retune with water meth injection. Daniel and the rest of the N75 team are the best!
Works like suppose to be fast delivery after installation 5 minutes drive TPMS sensors lights off everything is normal like from factory 👍👍👍

Product was very easy to install and what a difference in shifting also n75 was super awesome to deal with will shop here again
After using the N75 tune for a couple of months, I can confidently say that it offers the best value for your money on the market. I've tried SXTH and LAP3 tunes before, but since switching to N75, I won't look back. With top-notch customer support, it ensures your car performs better, turning heads at every car meet.
Been running stage 2 off that bat and had some problems here and their regarding fueling. Daniel has been with me the whole way, answering questions and adjusting tunes while adding revisions whenever asked. He answers every question I ask even when they don’t relate to tuning.
Highly highly recommend N75!
Daniel's tuning and customer service makes this product a 10 out of 10. I'm new to tuning and he made the process a breeze. I literally laughed out loud when I first drove the car after installing the stage 2 tune. I still can't believe the difference.
Love the intake, fitment is superb, instal was easy and best of all n75’s customer support is stellar and way above average!
