OEM system is 70mm, upgraded systems run 76mm such as Remus
Hello, does the GPF replacement affect the guarantee that Hyundai gives for 5 years in Europe? Any inconvenience for installing GPF HDT? Did someone who has it installed the engine failure in the illuminated box? Sorry for so many questions , I want to be sure before I buy it, thanks in advance.
Yes. In any case of failure you could lose the warranty of the whole exhaust line.
In the worst scenario you could lose warranty of the engine.
I had read that oil catch can, intercooler, straight pipe exhaust etc are allowed as per the track warrantee.
So the gpf removal should not affect it. In any case i would be prepared for anything, because.... humans/insurance/manufacturer.

Going to be hopefully removing GPF myself when I get home from work in August before car goes for Ecu tune;
Can anyone who has fitted GPF delete pipes help me out, wondering if lamda sensors (or temp sensors) on GPF are a bugger to remove? Will I need a socket like for removing O2 sensors? If so what size will be needed please?
Thanks.

used a typical spanner, don't remember the sizes unfortunately, however it was a common one.
was way easier to remove those sensors than e.g. the bolts attaching the OPF to the rest of the exhaust

Thanks mate. Although I was hoping the bolts attaching the OPF would be the easier ones!

I was struggling quite a bit, had to use lots of force for the bolts - the sensors on the other hand were quite a bit easier
Hello, I saw another part to replace hdt, would this be worth replacing the GPF model ?, what difference is there between the 2 items that are for the replacement, I would also like to know the original input and output measurements in case of buying the other Article. Thank you

The first item is the flex pipe. Stock flex pipe has 58mm at the narrowest point.
Second item is gpf replace without damper.

My car is gpf version, so it would only be worth the second image since it has the sensors, the first image is for those who do not have gpf but if I already understand resonator, thanks for your help.
That is not correct. Both cars gpf or no gpf have the flex pipe.
It is between downpipe and gpf / mid resonator.

Gentle reminder that visual differences are available here:
GPF vs Non-GPF Exhaust Layouts
Helps a lot when trying to work out what goes where.....
We tend to go around and around in circles in this thread.

The flex pipe and the GPF are two different parts.
Both, the Non-GPF and the GPF-Model have a flexpipe.
The only difference is that the Non-GPF model has a resonator instead of the GPF

Ok I understand, then the flexpipe for the GPF model is also another part as seen in the image, supposedly changing the flexpipe the gain of 7HP, my doubt is if changing flexpipe would pass technical inspection of European vehicles, what gain would it have instead of change the gpf that this would not pass European technical inspection of vehicles. What do you recommend flexpipe or GPF eliminator ?, if you can recommend that it would be ideal to change gpf or flexpipe. thanks and sorry for so many questions.
Changing flex pipe will bring you only improvement on paper.
You won't notice any difference when just changing flex pipe and the rest is stock.
The gpf delete pipe on the other hand will bring most improvement but regarding the law it will be illegal.
I don't know the laws in Spain but in Germany it is not allowed to remove the gpf.
Regarding improvement and emissions. The gpf delete pipe is available in many types
1) Just an empty tube -> the car will be damn loud and probably not pass emission tests
2) With a damper inside -> car will be a bit more quiet than without damper, more recommended if car is driven daily, same with emission tests like 1)
3) With catalyst inside so it should pass the emission test
It depends what your plans are with the car and if you don't have problems with laws and warranty.

As they put change the flexpipe gains 7hp and little improvement in sound, the gpf if it improved the sound but does not put anything gain HP. Here in Spain it is forbidden to replace the GPF emissions tests do not pass, it can only be done in a circuit or closed areas, but here in Spain they also change it and when it touches vehicles technical inspection you put the original back and again remove GPF. understood that changing the flexpipe if it is legal.
There is no wrong or right. You can choose whatever diameter you want.
70mm is a little bit more than stock. 76mm is recommended if you want to modify your whole exhaust to 76mm and tune your engine.
If you want to drive stock you can save yourself the money. You won't have any noticeable improvement.
