Hello again. I have been trying to keep up with this ever-changing market. There are plenty of downpipes to choose from (Shark/Tork/Scorpion/RPM Performance/AFE/SXTH). But, which is the most well-rounded? From engineering, construction, hardware, performance, and does it throw codes? Personally, Im looking for a: bolt-on (heat shield retention), well-constructed, high-performance downpipe - with no codes. I am not going to tune any time soon, as i wish to keep my warranty intact. I am clear about the work-around with j-bends. I would prefer to not have to do that, if possible.

Shark: 2019+ Veloster N Performance Downpipe
Extremely well constructed. I have purchased a header from them before, and was not disappointed. Seems like a good choice.
Shark quote: The catted downpipe may trigger a CEL, while the de-catted downpipe definitely will trigger a CEL. You must use a tune to eliminate the CEL.

Tork: Hyundai 2.0 Turbo N Downpipe

Scorpion: Scorpion Hyundai i30N De-cat Downpipe - i30N Performance - Exhausts - Scorpion - Pumaspeed Milltek Ford Performance Tuning Milltek Sport Exhaust Ford Fiesta Focus ST RS Parts Specialist

RPM Performance: Hyundai I30N / Veloster N / Kona N 200cel Sports Cat Downpipe | RPM PERFORMANCE
RPM Performance quote: No EML/CEL.

AFE: https://afepower.com/afe-power-48-37005-hc-twisted-steel-down-pipe-street-series
This is a fine piece, here. Hard to argue with the form of this one. However, beware: https://n-cars.net/forums/threads/veloster-n-aftermarket-exhaust.2345/page-5
AFE quote: 'There is a chance that the downpipe may trigger a CEL. It is normal to get a PO420 or PO430 code with the downpipe. In order to get rid of the code you will need to have the vehicle tuned'.
'Unfortunately, part # 48-37005-HC is no longer an item we manufacture and currently have no replacement'.

SXTH: Veloster N Downpipe
Sublime engineering, precise construction, and almost no chance of a CEL.
SXTH quote: 'Our catted units don’t throw a code 99% of the time. I don’t recall anyone contacting us about that happening to them, although I can’t 100% guarantee that for you'.

Its been over 2 years now since the 1st downpipes started hitting the market, I figured it was a good time to gauge the lead dogs again. The SXTH seems like the obvious choice. I'm happy to be all wrong. Delighted as well, if I actually chose correctly. Thank you.

No matter what DP you go with you will most likely need a J-bend. Even ones with a cat sometimes throw a code. If money was no object I would go with a complete Milltek DP with a cat. If money is tight, I'd go with a Scorpion with no cat. I went with the latter but I had mine Jet-Hot coated. I also had my Ark mid Jet-Hot coated as well. I have that set-up going into the stock PP muffler. Hope this helps?

Best regards,

-Mike

You need to stay with a down-pipe that has a 200 cell catalytic converter and the stud mounting for the OEM heat shields.

There are several other units available then what you’ve listed.


2019+ Veloster N Performance Downpipe

These are reputable dealers, so don’t be afraid to order from them.👍🇺🇸
Thanks Red. Yo Red, u mean this one? https://dynomotive.com.au/product/hyundai-i30n-4-stainless-steel-dump-pipe-with-cat/
Wow, that looks amazing. Soo damn hard lookin'. That's 4" though. That gonna fit? Looks like too much for a stock turbo, no?

Might go with the tork imo since they sell a carb legal one and I’m in CA
Thanks Guy. You gotta do what ya gotta do, no? AFAIK they (Tork) are the only ones who offer a CARB-legal downpipe.

Any good J-bend (the ones with the restrictors inside) will do, no? I'm sure I got one lyin' around here...somewhere.

Yes there are two, a 3” and 4”. The 3” pipe is fine for any application. Both will fit well and retain the OEM heat shielding.👍🇺🇸

I love the beefy look of the 4", but I'm wondering if it will have any negative effects - as opposed to the 3". I would love to get it, but just never seen one that big and don't know exactly what that could mean - downstream. Thanks Red.
