Post VRSF or AA DP?

Hi, I'm running bm3 stage 1 93 octane right now, and I am thinking of getting a catted DP and going stage 2.

The VRSF high flow is 500$ right now and the one from AA is going for 1400$.

What's the difference between the 2 and is it worth paying 1k more for the AA dp?

thanks.

Active Autowerke uses GESI cats that are EPA approved.

GESI cats do not throw a check engine light even if the car is in stock. The cheaper brands will.

Please note, that even if you have a tune that hides the check engine light, your car will fail emission testing if you are not using approved cats.

Lol - drive a car that was close to $50k when new - but hesitant to spend $1400 on a DP - so now you have to try to get past emissions somehow. Sell it and buy a Kia.

Btw what is the difference between ECE and EU6 compliant DP?

I have seen euro cats (ECE or EU6) throw codes

if you want a 100% guarantee, get GESI or HJS cats

I don't want to spend close to 2k more for a catted dp i.e. with worse performance. If I had that type of money I would of gotten a porsche.

Also I like kias. Have a good day.

Your car, your money, your choice.

Performance is the same with high flow catted and catless, especially on the stock turbo.

Catless: cheap, fuel smell, emission problems

catted: no check engine light, deeper mid range tone and no fuel smell

$1400 is NOT close to 2k it is closer to 1k
And 240 + 2k still isn't Porsche money

also, $1400 is retail and not necessarily the best price you can get it for

I've said it before - 99% of the people on here who think catless makes dramatically more power, cannot drive well enough to use the negligible gains. Even BMW race cars have hi flow cats, so really the whole catless thing is cost and sound.

I have nothing against Kia BTW - they're just not exciting to drive.

Cool. I think 1k is worth asking about before spending. And I got my answer . There's no big diff between the two DPs.

Sure there is a difference. Build quality is one of them and the quality of the cat the next.
You can get lucky, but others have not.

1400 is closer to 2000 than 500.

In the end, it doesn’t matter and people have better things to spend money on.

I'm currently debating on getting tuned and the only thing holding me back from stage 2 is the potential cost of upgrading my clutch. That being said, I would never get a vrsf. I've seen pictures of cats imploding. My choices would be AA, Wagner or CG.

That being said, I'm leaning towards AA. IDC about the gains from catless. I just want to have fun and don't want to deal with the hassle of not potentially paying inspection when the time comes.

Lightbulb VRSF DownPipes with Warranty

The title might be confusing but I have extended bumper to bumper warranty on my car. I called my dealer about going full stage 2 which includes (VRSF DP, Catch CAN, CAI, XHP stage 3 tune, MG Flasher Stage 2 tune). He said he would ask the shop foreman what would be voided in my warranty etc. For now, I am just gonna start with stage 1 MG Flasher with CAI to play the safer option.
Has anyone ran into similar issues?

if anything can cause warranty issues, it's the tuner. If you are worried about your warranty, you should wait before getting an MG flasher.

DP, catch can, intake will not cause any warranty issues as they do not add any stress on other car components.

With that being said, your warranty is no affected even with a tuner as long as you are not asking them to fix a repair caused by your tuner.
