Update: installed the Section 1 last weekend and drove it yesterday. Fitment was spot on. it was easier for me to section 1 and 2 and put it together outside of the care. i then used a jack, slid the section 1 in, fit section 2 to the muffler, then put the mid-brace on, and then torqued both ends.

Breakin: for those that don't know, from what i understand there is a break-in cycle for new cats, which is very simple. turn on and idle for 5 minutes, then rev to 2500 RPM for 2 minutes. turn off and cool down and that's it.

First drive: i don't know if the tone will change as i drive it more but after driving it, i'm a bit surprised. considering HJS claims upwards of 93-95% airflow, i expected the car to sound louder than my Euro Section 1. the result is the car sounds very timid. fwiw, i have Euro Headers, SS merged Section 2, SS Race Muffler. the drone is down to a minimum and the rasp is subtle but there...which i actually like.

i don't have any video yet but will put something together when i can. overall i'm pretty satisfied. i have a pretty good flowing system with a sound that isn't as loud as thought it would be.

Great to see this DIY. As I am actually thinking about doing the same, would you share you impressions after some time? Was it worth it? What about smell? Power wise, do you feel any difference?

thank you for your thoughts

For $1,000 I got the Active Autowerke section 1, with 100 cell high flow cats. I don't really have any complaints. Smells way less... power is there but at times the engine feels more "jerky" if that makes sense. Happens occasionally if I get on throttle too quickly and never did when I had no cats. Maybe my driving. Sound is a little less too, sad face. But for my life, as my daily, a little less sound has been a good thing.

EDIT: If I could go back I would've bought fattycharged's SS With aftermarket cats tbh.

Did you reset adaptations?

Did you reset adaptations?

I brought the part to a specialist and had them install it, I don't know for sure if they reset adaptations, this is the first I've heard of it.

Is it doing something like this?

i feel it's completely worth it.
i was running catless and then put this on so performance wise, i feel like i didn't lost much/any from going back to cats.
considering these are HJS cats, they still have that performance aspect while doing their job with the smell/emissions.
absolutely zero smell.

for comparison, this YT is of my Euro Headers, HJS-Catted Section 1, SS Res Sec2, and SS Sport Muffler.

To ensure that they have been reset, it is best to use an OBD tool such as INPA or the ECUWorx MSS5X tool.

Great Thread, as I get older the smell is starting to annoy me too. Im guessing im going to save up and wait for a black friday sale and just get the SS Section 2 with cats for my V1 headers.

MarcoPolo in the first video you say you have

Euro Headers, SS merged Section 2, SS Race Muffler

and in the last comment you say

Euro Headers, HJS-Catted Section 1, SS Res Sec2, and SS Sport Muffler.

. I'm curious if you switched from Race to Sport? I currently have Catless headers, stock section 1, SS merged Section 2, and SS Race Muffler and I'm looking to quiet it down a little and avoid the smell. First video you posted sounds great but I'm wondering if I should switch to sport as well. I'm more concerned with the sound and the slight drone/rasp at 3k especially when the engine is cold, wondering if I should go HJS cat route or try out the RE rasp pipes both seem to be around 1k give or take.

Yes I have both sport and race. I'm at a crossroads because for me race is too loud where a sport is too quiet so I keep on switching back and forth to see which is the one that I want.
I can tell you for sure that the sport is pretty quiet but I also got an airbox so all I hear is the airbox sound.
