The detail you put into every mod is insane. You're a God-send for the 2 tuning platforms you've been a HUGE part of.

[@VancityAudi]

Thank you VERY much!!!

[@toddn.3123]

I had custom test pipes and custom catted down pipes installed in my car with the Magnaflow 11385 x pipe on the down pipes post cat, stock center muffler removed and rear stock mufflers in place. OMG was it loud and raspy very little throttle, it just sounded so cheap. Then I added the Vibrant Ultras where the the stock mid muffler used to be and just like you it was quiet when daily driving, but nice and lets say "noticeable" when I got on it. I do have a lower tone then your setup, but still no drone. One thing I will warn you is that the Vibrant Resonators are specifically made for applications in the mid to rear of the car (it actually on the box). Adding it in the front is going to cause them to fail by overheat as our systems run hot, there was a post about his on Audizine. I would suggest you contact Vibrant just to make sure you are ok and don't need to take any action. I live south of you in Washington so I know the our PNW area is not known for getting super hot, but last thing you want to do is blow out a new set of resonators and wonder what happened. If you are interested you can read and hear some of sound clips of how it all played out on my blog - www.mys4.org/

the vibrant ultra quiets are AMAZING we put some on a truly straight pipe 09 charger RT and it made it sound soooo great

[@Corbots80]

Definitely not too loud. sounds pretty good, just a bit too raspy still. But thats hard to get rid of with test pipes. Gutting the cats is a better option if you want a really nice sounding exhaust

[@birchfingers5706]

Subscribed. My cats have been hanging on for awhile now. Been stage 1 IE since 85k. Now at 140k. Have a set of stock cats with 70k on them bought off AZ. Plans were to hollow them. But kicking around relocation and vibrant. Thanks.

[@VancityAudi]

The amount of heat you generate on a Stage 1 tune is significantly less than what you see Stage 2, especially on a dual pulley setup. I had no doubt in my mind my cats were completely fine on Stage 1. I personally would keep the cats in if you are sticking with the Stage 1 tune from IE. If you really are concerned you could visually inspect them before spending on the money on relocating them.

[@davidmusiyenko4158]

Finally !!! I went with JHM test pipes and JHM catted high flow down pipes :D

[@Bytrl]

You realize you paid like $2000 to replace the cats.. right?

[@davidmusiyenko4158]

@@Bytrl it was like 1600$. 1 reason-Lots of guys who gutted their stock cats had the welds blown off when they were increasing their power past 93, and ended up buying nice new test pipes either way. Reason 2. Jhm test pipes are a very nice build quality, I’ve done countless research and they are the best on the market (600$) Reason 3. I went with the high flow catted non res downpipes (1,000$) because it’s not some janky setup with some weird ass muffler you gotta cut in an weld into your exhaust. I want my car to sound good but not to be blowing out clouds of smoke and have my car smell like crap. Also the Jhm system is actually very nice and fits perfectly all together. Car sounds incredibly good, I get my amazing pops and crackles, and not have to deal with the insanely loud rasp/drone. I didn’t just replace my cats, I replaced mid downpipe section too.

[@pklifter]

Update, I ended up getting these cts test pipes (downpipes are too expensive for shipping to Australia) and had a muffler shop fit them locally, took them about 6 hours which includes fixing a snapped manifold bolt. They also fabricated the rest of the exhaust, now I'm frantically googling "resonatnor" "drone" and "rasp". Fixed in Part B of my exhaust work I guess hahahahah. However the shop did say they had no issues fitting these CTS Turbo Test Pipes on my B8 S4 (right hand drive car).

@@VancityAudi pretty sure the outlets are smaller pipes in diameter then your down pipes. So you got a lot of flow then necks down at the end. I could be wrong but almost certain that’s how it is

Hey Adam I just had my CTS test pipes installed and am just a bit confused did you have to tune your car in order to keep that engine light off or did the spacers just just keep it off for you because my light is on but my car is currently not tuned?

[@VancityAudi]

Yes, the spacers we used are to prevent the CEL from coming on.

[@AxialMotorsport]

You’re initial reaction was just like mine! 😂 I’m driving around without resonators and it’s horrible right now. I don’t have any drone cruising under 2600rpm. The real bad drone/rasp is under load 2800rpm plus.

Great vid. Did you do a before and after 0-60 and 1/4 mile run? Should have seen a gain. This is my next step with my ecs valved exhaust. Thanks for sharing.

[@VancityAudi]

There was no gain from running test pipes. I actually ran my quickest ET and the exact same trap speed with the cats still installed VS having the test pipes installed. I'm honestly baffled as to why so many people think they make more power with test pipes. Possibly from all the false advertising exhaust companies put out there, haha.

[@dtbrown1978]

@@VancityAudi thanks for reply. Just looking from the restrictions of the cats to the test pipes I'd think there would be a gain but makes sense no gain as the stock exhaust diameter pipes is still on and that wasn't changed. So overall airflow capabilities hasn't changed from using the stock exhaust. Maybe a small gain would be seen if have a full aftermarket downpipe back 2.5" exhaust where the bottle neck would be the stock cats off the headers. I just ask as I have ecs exhaust and wondering if worth the investment. I know if go to stage 2 probably will burn the cats so probably have to do it anyways.

[@VancityAudi]

I personally don't think it is worth it at all if you're looking for more power. Some of the fastest B8 S4's in the world use the stock rear portion of the exhaust.

@@VancityAudi appreciate the feedback. Good perspective and I agree. Saw your heat exchanger review and definitely a must once I do stage 2 with pully install.

[@VancityAudi]

@@dtbrown1978 I'd recommend doing the heat exchanger upgrade as your first hardware upgrade, not once you're Stage 2.

​@jonpolo2900 in a State that tests emissions? Don't modify your car enough that you are forced to modify your exhaust system.
