I have 1k miles on my 19....I will be following your progress

[@GridZilla]

Welcome aboard!

[@7yellowcard7]

Great vid! I thought the catless would have been a lot higher BHP than you found! How does it sound with the sports cat and remus? Do you think you'll get the silencer for the remus with the sports cat or is not too loud?

[@GridZilla]

The Remus exhaust makes all the difference in the world. Perfect amount of loudness with the baffle on the exhaust all the way open. Still have the flexibility to go quieter by closing the baffle. Too loud with the Catless. Perfect with the High Flow. Thanks for watching!

[@jcp227]

Well I guess I'm not getting your catted DP now. Haha Thanks for sharing and nice job.

[@jcp227]

Hey Mike, I just ordered my FP and DP from RV6. They are having a FP presale so I went for it. Is there anything you would recommend of having done while all the stuff is out of the car? I was most likely do a turbo blanket but was trying to think of anything else. I don't plan of pulling all the stuff back out until I decide to sell. Also, did the sound change dramatically when you changed the catted DP and FP?

[@GridZilla]

jim payne it is a dramatic sound difference with the down pipe change catted or not. You'll love it. If you haven't already I would recommend getting an intake and a tune. Intake needs to be removed anyways so might as well put in a new one and definitely a turbo blanket. The ptp fits nicely under the stock heat shield which I wanted to retain. The tune you'll need to keep the check engine light gremlin from showing up.

[@jcp227]

@@GridZilla Yup I'm running KTuner Stage 1 already. I started pulling this apart and it wasn't super fun to be honest. I think I'm going to throw on an intake while I'm at it. I don't want to have to do this too many more times. Thanks for the feedback.

[@GridZilla]

jim payne I don't blame you lol no problem

[@angelogouvis1885]

Mike - great video, and congrats on the content, production quality, etc. Very top notch. One question: what was the WTQ (wheel torque) difference between the two? It may have been in the video, but it went by pretty fast. Thanks, and keep up the great work.

[@GridZilla]

Angelo Gouvis torque actually dropped a couple lbs but I think that can be easily tuned for a bigger gain. I hesitated using total numbers because the canned tune is too basic to illustrate what this set up can really do

[@GridZilla]

I'll be doing a full custom tune coming up in early May. Then we'll really see what this set up can do. Stay tuned!

[@XRoseGold914]

Hey I have a Remus exhaust , stock front pipe , stock down pipe How’s the drone with the dp install ? And how’s the catted dp from rv6 ? Is it any good

[@GridZilla]

Definitely some drone and rasp with a cat less dp. Little to no done with the RV6 catted dp. RV6 makes the highest quality stuff in general for the FK8

[@weduhpeople8504]

Btw happy belated birthday brother! I had just put on the Tomei full ti Type D and been running the RV6 catless downpipe and front pipe on the stock exhaust which sounded deep w no drone. The Tomei, holy moly it’s ridiculously loud and with the included silencer baffles put into the tips it’s still loud. I ordered the RV6 high flow catted downpipe. Hopefully this quiets it down a bit more. It’s my daily so rn it’s a 🚓 🧲 😂

[@GridZilla]

Ronald Batalla Thank you! I was really curious about the Tomei Exhaust. Sounds good for sure. The high flow catted RV6 will definitely help

[@nunofranco4232]

Hey, what was hp gains over the factory down pipe and does the high flow cat set off the check engine light? Great video!

[@GridZilla]

Nuno Franco is about an 11hp gain over factory without tune. The check eine light may not come on with the high flow but I recommend using a tuner that turns that will keep the cat from throwing a cel. Thanks for watching!

[@thientran4426]

After watching this, I decided purchased catted. Thank your video.

Thien Tran you'll be happy you did 👍🏼

[@tuetran1238]

Need a good tuner around the Bay Area. Who’s your tuner if you don’t mind me asking. I have the PRL IC, charge pipes, PRL intake. Will be getting a catted DP and FP soon. I’ve seen you around town a couple times too. I know the spot you go to make your videos by the water and tracks. It’s a nice spot. Thanks

[@Strikeitbigtime]

Nice to see the differences Michael , I was thinking , keep my standard exhaust and just change the downpipe , or do you recommend changing the lot ? I just don't want it to loud inside the cabin ,Thanks 👍

[@GridZilla]

pal wri that's exactly why I got the Remus exhaust. Loud when I want. Quiet when I want but you can definitely run the downpipe with the stock exhaust. It will for sure bring in a nice growl without being loud

[@bxcloud104]

Thanks for the video, can you post a more detail dyno image of catted vs no-catted? Peak power is nice, but doesn't tell the full story.

[@GridZilla]

bxcloud there's an image of the dyno showing hp and torque but because this was on a base tune and the rpm module they use for their dyno at Tech3 is outdated, the torque curve looks distorted. That's why I didn't really cite the torque numbers. I'll be getting the car custom tuned early May at a different Shop. Will get some solid numbers and graph for you there. Thanks for watching!

[@MrErick-zg9gj]

With strict emissions and as a California resident, I assume catted is the way to go

[@GridZilla]

Mr. FredRice for sure

[@angelogouvis1885]

Bad news, Mr. FriedRice, non-OEM cat won't fly with the Cali Smog Nazis (a.k.a. CARB). Even if you meet tailpipe emissions, no joke. You could still be fined, if you get caught. CARB is one of the things I don't really enjoy about living in Cali. However, I plan on running a catted RV6 on my CTR (soon) because: (1) Avoid the nasty un-catted exhaust smells, (2) it's the right thing to do for the environment, and still make good power, and (3) sound is a little less raspy than the uncatted.

Angelo Gouvis the risk you take living in Cali

[@forrestbashaw1455]

@@forrestbashaw1455 : I haven't read the CA vehicle code lately, but from what I understand, any modifications to the emissions control system is strictly verboten. Just to clarify, OEM means Original Equipment Manufacturer (in this case Honda), who only makes the one type of catted downpipe (which came with your vehicle).

Aaron Ticzon custom tune is coming. I'm guessing around 350hp because of garbage 91 octane gas. All the numbers in the range you are talking about are on 93 octane. Getting it done early may.

[@r3kop]

Have you had any issues with the catted rv6 as to date? Any updates?

[@GridZilla]

Zero issues! Love the RV6 Catted Downpipe. Definitely one of the better bang for buck upgrades. I would however say that for my tastes I love the sound but if I had to live with the added volume 100% of the time I might find it difficult but the Downpipe paired with my Remus exhaust is a match made in heaven for me.

[@iPhone_tek]

Hey did you have to retune for high flow cat , or does it not matter on the tune ? I am running hondata but I don’t see a mapping for high flow cat with intercooler and also intake

[@GridZilla]

GLOgangNoSquad the base Hondata map with Downpipe is fine but I always recommend a custom tune

[@mr.tuckers2848]

Another fine review!! Thanks for sharing the experience!! I'm glad you decided to go back to the 200 catted downpipe. From what I've learned so far, the catless downpipe introduces exhaust fumes and is noticeable into the cabin. Did you notice this inside your car? For only a 2HP gain, I don't think it's worth enduring such smells (if any) and it's more about choosing the right sound and most importantly HP & TQ gains. Glad you found the right combination that pairs well with your ride! RV6 catted looks like a win!

[@GridZilla]

Mr. Tuckers I probably didn’t have it on long enough to notice a big difference in smell with the catless. Either way not worth the 2 hp difference for sure. Love RV6 products. They definitely make quality stuff!

[@vallasjo8003]

either way its nice bro!

@@7yellowcard7 I am using the off the shelf map but all it really does is make sure the Check engine light doesn't come on.

After listening to exhaust comparisons between catted vs catless, we decided to go with a catted DP with a high flow cat in our turbo cobalt, plus the benefit is there is no highway drone, and the car is quiet when we want it to be...
