FL5 CTR #0995 CBP
In my opinion, after having deleted just the front, I think deleting both resonators would probably introduce quite a bit of Drone into the cabin without modifying the rear muffler section. If you delete both resonators you will essentially have a straight pipe exhaust anytime your electronic valve is open and not pushing air through the 2 bigger side muffler chambers. The muffler on the center exhaust exit is TINY, it is actually smaller than both of the resonators.
does this apply to the people who have deleted the larger resonator as well where you essentially do not push air thrrough the 2 bigger side muffler chambers?

Ok update time. I have successfully deleted the front resonator. I used some 2.5” stainless piping and a couple of 2.5” Vband clamps so that I can swap the resonator back in anytime I want. For the record the stock piping is NOT2.5” O.D. It’s actually more like 2.35” O.D. Piping but I made the 2.5” work. My car is 100% stock with the the exhaust valve fuse pulled so it is always open.

Here is a sound clip:


The clip was taken with the engine warm after driving the car for something like 4 or 5 miles. Clearly the sound from the exhaust is different than stock. It has this slightly more aggressive tone. Doing this on it’s own does not provide for any of those pops and bangs that the Integra Type S has, that’s clearly as I suspected, all coming from the tune they put on that car. This also does not add any drone in the cabin at all. There is definitely a small volume increase in the cabin from the exhaust but nothing significant. Overall my initial impression is positive, I like it but I’ll be honest, considering the volume change is so small I think the moderate pops and bangs would actually improve the overall sound and “aggressiveness” of the car. I wish there was an easy way to add that to the CTR that didn’t involve having to cough up $1k+ for Hondata and a custom tune.

I failed to get a cold start clip. I thought my phone was recording but when the phone connected to the Honda link app it stopped the recording 🤦🏻‍♂️. I will try to get a cold start later tonight. I will also try to get some driveby’s within the next couple of days.
Thanks for doing that! I think it sounds good enough for my needs. getting older and well neighbors. Now we just need a kit!
Hey @Two Step Performance :D

Have you test driven the type S to be able to compare? I'm curious how much the tune affects the general sound vs just adding cracks & pops (if at all). At the end of the day imo it's tough to improve the natural sound of an I4, you can add character with pops but the pure sound you can never do too much about
+1. The reality is you're hamstrung by a turbocharged inline 4-cylinder motor. Nearly all of the aftermarket exhausts I've heard for this car sound terrible. Spending $1,700+ for maybe a 15% improvement in the exhaust note is not a compelling proposition to me. I'm hopeful one of these manufacturers will figure it out and bring a product to market that enhances the sound of the exhaust in a material way.

Understandable, this mod is only going to be for those who are looking for the absolute MILDEST sound upgrade. IMO this is the bare minimum that this car should have sounded like from factory and the fact that we have to go through this hassle just to improve this one (important) aspect of an otherwise fantastic car is a huge fail on Honda's part. I have a really hard time believing the standing narrative that Honda did this due to noise standards around the world. There is obsoletely NO WAY that this car would fail any noise standards anywhere in the world with just the front resonator eliminated.
Hahaha! Apparently the stock exhaust on the Elantra N is too loud in California!🤣 So I guess if we wanna point the finger for Honda’s overly conservative exhaust note on the CTR…it might be our own country’s fault, which actually would not surprise me at all. 🤣🤣🤣

There are plenty of 4-cylinder engines in cars that sound good, so I don't buy the "hamstrung" argument. It's in the implementation. The problem is that most manufacturers focus more on creating and piping fake engine noise into the cabin to counter the quiet, stock exhaust that's more noise and emissions compliant. If they tuned the exhaust more there would be no need for fake engine noise, and the whole car would sound better (AMG CLA 45 as one example). I do think many aftermarket exhausts are a bit much, but that's how they feel they need to stand out to the buyer. I think the R1 Titan is the nicest sounding exhaust for the FL5, but at $6k, it's not something everyone is jumping on.

Have you ever heard or found clips of the R1 Titan? I love hearing high end premium exhuasts like GT Haus and akrapovic, they really transform the exhuasts on cars

That’s the funny thing and points to the possibility that Honda (Japan) doesn’t know or understand all the restrictions in different countries AND/OR didn’t want to deal with it and simply took an all-encompassing conservative approach. I can very very easily see that being the case. What manufacturer would want to design different exhausts for different countries on one car model built on ONE singular production line? That’d be a nightmare. I mean, shit, look at the US and clearly there’s regulatory inconsistencies just between states (and probably even counties and municipalities). Now imagine what it must be like globally. There’s a ton to consider before simply saying “Honda dropped the ball.” (Steps off soapbox) lol

Europe has very restrictive noise laws, so I would say they were the culprits not the US.

BUT because of the CA case with the Elantra N, the updated 2024 EN will have a less aggressive tone worldwide

I'd argue that Honda definitely dropped the ball. The CTR is supposed to be a flagship high performance car for the brand and with that comes the performance & style (which Honda Nailed) and sound/Emotion which the car severely lacks in OEM spec. We can sit here an try to blame whatever region of the world we want for restrictive sound rules etc but none of that matters because Honda decided on their own to make their Flagship performance car sound like a vacuum cleaner when they could have easily added a bit more sound/character befitting of the car while still begin well within the wide ranging noise restrictions throughout the world. There are DOZENS of cars from other Makes which are sold in all the same different regions of the world and yet still have significantly "louder" exhaust notes. In Europe you have any number of current model year performance version of a BMW, Benz, Audi, VW, etc with significantly louder OEM exhausts. From Asia just go listen to a Stock GR Supra or Corolla, Subaru WRX etc. Don't get me wrong I LOVE my FL5 but it is ok to admit that the car's biggest fault from the factory at least in my opinion, is the underwhelming exhaust note. Judging by the interest that every single exhaust related thread on here generates, I'd guess most owners probably would agree with that statement. I'd bet if the FL5 had received the same Exhaust treatment the Integra Type S is getting, these conversations wouldn't be happening.

I 100% get what you’re saying and I wish the exhaust was as great as the rest of the car too, but this is a somewhat “unique” problem for a non-bespoke/ non-$$$ car. Many cars, as you site, are also built in the regions where they are sold. The ITS is a perfect example of this and is why its exhaust is so much better. The FL5 is built in 1 single plant in Japan. The logistics are far and away more complicated and not really comparable to other production cars in the FL5’s class/ performance/ price range. To find a true comparison you’d have to site another global performance car, of similar production numbers, that is also only built in one place. Like I said, this is a “unique” problem.🙂 I don’t think Honda dropped the ball ; More like they had to settle for a field goal on 4th down vs score touchdown.

I hope Honda provides an update to simply be able to toggle the fake noise off, just like the rev matching. Surely that’d be a simple programming thing.
