You would probably run into rasp either way, because of the aftermarket downpipe. Just buy a vibrant ultra quiet resonator and have a shop weld it on. Fair warning though, the spec L will not be loud. In your case it might bring the output similar to what it would have sounded like with the OE...
Ah okay yea a secondary resonator should help reduce/remove the rasp. I didn’t think catted downpipes would add rasp like that. I’ll see if I can post a video
Spec L is a great choice. Unfortunately the engine note catless isn’t great. I’ve yet to hear a good bolt on system, catted or catless.
Now that I added a Vibrant Ultra Quiet resonator to it, the sound is perfect. Deep and smooth with factory like drone throughout the entire RPM range.

I’m still happy running mine with a catless downpipe and frontpipe setup. However I will be getting a second resonator to dial in the note. Report back soon...
The link posted is the 2020 version! I’ve made 2019+ designs :thumbsup: Eric will have a variety of choices, Message JetsVinyl if you want something specific
Haven’t tried JLT but I’m sure it does the job too. I know there are those who make their own kits. I’ve only had experience with mishi and radium so I know they held up just fine. The CCV side doesn’t catch much of anything, but I haven’t tracked it since I installed it either.
For mine I...
The radium requires a little more assembly. But otherwise yes same install. The radium hose is super stiff. I’ve installed three radium ones. Hose is stiff every time lol
Once they are installed they serve the same function.
Mishi is a way simpler install
I had Mishi but got the Radium combo for both PCV and CCV. Whichever one you get does the job. I can’t stress the install enough though lol for another owner we gave up using the hose supplied by Radium due to its stiffness and bought some from an auto parts store...
The stock exhaust does a good job on keeping the tone in check. You will experience slightly more drone and maybe some resonance around 2.5-3k (based on my experience using a PRL catless combo; oddly enough it didn’t sound much louder.
I have my stuff wrapped haven’t had any issues. Back then I...
Did it improve?
When I shift 2 to 3 I actually let the shifter center itself. I don’t recall having that noise issue. What’s your gate spacing set at?
@MuffinMcFluffin the noise you have seems normal, but I wonder if using that shift knob (which is pretty heavy) makes the sound more pronounced. In addition a taller knob height is set to the more force it will see when the lever snaps back.
I have experienced any excessive noise, but I’ve been...
I have a 18 and the 20 has a few cool upgrades. Honda sensing would be awesome for road trips, fortunately we will be buying another car for with all the new safety features. The R doesn’t get driven that much daily to appreciate it.
If I wasn’t so invested in mine, I would consider trading it...
Interesting, I came from Ktuner multistage and stock tune (briefly). Car feels better smoother all throughout with no hesitations. I am using PRL catless DP & FP, Spec L, Mishimoto intercooler & pipes, and PRL stage 1 intake.
Curve looks good! A little odd about the Starting RPM, who knows. The shape similar to my recent custom tune. We also have similar bolt ons. Worlds of difference in how the car feels after. I went in with the mindset of just having optimized reliable power.
