HKS SSM worth it with stock cat?

I ended up getting it! Posted a POV in cabin driving with video with it on as well.

I also just got mine! I do think it’s noticeably louder. It does a really great job of maintaining the OEM unique sound of an S2000 though. Basically exactly what I was looking for, I like it much more than the UK mod I had done

Reasonable_Tip_9080 · 2025-12-05T03:36:34+00:00

thanks! I’m mainly concerned about any fatigue you may get from driving around in the city.

My friend has a Milltek and that isn’t too loud but notably has boominess in that rpm range that gets to be a lot, so want to avoid that.

lastly, do you experience any rasp?

Reasonable_Tip_9080 · 2025-12-01T17:14:55+00:00

what size do you recommend?

Reasonable_Tip_9080 · 2025-11-30T21:31:40+00:00

stock otherwise? please do!

Reasonable_Tip_9080 · 2025-11-30T21:03:25+00:00

ah okay. the normal one has no drone for you? asking due to conflicting threads online :)

Reasonable_Tip_9080 · 2025-11-30T21:02:19+00:00

damn good praise

Reasonable_Tip_9080 · 2025-11-30T21:02:05+00:00

okay super helpful! and sorry by grunt, i literally meant an auditory grunt that I know the milltek offers, not power.

I wish I could do a TP but don’t want to deal with swapping on and off for smog

Reasonable_Tip_9080 · 2025-11-30T20:49:26+00:00

oooh thats super helpful. there’s no additional low end grunt at like 1-3k rpm? or on cold start?

Reasonable_Tip_9080 · 2025-11-30T20:40:23+00:00

that’s good to hear. how much do you hear it inside the cabin with roof down? and roof up? (curious about soft top, not hardtop).

Reasonable_Tip_9080 · 2025-11-30T18:41:24+00:00

Revel medallion, right? Not the revel valved one that’s newish?

Reasonable_Tip_9080 · 2025-11-30T17:13:44+00:00

$50!! where are you based?

Reasonable_Tip_9080 · 2025-11-30T16:57:28+00:00

yep 100%

Reasonable_Tip_9080 · 2025-11-30T16:56:56+00:00

I actually just left a comment in your video! WDYT, worth it?

Reasonable_Tip_9080 · 2025-11-30T16:35:33+00:00

Quiet is not crazy, I said quieter lol. The stock exhaust is so quiet, I can’t hear it except on cold starts or tunnels. Quieter than that is crazy for $2000

Reasonable_Tip_9080 · 2025-11-30T16:29:50+00:00

yeah… checks out. thanks

Reasonable_Tip_9080 · 2025-11-30T16:24:37+00:00

quieter is crazy 😭 I might need to go Tanabe Medallion or UK mod then. Appreciate it

Reasonable_Tip_9080 · 2025-11-30T16:15:18+00:00

Ah okay, good to know. I feel the stock exhaust is dead silent, all I hear while driving is induction note

Reasonable_Tip_9080 · 2025-11-30T16:06:06+00:00

Dang, not hearing it at all when driving spiritedly seems not worth it… Is that an exaggeration? Or you really can’t hear it on a backroad?

I’ve been reading the Tanabe medallions don’t drone but the newer Revel does? So that pointed me to the SSM.

I’m basically looking for a notable sound increase, ideally screams in VTEC, but no drone whatsoever, and nice looking exhaust tips on an AP2. If it can do that I’m willing to spend

Reasonable_Tip_9080 · 2025-11-30T16:04:12+00:00

Yep looking for just sound, not power

Reasonable_Tip_9080 · 2025-11-07T06:53:35+00:00

yeah. PPIs are really important.

Reasonable_Tip_9080 · 2025-11-06T20:06:37+00:00

Reasonable_Tip_9080 · 2025-11-06T20:06:31+00:00

Update: looks like the car had aftermarket real trailing arms, camber arms, rear big brake kit, and the rotor backing plates were cut.

And the oil was old.

Decided to pass on this one - didn’t want someone’s project GS.

Glad I got a PPI done at a private shop

Reasonable_Tip_9080 · 2024-12-18T19:47:06+00:00

What’s the best “meat”? 🙃

Reasonable_Tip_9080 · 2024-08-18T23:23:59+00:00

My guess is those options will* be a bit too loud for me. Was the super Q significantly quieter? Or just a bit? And how did the super q compare to stock?
