why don't you just use an adjustable value in the exhuast,

apexi and hks make one and im sure other tuning company do too

If your unlucky to get done by an Inspection team on the side of the road, they'll do you rough & dry though.

I have a Fujitsubo Legalis R on my rb25

Either 88db or 89db can not remember

I found the quieter HKS and Trust exhausts are rated at 92db, basically the ones with a larger centre muffler and rear

Check out the manufactures web site, most list the db rating

I have a "no name" exhaust that flows really well that I'm about to advertise for sale.

Has dump pipe and all.

Came in at 88/89DBa (Did 4 readings)

Will bolt straight on.

PM me if interested (I probably won't see this thread again, so PM me about it)

The Hks one is not as quiet as the name suggests judging by previous posts ive read

Yeah still loud IMO. I have the HKS Silent Hi-Power. Apparantly it's 93dB, I've been breathalised many times,never had problems with the noise of zorst though.

It's just a smoother tone and the backfire is a nice muffled pop. :D

easy answer PUT THE FACTORY SYSTEM BACK ON

digging up an old thread for that?

The factory system is rather restrictive if you are making a bit of power especially when you can get decent 3-3.5" systems that are street legal.

      Is there a significant price difference between the Evo/gtr/350z brembos vs the F50? Looks amazing.

      I was actually being a tightarse at the time LOL... My OCD is tickling me into running a 2nd 8AN Teflon hose all the way down and removing the 2x OEM hardlines. My other side of my brain is telling me to run 2x hardlines front to back (also acts as a fuel cooler, so win win).

      As I mentioned in an earlier post, I had some trouble with the Silvia's brakes dragging back in 2023. I managed to sort it out then, but the same problem came back to bite me late last year. Just take a look at the picture – I had a feeling the handbrake was acting up again, and I was right. Anyway, I'd been wanting to upgrade to bigger brakes for a while. Not that the Silvia's brakes were bad, but it was more of a "want" than a "need", you know? It was funny, though – at the time, I couldn't find any Evo Brembos, 350Z Brembos, or GTR Brembos for a decent price (of course, tons of them popped up online after I already bought my kit!). I ended up going with an F50 Brembo kit, which came with adapters, brake lines, 330mm rotors, and top hats. The F50 Brembo caliper was used in a few other cars too, like the FPV. I also decided this was the perfect opportunity to ditch the Silvia's ridiculous rear brakes and that awful handbrake (some of you were definitely right about that!). I picked up some R33 calipers and all the necessary bits – rear drums, backing plates, and new hardware to refurbish the calipers. Of course, it wouldn't be a project without a few hiccups. Turns out the brake master cylinder was playing up and basically (to put it simply) keeping the brakes engaged. I had it overhauled, and after some adjustments, everything was working again. The whole process took a while, as you can imagine. To top it off, the front right wheel bearings were shot and needed replacing too. This is a rare occasion where I'm posting an update while it's all still fresh! These pictures were taken just this afternoon.

      I was just going to say that it's good to see you picking up the pace again. Hope the surgery goes well. More downtime just means more time to come up with new ways of digging a deeper rabbithole

      Correct part# for coilpacks for a S2 ER34

      By soviet_merlin · Posted

      How do they compare in size? I have the Yaris coil packs in mine and they work fine. But they are either bigger or sit differently so the engine cover doesn't fit anymore. Not the end of the world but not great either. Do the R35 ones sit flush?
