Does anyone know how loud a straight pipe 80mm setup (no cat or muffler) would be on a RB20DET? I do have a VG30 turbo since that might make things slightly louder (possibly negligible though). We don't have inspection where I live so it's not a big deal to run it like this... unless the dB level is over say 95dB.

I just bought the Kei Office XT-alpha suspension for my S13 and was planning on running something temp. until I can buy the JIC 505S Ti setup... unless I actually really like the straight pipe setup and it's not stupid loud.

would be 80-90db by 3500rpm

Its a bout as loud as a 4cyl with no exhaust at all. I get headaches from driving at 100km/hr, with or without stereo on, but u get use to it, i am putting sounddeadener inside & out to quiten it down. I am half deaf so it doesn't bother me as much as it would other people.

Cecam: I don't think it sounds bad, just a bit different, alot rawer harsher sound

      I am yet to see anyone ever regret a quaife or helical. ...other than drifting/skidpan duties. I kind of want to upgrade my factory helical with a Quaife (but really it's not ultimately that different, and is a MASSIVE UNDERTAKING), that's how good the hype is about them, that I want to try them 'just to see'

      D2 and Ksport are essentially the same thing and basically just generic Taiwanese manufacture. Better than ChinaBay crap, but... not top shelf. Öhlins have got to be some of the best dampers around, so likely to be a good option. It's going to get to the point though where I suggest you buy from Oz. We have at least 2x excellent options here. If I were you though, I'd be talking to KW about doing something for the R33. There's bugger all difference between that and the 32. In GTR land, anyway.

      KW only offers a set for the R32 GTR. Popular options are D2 racing, Ksport or Öhlins. I have a D2 Racing coilover set, though I don't know for sure which one.

      Well, the good news is you have more than one very good option for new coilovers in and around your country. Worth the drive over to KW to talk about GTR stuff.

      Fair enough, I am in no way a tire expert so I'm not familiar with all the terms and conditions. I'll definitely note down the AD09 to potentially try in the future. Rain is not too big of a concern for now as I will probably only drive in the rain when I have to. And considering I still lack experience driving the GTR I'd more than likely take it easy too. I have coilovers in the car but as I barely got to drive so far I never bothered to even check if they are adjustable haha. The suspension is almost entirely old and worn as well so I suppose when I eventually fix that in the future that would make a huge difference.
