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

      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.

      There's not a great deal to report here .... except ...... FOR .... LSD!!!  I bought a Quaife LSD from the UK and shipped it here .... Wish I'd just bought locally cause the shipping and duty was $700! But there were so many diffs used in the E90s I just wanted to be absolutely certain I was getting the right one so I spoke with a supplier in the UK who builds race cars and they have heaps of experience with the E90s.  I pulled the diff out which was seriously awesome - I've never done anything like that before, I must have watched 1000 videos on YT about it as well as consulting the Bentley manual. It was super easy in the end. The diff was delivered to the awesome folks at Hornsby Diffs and will be back in a few weeks. I also replaced the diff bushings with some Nolathane ones.  Really looking forward to getting it back and getting back to the track or even the skidpan.

      yeah... the 13kg/mm springs weren't always in there, I had 10kg/mm but doing a few SMSP commanded heavier front springs. It's so good now going into T1 and T2, just need more seat time and real tyres.

      Yes, well. Mine are less than half that. ARBs are not set to "dumb" either.

      I would hope. But, we all know even the best companies have an issue sporadically.
