what if you put on the original pipe to the cat and then leave the (bigger one)

on from the cat back it might reduce it enough.....?!?!?!??

worst to worst.... fail the test.... fit stockie..... redo test..... drive around for a mnoth with stock on... then refit bigger....

or chat to an exhaust place and see if they can help you ....

Richie,

That maybe true but as far as the EPA are concerned, they tested my Nissan Skyline with my number plates :shake:

INASNT, if yr really worried bout your car failing, find someone with a stock R33 white GTSt and change rego and complience plates over and you'll be fine.

Trust me. I know from experience :)

also, over here in QLD, i know this isnt realated, but we have 2 DOT places and they are so full that its not funny. when u get done, u might have to go to the pits and book a time in to get it checked, theres now a 2month wait to get ya car checked.

so i sugest u do it legal and u wont have to worry. do it illegal and be prepaired to wait.

btw i dont know if them butterfly shutters are illegal but i dont see why they would be.

and they would restrict some power as the flow would not be as good. but this allows you to run a bigger exhaust diamater. so i dunow.

yep got 83 db, with the stock cat back exhaust!

they revved it to nearly 5000rpm, if it went over 90db i was gonna tell them they r only meant to rev it to 3200rpm as stated in the rta regulations. I let em off coz they were real nice guys and idnt cause me any grief.

And you all thought I was nutz when I said that they would rev it out to 5k.

They have their own regulations down there and will rev your car simply coz they can.

dont think they have their own regulations i think they were just revving it that high coz it would have registered like 75 db at 3200rpm. U can always pull the regulations out if it went over 90db at 5000rpm.

      Rusty roof repair

      By Duncan · Posted

      Shit thing to find eh? I guess the big issue is that whatever "fix" you do now, it might slow the rust down but won't fix it. I just wanted to add that in no way is fixing sheet metal in 3 dimensions the place to start with welding....that is a pro only job because its too hard to work out where things should be, let alone doing a clean enough job that it can look OK and still be strong too.  I needed to get a new rear quarter panel on the GTR and it took a pro weeks to get the old one off cleanly, new one on in the right place and looking somewhat like it should have with most of the previous connecting panels in place. Gluing a couple of bits of metal together with a welder in the garage is doable, but that is totally different to doing panel  replacement

      first time swapping rb25det into r34

      By Duncan · Posted

      This seems to be a very popular swap since all the turbo skyline prices went through the roof! I'll let someone more familiar chime in, but I understand that yes you probably want to swap the loom in to swap out the auto TCM stuff. You should not assume everything just plugs in either, you need to check at least the ECU wiring diagram for any differences at the plug at the left headlight and probably the ones near the ECU that join the dash loom too

      first time swapping rb25det into r34

      By dingleberry · Posted

      hows it fellas, my first post here which seems crazy cos half the forums i read are like the same age as me haha. to make a long story short ive got an r34 sedan (rb25de neo auto) which im swapping to a s0/s1? rb25det, r33 big box and nismo gt pro lsd. i have the motor and gearbox all bolted up outside the car, old motor and trans out. i bought the motor with stock ecu and loom, do i switch over to that? or will it be easier to get a r34 manual ecu and keep the loom if thats even possible.  also engine mounts look different, anything else thats different or incompatible? cheers, hope this all makes sense Paddy

      SAUNSW - World Time Attack Challenge - 5 & 6 September

      By Keeper · Posted

      Plan on the day will be to park trackside. Depending on space availability we will try put a small shade tent and a few of the cars on top of the hill inside turn 3, this is an easy to get to parking area with views of Turn 2, Turn 3, Turn 4 and Turn 5 and limited other pieces of the view around the track. IMPORTANT NOTE! One consideration from previous years is from memory the trackside parking sells out before the admission tickets, for that reason I encourage anyone planning on coming to buy tickets for parking now via the official website; https://www.worldtimeattack.com/ The type of parking you are looking for is 2 Day Park & View (Access Around Venue) Vehicle Pass Only Please note this does not include admission to the event itself, remember to grab that also, and kids under 12 get in for free!
