Drop DB of Exhaust

[Lozza150]

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 ....

i can borrow riantos cat back stock system for the day, then take it of a few days later and put my stock 1 back on. Talked to gerald from ice and he said itwould take 15mins to swap em over

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.

So how did it go,did you pass?

[Guest INASNT]

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.

[rs73]

hey, so u manage to find a std exhaust from someone living close to you!

did they test the emission on yours too?

I wonder where can you get a db meter, I wanna do my own check

[Guest INASNT]

yes i borrowed ronin09's stock cat back exhaust.

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.
