easy ways of making my exhaust less loud

[sik_chode]

I need to get a noise test on my skyline because a police officer told me if i don't they will defect me.

I think it will be too loud.

is there any way of me temperaroily making it less loud?

does a sandwich mesh plate after cat help?

you could get one of those bolt in silencer dics that sit just in the tip... or if you're good enough at the metal work, make one yourself...

other than that, unbolt wherever you can down the system, pack the sucker with steel wool roll then either leave it there to burn off after or take it out after.

hopw that helps man.

i think Silencers are illegal if they are not welded on

does anyone have a silencer disc i can borrow for a day or so?

so the steel wool won't stuff up the system, i just took my place to the local exhaust shop and it was 101db

will those 2 things reduce it to the 90db i need?

i feel i might have to bite the bullet spend a few hours putting the standard catback on again

Never heard that before... :confused:

those 2 things should do the trick fine man, it's only 10 db... aim for a 20db loss and you'll be right

just go to like auto one or super cheap or something and buy one of those cannons with a silencer in it (bout $100) then keep the silencer and either try return the canon or sell the cannon or throw it away

a mates 180 only has one cannon on the back, its ridiculously loud. he had to get a sound test done to clear a defect. we packed steel wool around the silencer and squashed the intake on the silencer. got 91db, dude knocked it back to 89 for the effort.

was quiet as though, sounded like shit.

jam a potatoe in the tip...

seriously though... most mufflers these days should be able to have a silencer/restrictor fitted, and it doesn't need to be welded on, you just need an allan key. Want a more permanent fix? Weld in a/another resonator in the system.

Also, look into a butterfly plate kinda thing, with a cabin control switch. It's like a restrictor in the exhaust which slides closed (semi closed) to deadden noise. Has been done before, not sure who does it though.

Temporary fix for you though is the silencer/restrictor. And if you whine about having less power, well, there is no such thing as a hi-power quiet exhaust. If you want power, it's gonna be loud.

if you still have the stock cat back then bolt it back on for the test. easy.

i have the apexi EVC in my car, improved the noise alot when restricted

Get a steel plate cut it to the the size of your flage plate and drill one 10mm hole in the middle. Insert the "silencer plate" at any flange location and you should pass a noise test no probs.

Any more than one hole and the noise levels will increase at idle and when backing off the throttle.
