Exhaust to loud!!!

[|PRESA|]

I was pulled over tonight and luckily that I'm a good bloke.. I was nice to the coppa and he was nice back!!

Pulled my bonnet up and he saw a number of things he could d!ck me on.. but i played stupid and got off on most of it, although he warned me about my exhaust being to loud, and me being on that 12month probation thing I dont want to attract more cops..

So what can I do about shooshing the exhaust but without loosing power?

At the moment I have a 3" dump/front pipe bolted onto a super hi-flow cat, bolted onto the standard 3" cat-back with a 3" muffler 4"(tip).

I was thinking about putting one of those silencer plate thingy's in the muffler tip, but I don't know if that ill stuff the flow of my zorst and loose power.. anyone?

Fit a second muffler after the cat if you want it reaaal quiet.

Fit a resonator after the cat if you want it quieter (that's what I did..).. it's still loud.

Then if it's too loud get a muffler that's known to be quiet. Mine's too loud with the resonator installed and the cannon, so I'm going to try to replace it with a super dragger cannon (known to be quiet) or a kakimoto (nice sound and not a cannon).

Good luck.

you're lucky. I got defected tonight in sydney (about 30 friggin cops setting up defect stations all through inner syd). I own fairly stock skyline, hks pod, strut and kakimoto exhaust about only mods. They got me on pod filter & a busted high beam (which must have happened in the last 2 days as i checked it on wed!!!!) sigh.

I was nice too but they were a bunch of knobs!!

ps i'm aussie too!!!!

u will lose power if you put a plate in the exhaust but it will be quiet, dont do it!

easiest thing to do would be to fit a good muffler, twin exit ones are generally good for keeping things quiet dont use a canon...

how do they test the noise? do they have some sort of meter on the spot or are the just guessing it's to loud?

[shif_tea]

they will have a dB meter which will measure how loud it is

get one of those butterfly things for ur exhaust from nengun, like 200 bucks delivered then u can open and close it from the cabin to reduce noise, pretty easy to install too mate has 1 on his rexy, goes almost silent, when its left open a tiny bit

Wouldn't that be bad? Is it like sticking a potato in the end of your exhaust?

It'll quiten it down but does it still let the gases flow through?

Plus if you actually see cops and who has the time to flick a switch, I'm just thinking of excuses to get out of sh!t..

it will be a big blockage in the exhaust it wouldnt run too nicely, apart from the silence..

useful for epa inspections etc though.

[2BNVS]

yer its mainly used for epa tests but if he has to quickly close it he never closes it fully and the actual butterfly plate thing has little holes in it already to help a bit of gas flow through even when its fully closed...

Would you say even with the butterfly flap fully open that it would still be very restrictive?

[2BNVS]

its not restrictive at all when its fully open.
