exhaust to noisy

[leech]

Hi,
just wondering if there is any way of making my exhaust quiter than it currently is, i have x-force 4-2-1 headers, sports cat then 2 1/4 back to a magnaflow double wall cannon. i got pulled over by police because it was to noisy and need to know a simple fix to keep performance but less noise. currently it idles at 96 decibels and when at full throttle 111 decibels. Would a second cannon work??

i had the same setup on my b18b, it was 122 dB at peak. i tried a few different pipe sizes, and the only thing that got it under limit was removing the cannon, and putting a proper muffler on, i didnt notice a loss in power. i guess you could try a second cannon though..

silencer

[leech]

cant go with the silencer cause its a double walled cannon :(

This has been covered, but put in a stinking long resonator.

[leech]

already got a resinator, 4got to mention

How long? Put in a longer one.

[Lex_EG93]

shit... go with jims idea. you wont loose any power. did they defect you?

[leech]

nah i didn't get defected, police arnt to bad up here they just want me to look into getting it fixed, was thinking about a longer resonator but not to sure if it will make much difference as i already have a fairly good one, what about a type r muffler? or would that affect perforcance to much?

[Zdster]

How long is 'fairly long'? I have a 22" resonator on mine and it reduced the sound considerablly from the smaller one that I had.

My suggestion would be take it to a competent exhaust shop and ask for their recommendations. You could add a second muffler, but IMHO you would be better and cheaper to add either a longer or even a second resonator.

thanks, the bad thing about alice springs is that there is like one exhaust shop around and he doesnt know exactly what to do to make it quieter, i might go and organise a longer resonator and c how that goes

[Limbo]

or alternatively you could get another reasonator added. They make them in various sizes so that you can have more in different places.

get a stock type R muffler
if it fits nicely and the tip lines up ur cheering
high flow
stock look
and quiet as

but will the performance be affected compared to the cannon?

u dont want to put a 2nd cannon on, this will only increase volume, good rule of thumb would be almost 6dB using basic physics.

options to make it quieter:
put in something with more restriction, longer resonator/ another resonator
change mufflers, something like ITR will do nicely coz its made for higher performance without the hardcore restriction
put in a silencer, most good cannons will come with a silencer, matter of doing/undoing one bolt and u can take it off/put it on.
put on a twin loop muffler
put on a remus axle back muffler

phoah, a 22in muffler...
:eek:

noob q...
will hafing 2 or more or bigger resonator (22') make it lose power?

22" resonator, not a muffler. theres a difference ;)

unlikely but it would probably make it drone more.
the last resonator i had was pretty much straight through with the sides doing the work, but that was a crapy crap one. not sure what my new mugen one looks like inside but it sure does souond quieter ;)

where can i get a ITR muffler from?
