Exhaust To Loud?

[Captain Natro]

the only way to stop drone is a smaller diameter system with more mufflers/resonators in it.

mines only 2.5" and already has 2 mufflers/resonators in it and an oval on the end

[mad082]

is your cat converter still intact?

and how big is the oval muffler? my commodore only has 1 oval muffler in it (2.5" system) and it isn't very loud at all. it's a decent sized muffler though. also, what sort of resonator does it use? is it the oval type? it may be that they fitted it the wrong way. when i got one put on the pulsar it had a right and wrong way. fitted the wrong way it wouldn't do much to quieten things down.

im not entirely too sure about the details of the system, i got it second hand off martin on these forums

all ive done is change the end muffler to a mild steel oval one

cat was still in good condition last time the car was checked .. but perhaps this will be a good excuse to go get a hi flow one on

the drone/loudness is only till about 2500 rpm, and the car is much louder some days, near quiet and nice others - perfect on those few days.

perhaps ill get a hi flow on and get kermit to check out the rest of the system at the same time though

*edit* ive been seriously considering swapping back to the stocker, but it does feel a fair bit more responsive this way and i quite like it

Slight side topic. Does the cleanliness or age of an exhaust determine its sound output also? I imagine it wouldnt be a huge difference but I was wondering if it would change over time? as the small holes in the muffler may get blocked up etc.

PS my problem got solved just got another muffler works a treat all nice and legal

yes the age of an exhaust will alter the sound. the piping gets a layer of carbon on it which will make it quieter, but at the same time the mufflers will lose their ability to absorb sound.

get a piece of steel plate, cut do dimensions of flange, drill a couple of holes in it, fit between exahust flanges.

btw open piped n/a skylines sound like teh gay

Get a resonator installed, it's quite cheap and you can ask to get it removed afterwards xD
