How To Make A Dump Quiet? - ZED_not_zee - 04-05-2007
ok so Ive been working on this boosted civic... we have an external dump off the waste gate... it's so retardedly loud... and takes awy from it's sleeper like tendancys... Ie a rust bucket with a "farmers feed citys" sticker....
has any one heard of puting a fat resonator on a dump?.. it's relativly small tubing... so I am wondering if I put like a 3" resonator on it if it will quiet it without restricting it?
no any one who has done it? I don't really want to plum an electric flaper to re-circ the dump into the main exhast and open to atmosphere in a serious situation..

who cares about how loud it is , it only opens when ur at full boost, by then everyone already knows you have a turbo by the sound of spool. if anything the but it back into the exhast or just pull the piping all the way to the back of the car. there is no point in getting fancy with it.
i have a open dump pipe on my car and i like it, i love when people on the side of the road jump when it opens.
if your going for ultimate performance recirculate the dumpand get a 2.5" cutout.

Just dump it into the exhaust and pipe in a bypass for serious off-road performance... hell, if you have an exhaust on the car, you're losing the performance there, not from where you dump the wastegate.

ok all valid points... thanks
but for just for clarity not offence.
my question is "would it make it quieter"? not "should I do it"?
