i am gunna have a Ls turbo.. and i was just wonderin how to make it run quite.. what would i need to have on my piping.. i plan to do 12 psi daily.. with 3in piping

 

quiet?

 

i dotn think you can make it run quiet. You dont want to quiet down the spooling, that is the best part.

 

make an airbox, or find an oem one that will work. recirc bov. wg dump into exhaust. quiet exhaust system.


boom. quiet. fast. hella sleeper

 

i dont really care about how loud the turbo spools its just the exhuast.. that loud.. which exhuast sounds almost stock

 

just run a stock type-r exhaust or something

 

that would create to much back pressure.. doin 12lbs on a drag3 kit

 

open downpipe, its not that bad

 

your turbo set up is not going to sound the same as your N/A set up. what kind of exhaust are you going to run? 3in piping and a quiet muffler kind of contradicts itself.

 

NA set up and turbo sounds different, a NA with no cat and straight piping sounds like ****, its loud as hell and high pitched, but same set up on a turbo car, sounds deep, mean, loud but not kill my ears loud

One or the other here...better performance w/ a less restrictive muffler. More sound suppression w/ a more restricted, baffled muffler.

 

you sound like you need a stcok exhaust with a e-cut out maybe on a WOT or rpm based switch

 

get yourslef a greddy sp2, i got it on mine, although NA its real quiet

 

reroute wastegate into downpipe, 2 1/2 piping with a resonator.

 

Ask around at local shops, some do custom 3" exhausts for cheap (friend got 3" for $140 for a GTI).

If you want it super quiet, run a 24" resonator (basicly any preforated-tube type glasspack) and any muffler. 24" with a 3" straight-through Magnaflow muffler is deep, yet quiet. If you want others to hear you a little, just run 2 resonators. The turbo essentially acts as a muffler - the heavy cast-iron housing absorbs sound very well.
