What can I do to make the turbo spool louder. Taking off the heat shield? Also does venting a BOV to the atmosphere hurt any reliability off the car such as idle problems??? Thanks

 

First of all, do not take off your heatshield. I know It looks like crap but It's not A good idea. You want your turbo hot and your intercooler cool. If it bothers you the speedmonkey heatshield is cheap and looks very cool.
I would'nt recommend a bov either. I'm sure you'll hear plenty about that from others, but in my opinion, It's a worthless part.
Some things you can do is to get rid of those nasty kittens in your up-pipe and downpipe. Also the silencer mod adds A little sound. Trust me, the cats are the key. Your turbo will make so much damn noise at first you'll think there is problem. If you just want the high pitch whine, than just stick with the silencer. If you kill the cats you'll make turbo noise in every gear.

 

i installed a short ram (yes, i know it did nothing for performance) and it made the turbo LOUD..also the bov got louder as well.

i have an uppipe, and a turbo back w/ no cats...the intake is louder than the exhaust. Sounds pretty cool

 

Thanks, I just got my Subie home last night and already removed the silencer and SUBARU emblems from the back. I would love a catless d-pipe however I really want to keep my warranty. Any suggestions on performance parts that wont void the warranty or can be easily removed?
