Default TURBO LOUD-ness...
would dumping the downpipe(s) do anything as far as loudening the turbo at idle, and at cruising\?

lol at loudening!

I think it would. My friends turbo camaro seems to have more turbine noise when the cut out is open...and his cut out is ~4 feet away from the turbo on the down pipe.

Mine are really loud with dumped downpipes, I've never had exhaust hooked up to tell the difference

The first video in my signature is with open down pipes and incons... It's signifigantly quiter with the exhaust, but when I hit the electric cutout, sounds just like the video.

This is a soundclip of my Incons through an open y-pipe with a 236/236 112LSA cam.

When I put on the factory Firehawk DD exhaust it sounds so freekin' quiet. Complete sleeper.

Does the open downpipe sound good when driving? I know sometime without mufflers you get crackles and pops...

on the highway she purrs nicely, the turbo spool becomes louder than the engine, so you get to play with 18 wheelers and they give this look when they hear the spool.

Regular street driving sucks. Lots of sounds you don't normally hear and can make you crazy. Gonna have a cutout put on right there where it dumps now, and have the rest of the catback connected.

Don't know never tried it. I'm tempted to though. It sounds like a V-8 powered Honda Accord right now with my SLP dual/dual on.

I might swap catbacks to the SLP loudmouth to get some sound back into it. Just way too much of a sleeper... I like to hear the cam... and the turbos have muffled it down to nothing.

Get a 2 step and spooling those turbos with a 6 speed will be much easier... at least from the line.
