Fix for high Idle? Options

[mark95turbo]

Well as you all know when the stock intake is modified (lower combs removed) it idles high on cold starts. Well this wasnt really that big of a deal when it wasnt so cold out, but now that its a bit colder its really annoying. On the really cold mornings it idles up at 3K rpm's. The fact that I work at 6am every morning doesnt help how annoying it is. I'm sure I wake all of my neighbors up daily with the combo of a 3" turbo back exhaust and a 3k idle. So......... my questions are, on how to fix this. Does the GM maf fix this problem? I sold the second gen so now im ready to start pumping some more cash into this beast. I wasnt planning on starting there, but if its gonna help I may just have to. Also, I know this has probably been asked a thousand times, but is there a quieter solution to a fairly free flowing exhaust? I can't stand the sound of this thing. I'm hadly on it enough to spool up the turbos which is really the only time a 40-bangar sounds good IMHO, but its still horribly loud. Any suggestions on fairly quiet mufflers? Thanks guys!

Not sure how to fix the high idle for sure. I think part of my problem was that the upper honeycomb was taken out. Make sure that's not the problem. might try adjusting the BISS also.

As for the exhaust, I've decided that when I get my next one, I'm shooting for the Apexi N-1 with the removable insert in the tip. Supposed to sound "close" to stock with the insert in, but be full 3" with it removed. Down side is the $800 for a complete new exhaust. Marcus was doing some experimenting with a flowmaster, that might be an alternative.
