WHERE'S MY WHISTLE?
Looking for information on why my exhaust tone goes to a deep tone and then sounds like my turbo is spooling up to a whistle and then drops back down to a deep tone. This happens while at idle. There is also an air leak sound coming from the area around the turbo which starts and stops corresponding with the change in tone. Any information is greatly appreciated!

My 07 does not sweep at all, another member advised me to take to a dealer here in Iowa and get it re flashed cause the Cali tune is weak. Whonder if thats part of the Emissions tune from Cali?

i have the whistle except while sitting idle. sometimes sitting at light or parked is when deep low tone appears for about 30 sec. then i can hear the turbo spooling and then whistle for about a 1min. then deep tone again, or i can tap on the gas and deep tone stops, then starts again? should i be concerned?

You have to replace the whole down pipe Im afraid. I noticed a replacement down pipe on ebay that was 3.5" for like $157.00.
