What year is it??? What kind of exhaust you got???


Most people are DYIN' to get more whistle - maybe you're just lucky


I have an 07' w/ straight pipe, it whistles pretty good all the time. An 03' will whistle CRAZY loud, that's why alot of guys will switch to an 03' turbo.

I don't know bud.

With the straight pipe you'll hear ALOT more whistle from the turbo (that's normal, and good) Is it something new / different? How long have you had the straight pipe on?

When i put in my downpipe i noticed there was a butterfly valve after the turbo. Im assuming that closes and holds some heat in the exaust tell the engine warms up.
