there is only one problem with straight pipe is that i can no longer hear ANY cold side turbo whistle.
not saying i wish i hadn't done the straight pipe but the noise on acceleration is a bit obnoxious. it's not loud, but the tone of the exhaust is not my taste to say the least. I REALLY like the sound right around 1500 rpm, it sounds like a Cummins and you can hear the turbo start to spool up
, but once you get up over 2000 rpm it just sounds like i am at red line. there is no in-between.
i have also lost about 3-4psi of boost with this. i am going to look into the WG more for that though.
