So I recently purchased the Perrin turbo blanket, Perrin Heatshield, and Cobb DP. Pretty pumped for these to go on Friday! I know I will gain power from the DP and improved turbo flow (finally.) From what I have read, the rumble will still still be comparable to stock, which isn't an issue.
My question is, will I still have the amazing turbo whistle that I hear from the videos? As far as the down spool. I am aware that a complete turboback will allow the whistle to be audible, but as of now, I'm not heading that route.
Thanks!
