Hey people, i just got a Stillen Y-Pipe couple days ago and today had time to take it to the shop to be installed. Along with an after market B-Pipe with an resonator. When the installation was completed took it for a test drive, and i have to admit i have noticed a little change in my take offs. Well to make the story short, when i give gas it makes a whistling noise till 3500RPM and at 2000Rpm i feel a little sputter. How can i get rid of that noise? Do i need to take the resonator off? Well any suggestions would help. Thanks.
