I highly recommend Motordyne ART pipes. They are amazing quality and also amazing sound, not as loud as regular test pipes just a very deep and smooth sound. Makes the car rumble at idle. They have a 2.25" ID and 2.5" OD. Plus they have much higher TQ dyno readings than other test pipes with less rasp/ hiss! Enjoy!
