99LegacyB4

another question. when the car is parked if i jam the accelerator or manually pull the throttle lever the little black square electric thing on the intake manifold where the air cooler is plumbed in makes 3-5 ticking noises really quickly then the engine revs up. takes about half a second to make the noise. I have owned alot of vehicles with cable throttle bodys but never heard it tick like this before reving up.

duncanm thanks man i really appreciate the info!

Do you happen to know the size of the stock exhaust on the axle back part? i have a new flowmaster muffler in the garage thats about the right size but its a 2.5 and the b4 looks like its 2 1/4.
