OK i told my machanic to put a resonator the mid pipe as the sound was too much. I just had the new pipe installed the sound is very very nice but the car won't go above 8-9 psi.. starts hesitating... Also the exhuast pressure at idle is much less??



I was having boost problem similar to this before but at that time the wastegate was not properly hooked... Yesterday when i took off the midpipe to have the resonator insatlled before that the car ran great at 12 psi..



should i remove the resonator?
