A few different problems just popped up in the past week
, a week ago i had just a magnaflow exhaust installed and the resinators removed, not a catback just mufflers for now, since having that installed, ive noticed when its in 3rd gear roughly just below 40mph cruising speed when i press the accellerator just alittle it hesitates alittle up & down until i really punch it. And it wistles alittle after the rpms come down, down breathing enough? Another problem i noticed now, seperate from the exhaust is on the highway it wobbles now? if anyone has any ideas that would be awsome thanks
