View Full Version : Exhaust note and misfires still

09-13-2016, 10:01 PM
So i went and built a dumb exhaust for the car finally. Its 3"->2.5" test pipe then 2.5 all the way back to a magnaflow 14816 muffler. Under boost it stumbles in positive pressure and sounds strange. As if it was misfiring. All i changed though was the oem muffler and pipe to accommodate my new muffler.

It also doesnt happen while parked only while moving. Ill get some logs asap also for my other issues too.
