Ok lets start with the basics I have a 87 N/A with a rebuilt Engine 10,000 miles and straight pipes well it has a pre silencer that does nothing. Ever since I have had the straight pipes when I shift at high Rev it will either backfire or throw a flame out each side about 1-2 feet or it will just throw a flame. I don’t know if this is really messing my car up or what someone please give me advice on what they think it is or if this is just normal.
