I am the type of person who likes to do his own repair or upgrade.
For the life of me I cannot get my cat-back exhaust upgrade to sit with level or flat horizontal muffler's. They are at an angle of probably 10 to 20 degrees. If I position them level the tailpipe and tips are way too high. What am I doing wrong? Should I just force the tips down after tightening? Is the angle safe enough to drive? Is this normal? Magnaflow directions are very vague. Magnaflow street cat-back. 1994 Mustang...
