Engine Performance problem
2006 Scion tC 4 cyl Two Wheel Drive Manual 60000 miles
Hello my boyfriend is the one who drives the scion and he added a new exhaust system a while back that included a glasspack muffler that is broken now. I dont know anything about this stuff and I can't ask him. His birthday is coming and obviously I dont want him to become aware of what I'm up to so I just need to know how I can determine what to do to replace the broken glasspack without replacing the entire exhaust system. Thank you.
