i have a 98 subaru legacy gt , what i wanna do is put a performance muffler on the stock pipe they all say universal but then say make sure of your cars inlet exhaust pipe size i can not find the size anywhere
Can you get a measurement around the pipe before your muffler, the circumference I mean? If so measure around the pipe and do some math. Take the circumference measure and divide it by 3.14. The result should be your pipe diamater. As most exhaust pipe is measured in intervals of 1/4 inches it should be pretty close.
