Hey, my birthdays coming up and im hoping to get a nice muffer(cant afford a whole system). Anyway im looking at the HKS Universal Stainless Hi-Power muffler for my 94 stealth r/t but dont know what size to get. They make 2 sizes, on size piping 60mm and one 75mm. Im guessing i want the 60mm piping one but not sure....

 

does anyone know?? i need help asap

 

Measure your exhaust pipe that connects into the muffler. If you don't have calipers a piece of string and ruler will work using a little math. 75mm is about 3" while 60mm is about 2 3/8"

 

i'm pretty sure you need the 60, but if that's still too big, you can go to an exhaust shop and get a reducer to the size you need
