Hi I have a 2005 scion xb I want to put a muffler on. What size would I need? Thank you

 

Most muffler manufactures will state what vehicles it will fit. Just look it up and put your vehicle info in and it should tell you what the part number is.

What ever you do, DO NOT GET A ONE SIZE FITS ALL AND TRY TO STUFF IT IN A SPACE THAT IS TOO SMALL AND ENDS UP HANGING WAY OUT THE BACK OR ALMOST DRAGGING ON THE GROUND!
