I got the pipe diameter and size of the original muffler, then ordered this one based on required size. The original system was stainless and both pipes were in very good shape, so I was looking for a replacement muffler that as not going to break the bank. The vehicle is 18 years old, so the only other parts that I found were CAT-back with both pipes included priced almost 6X the muffler alone. The old muffler was cut out and this one welded in, and the system is good as new.

Highly recommended
