      Comments about Walker Converter - ULTRA Direct Fit:

      Perfect fit. Slid right in (had to cut the old catalytic converter out). This fits the Trailblazer EXT "exactly!" The Magna converter was 4 inches too short despite the website saying it was a "perfect fit." This one is for the longer 129 inch wheelbase found on the EXT models.
