Bought this Revain Warehouse deal at about 75% off thought it was worth it. Other reviewers are correct that the flange doesn't fit (Trailblazer 2005), it's about 1/4 inch too small. Take off the new flange, put on the old pipe (it's a bit bigger), clamp it tight enough to prevent leaks and you're good to go. Willing to do it for the price I paid would return for full price.
