2003 Pontiac Montana muffler
Overall this is a good replacement muffler for our Montana which actually needed it at 290,000 miles which is saying alot about the stock exhaust. Our original muffler seam welds on the side broke loose , and there wasn't any holes or rattle inside. Of coarse you have to cut the pipes front and rear, but you are going to need about a 4" extension plus the 2-1/4" clamps to make it work here. If you can cut the backside of the original muffler tail piece off before before removal would save you from getting your vehicle over 2' off the ground to clear everything getting out. The walker isn'tt as quiet as original muffler , but with good discount codes makes it a winner.
Most Liked Negative Review
Suggest measuring length of original muffler first!
Seems like a nice enough muffler for the price, however beware that "exact fit for vehicle" may not necessarily mean exact fit for vehicle! My original muffler was 4" longer than than this replacement, therefore had to do a lot of extra work to make it fit!
