While I don't know what to say, I don't want to say anything bad about the Made in India parts, but when I received the parts I was shocked. First, the rust covered about 1/5 the area of the inner surface of the flange. Then I took it and shook the muffler, guess what, I heard a sound like sand hitting, I don't know what fell off in the muffler, maybe just extra metal or solder if I'm lucky, or rust has already formed in it if i'm not lucky Also, this muffler is much lighter than my previous Bosal muffler (possibly due to rust in the old muffler). In short, first impressions, BAD quality, BAD production. I put it on my car on 10/31/2015, a week has passed while it works well, fairly quiet, no obvious differences from the previous Bosal muffler. Let's see how long this lasts, god bless my car!
