Let a business person try and make it right.
I really wish people would come back and let a business make it right instead of just jumping on the internet and raking a business over the coals. Uness a muffler is special ordered, and then only in extreme cases, all our mufflers are Made in America. I wish you would come back and talk to me instead of taking someone elses word for it, especially when they knew thats probably what you wanted to hear.
I would invite you back so we can make this right.
Cheap Chinese mufflers cause more problems than savings.
I had a muffler installed on my class b RV/camper. This was the only place in Tulsa I could find that had an outdoor lift that could handle it.
The muffler broke at the pipe connection on the road after about 2500 miles, (3 weeks). Luckly I was able to find a reputable mechanic on the road who weldedl it together. He said that the muffler was a cheap POS made in china, and next time I should by a quality muffler like a Walker ect. The poor installation harnising that was done at B&S also contributed to the failure, because the muffler lacked proper support.
