Review on 🔊 Flowmaster 942041 40 Delta Flow Muffler - Aggressive Sound, Black - Offset IN/Center OUT - 2.00 Inches by Vera Gashi

I've been using these on my 2005 Pontiac Grand Prix GT for over a year and a half and they sound really good. I have dual rear exhausts and the stock mufflers lasted about 13 years. Replaced the entire system from the exhaust manifolds through to the catalytic converter, welded everything together including those mufflers and tailpipes. I used 600 degree black paint and coated everything after the Y pipe and thrice coated the mufflers. While they still sound great they are covered in surface rust that started after the first winter. I'm not sure how thick the steel used to assemble these things is, but I hope they last a few more years before they explode. If not, I'll just replace them with Walker stainless steel mufflers. So in the end. If you want your exhaust to sound great and you don't want to drive your car through the winter with all that salt spilling on the roads then this is a very good buy.
