Review on TOTALFLOW 646 Mini Muffler 409SS 4.5" Round Width 4" Body 6" Overall Length Inner Inlet-3.5" Outer Diameter Outlet by Brian Edwards

I am very pleased with this purchase. I have a 2012 Infiniti M37 and decided to do a resonator delete. I also installed Magna flow mufflers in place of the OEM. The result was terrible drone at highway driving. After reading reviews, I decided to give these mini resonators a try. I was skeptical that being so small, how could they make a difference. I also installed an X-pipe and these were mounted right after the x pipe. Wow, what a difference they made. They got rid of that awful drone without effecting the exhaust tone. I am very glad I decided to go with them.
