Review on 🚗 MagnaFlow 12158 Oval Center/Dual Straight-Through Performance Muffler: High-Performance Satin Finish Exhaust (5in x 8in) by Elijah Pope

Used this on my 1989 325i with stainless steel headers down to a 2.5" single pipe down to this muffler. Sounds incredible. A little rumble under load at low revs, but it's smooth and pleasant to drive around town and on the highway. When you crank it up past 3500 rpm it really starts to sound amazing. Perfect touch. great product
