Review on Enhance Exhaust Performance with Flowmaster 942051 2In(O)/Out(C) 50 Series Df Muffler by Evan Haynes

Series 40 seems to have too much harsh + poppy almost brushy sound that is extremely loud on smaller engines. It's all about that bass and hearty hum, it won't draw attention but it won't make people wonder if you're overcompensating. Believe it or not, you need some back pressure on the exhaust, so keep the standard pipes, or at least the same diameter and length. Noticeable HP increase! The inside diameter is just over 2 inches and the bushings are THICK - be careful if you're not a welder. A 1995 22RE 4x4 toy pickup that my only regret is that I didn't get a long range model :/
