Review on 🔊 BORLA 400486 Performance Muffler by Dennis Reed

Very good construction, looks very good inside. Across the style. I'll do an update on the sound. I expect nothing but Borla's amazing quality. For some the muffler that is closest to the original TRD (Dual Straight Through Muffler System) except the price is 5 times lower than the Toyota TRD. Update 2/6/19: Well I can believe I'll say that. I am returning this product. Pros: More power, better acceleration, 2 to 4 mpg improvement, nice sound. Cons: Contrary to what Borla advertises, this muffler has a very annoying hum (between 1800 - 2000 rpm in my case) and I just couldn't take it anymore. So I went back to the OEM Toyota muffler (less powerful but good enough to cancel the hum). All the best.
