Review on TOTALFLOW TF-SY2525 409 Stainless Steel 2.5 Inch Y-Pipe Single / 2.5" Dual (Inner Diameter) by Kenneth Foster

Revainrating 5 out of 5

No More Droning. good for me

I bought this to install on my 2013 BMW X6M (E71). The previous owner already took the muffler out so I got a lot of droning noise inside the car. This little thing fixed the issue. The change of noise is huge and the exhaust note is better now. Also I felt a very little more torque on the low end RPM.

Pros
  • It does what it’s supposed to and it’s held up nicely since I had it put on about a year ago.
Cons
  • Poor sealant application during manufacturing
