Bull-X Downpipe 3″ Subaru WRX STI 2.5 300 hp

The 3″/ 76mm downpipe for the Subaru WRX STI of HG-Motorsport can be replaced 1 to 1 through the serial part.

Perfect fit and high-quality material make this product a top product from our range. There is no impact edge on the turbocharger output. By optimizing the diameter, piping and catalyst (if selected) of the turbocharger can be greatly relieved. A lower back pressure and thermal relief generate a significant increase in torque, power, previous response and the same time an extension of the lifetime.
By request, you´ll get the downpipe with a reducer and a 20cm, 3″ long coupler to drive continuously with 76mm, 3″. This size is for the EGO-X exhaust system.
If you have another exhaust system installed, which has another connection diameter, please contact us. We can customize on any measurement you need.
