N63 N63TU Downpipes

TM Performance N63 N63TU Downpipes feature a 3" construction along with a stainless steel v-band to pipe transition that is machined with CNC to precision. Our downpipes are the best bang for your buck mod available for your N63/N63TU engine with gains from 50 Horsepower and 60 Torque when tuned. Rather than necking down closer to the turbos like most of our competitors, our downpipes present a full 3D design up to the last inches proving a greater increase in flow. Project Gamma downpipes are handcrafted to extreme rust resistance using 304 Stainless Steel.

Various version for you to choose:

with heat shield/without heat shield/with high flowing catalytic converters/without high flowing catalytic converters

 

 

*Manufactured from high quality 3" stainless steel pipe for superior heat resistance and strength. These stainless pipes replace converters for additional power.

*TIG welded and CNC machined flanges for strength and durability.

*This increased exhaust gas flow from this reduced restriction allows for more power in the low to mid range RPM. Generally around 10-15 HP

*Comes complete with O2 sensor bungs, braided stainless integrated flex pipe for better alignment, gaskets and bolts.
