Project Gamma catless downpipes for the N55 engines feature a 4” 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 N55 engine with gains from 50 Horsepower and 60 Torque when tuned.

Project Gamma catless downpipes are handcrafted to extreme rust resistance using 304 Stainless Steel.
