The bends are actually vibrant and the manifold is stainless. The MIG weld on the collector makes it look a little crude but theoretically, it could all be tig welded in the collector, the piping could be mandrel bent and the final product could be polished. It would doll it up.
In the end, it makes power and tq. Thats all I care about.
yea i used the stock manifold and cut out the cats but holy shit can you notice the differnce it actually pulls now, and it sounds like an e46 m3....sickkk. i did alil custom fab work with a buddy and im happy i did it. well worth it and yes it should be the first thing anyone should do
