Currently we only build exhaust systems on a custom basis. Complete systems include cat bypass with expansion joints, polished free flow muffler section, v-band clamps all mandrel bends, is t304 stainless throughout and features a single outlet tip only- Our setup is tig welded for durability and attractiveness and is very agressive- sound is clean inside and out. We also offer a megaphone outlet, non resonated (no muffler section)- It is VERY loud but sounds fantastic and is exceptionally free flow- has a similar sound to a 996GT3RSR at full throttle.
