36th Mod, COBB Catted Pown Pipe

This mod is a 3" dia pipe frin the turbo down past the cats to the exhaust.




This pipe adds say 10-15 HP on its own but the ECU can be tuned for more fuel and bring the HP up 50 to 280!

Ignore the forester label in the picks they are the same parts.

You will notice the "Bellmouth" of the new pipe on the right. Also the stock pipe had two cats and a bunch of heat sheilds. My down pipe also has an Exhaust Gas Tempurature or EGT sensor bung.
