I remember reading a while back about someone purchasing a mongoose down pipe for the subaru and it gave yellow(?) flames out of the exhaust when changing gear, was this correct? As I am in the stage of doing some modifications to my subaru impreza wrx sti version IV type-R coupe, and I would like this. Also what is the best induction kit for bhp? Blitz or?

many thanks.

 

Fit catless exhaust and vent to atmosphere dump valve....wait for a pull by the police!

Can someone techie explain whether this also damages the turbo over time? If you've got an expolsion occuring through the exhaust, surely this will affect the turbo impellor too?
