Hi, last weekend i replaced my up pipe, for one decated, but now i hear a strange sound from turbo area, something like pft pft pft pft pftpft, only start on boost, i already checked twice to find any leak, but nothing, no smel no strange noise, the boost gauge still do the same pressure. The sound only start when boost start, on first time looks turbo spool, but doesnīt make sense because after turbo i didnīt change nothing this time.

Is it normal this noise with decated up pipes?

I already checked is ok....

Is a very strange sound, i lost all day verifying everyting and nothing...

When start making boost i hear something like turbo spool sound, but isnīt from back box is from turbo area.
