YOLA said:Dang, i think i have a leak then... ever since i installed a downpipe, besides of the noise of my turbo spoolin up there has been like a high pitch, sort of clicking noise. and it does emulate the sound of exhaust.
Eh, a leak after the downpipe isn't so bad unless you have some cats after them causing more pressure in the piping and more exhaust gasses to come out. In the uppipe, the leak would cause more of a performance loss(slower spool) and be louder cause there's more pressure on that side of the turbo. I'm not sayin that it's good to be leakin exhaust under your car or in your engine compartment, but if you installed the header you'd probably notice the leak a lot more.
