what if replace the presilencer by a pipe on TII (no cats) ?

3" piping and only one silencer on the back..
prolly would have to port the wastegate of the turbo or it would boost creep right?
but that's not my point.. would it be too loud , or the turbo would kill the noise enough to use it that way ?

thx in advance

what about noise ? I was thinking about a really low restriction mufler (apex'i GT spec, what U guys think of it ?) so I guess it would be REALLY loud.. :P

about the fcd.. man, port ur wastegate !!

Simple solution to the problem just get a RB presilencer, and install the mufflers
of your choice. Your going to need a FCD, along with bigger injectors on the secondaries like GSL-SE's or 720's with the resistor mod. Port you wastegate. As far as noise is concerned, Ive heard any of the APEXI series of exhaust like the GT or N1 series are loud on Turbo-II's.
