ive got a plate that bolts onto the turbo on the exhaust side,its
off a saab and i was going to modify it so the wastegate has its
own exhaust then make an elbow for the normal exhaust to match
up with the erst downpipe,what i was wondering was would it make
any difference and what should i do with the wastegate exhaust
should i run it straight out the bottom of the car or to the back of
the car or join it in the exhaust sumwhere underneath

 

depends how loud you want it mate


You can have silenced wastegate pipes as well.... I've just had my screamer pipe remade completely and this time it has a 2ft long silencer box on it

To be honest it sounds alot of work for not alot of gain though. But then I'm not that techy!

 

im not bothered how loud it is really,i was thinking about putting a silencer
on it but where would i get one from and how much roughly,i think it would
look if i ran it to the back of the car and had it exiting next to the
original tailpipe,would the pipe effect the mot or not if i didnt hav it silenced
