aite people i have the turbo xs race pipes but im thinking of switching them out to the AAM 3inch open dump down pipes..my 350z is boosted so im sure the AAM may help..now my question to you all is..would it be worth it to spend almost 700.00 on those AAM downpipes or just keep the turbo XS race pipes.. i believe they are only 2.5inch pipes. give me your feedback?

 

Go 3". It will b worth it

 

all depends on what turbo/sc kit you're on in the first place and whether you can live with the noise an open dump setup makes
