350z y-pipe question

[barak7]

I'm looking to install an after-market Megan Racing y-pipe. Has anyone out there done the same, and if so, what can I expect in terms of added performance and also, will my exhaust sound different?

I doubt you'll notice any real change in performance ro sound, might show a few horses on a dyno but don't expect anything more than single digits from bolt on parts, big gains are had only with forced induction of full engine builds
