Bakes100 Posted November 3, 2011 Share Posted November 3, 2011 Hello! Im thinking of buying an aftermarket y-pipe for my 06 350z which will be used with the standard rear system. I notice all the y-pipes seem to have a 3" outlet size whereas the OEM system has a smaller sized pipe IIRC, does this cause any issues with sound/performance or does it make no difference? Thanks Stuart Quote Link to comment Share on other sites More sharing options...

Thanks Stuart OEM ones are more restrictive, Aftermarket ones such as the Stillen give better airflow, better performance and better sound. A popular set up a lot of members have had from me is the Berk HFCs/ Stillen Ypipe and Scorpion back box. Theres quite a few different options though, feel free to drop me a pm if you want some advice etc Quote Link to comment Share on other sites More sharing options...

Bakes100 Posted November 9, 2011 Author Share Posted November 9, 2011 So just to confirm going from the 3" collector to the 2.5"(?) standard system wont cause any nasty rasping sounds?? Iv read in a couple of places that this can happen Quote Link to comment Share on other sites More sharing options...
Wasso Posted November 9, 2011 Share Posted November 9, 2011 Not sure on the sizes of the Motordyne XYZ pipe, although I run a standard back box, Japspeed decats and the Motordyne XYZ pipe with race cat. Sounds great, costs a tad though.... Great piece of engineering and for me the sound at 4k+ (as quoted by another member) "Sounds like a Nismo" yet all I have is decats and XYZ pipe. Made me I've got a link to a video if you need it. Quote Link to comment Share on other sites More sharing options...

Mrev2 and a 5/16 spacer on the way now though to keep me occupied Quote Link to comment Share on other sites More sharing options...
