Aftermarket Y-Pipe with standard system.

[Bakes100]

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

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

Stillen y pipe us the way forward

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

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.

Ah that's ok then. I'm thinking of going for y-pipe then hfc's. Back section to come last at a later date!

 

Mrev2 and a 5/16 spacer on the way now though to keep me occupied
