y pipe options

[Max-Read]

Hi guys, new one to this.

 

I've got a basic set up on my z got a Motordyne plenum and berk de cats currently. I'm looking into a y pipe and i see Stillen, Motordyne or cobra are the ways to go. I have a standard y pipe back section and I'm curious if a new y pipe will add a lot of noise?

 

any info would be appreciated!

[MITZ@CougarStore]

Adding an aftermarket Y will free up breathing and a little more noise only because the OE Y is restrictive...

ok cheers! its more the noise im concerned about.

 

Any recommendations on what y pipe to go for out of the 3?

Your de catted and your worried about an aftermarket Y pipe noise increase . I jest . Stillen seems to be the top choice for most and the member Tuck has one for sale in the 350z for sale items if your a DE owner, shouldn't really tell you that because I'm thinking of buying it myself !!!!!!!

Welcome to the forum

Torqen currently is running a deal on the stillen this month too.

Stillen is the best option in my opinion. I went through two y pipes with flexi's so the stillen was my best option/no flexi's as this seems to be their weak point.

Thanks Mike!

A word of warning regarding the Stillen - on my car with decats it made a hugely irritating hissing type of sound around 1900rpm when off of the gas.

It's a quality made product but it drove me nuts so I sold it.

Funny, i've noticed a little of this too with my Japspeed decats, but the popping and crackling on over run persuades me to ignore it

yeah i've got the small hiss with mine currently, it hasn't got to the annoying point quite yet though. Just enjoying the noise

how much difference will a stillen y pipe give bhp wise?

 

A bit off topic, where's the best place to go for the remap, ive heard abbey and Horsham dev?

Want to make sure I'll get the best out of the car and mods when its done!

Either one of those are well rated on here.

Im having issues with my stillen y pipe its hard against the floor on the passanger side i have berks hfcs fitted also. Any idea why its not fitting? I have a uk de.. could i of maybe been sent one for a hr or does that matter?

[SHEZZA]

Y pipes are the same for the DE and HR, only the cats are different between the two models.

[LDUNKZ18]

So could it be my cats? They fit the headers no bother surely thats where the difference is on the hr?

[LDUNKZ18]

Im connecting a isis gt single exit to the y and the middle box is against the prop shaft.. no idea whats causing this.. y pipe cats or shape of middle section itself. Any help is appreciated

[veilside z]

I bought the Stillen Y from Adrian at TORQEN, still yet to fit but looks an awesome bit of kit. :)

[veilside z]

The more sounds available ... the better.

[veilside z]

Take out the centre box, I have.

[veilside z]

Both do the same..Which ever closest to you.

[LDUNKZ18]

Might be an option... take out centre box and get a custom one made to fit and make it more of a cylinder than an oval box
