Replacing Y Pipe On The V

[mellowman]

Good Evening All,

long weekend here in sydney woohoo...

I am needing to replace my oem Y pipe and wanted to know if swapping out just the stock Y pipe with one of those polished stainless steel ones from the US would increase the performance/power of the car?

i have seen Y-pipes that are 2.25"inlet and 2.5"inlet and really have no idea which one to buy.

what should i be looking for when purchasing a Y pipe?

thanks guys

Just changing the y pipe and nothing else in the exhaust train is not likely to change horsepower or torque in overall quantity.

What it will do is change the characteristics of where max torque and horsepower are produced by your motor, ie you can have a stonger bottom end but will sacrifice some of your top end power. Alternately you can have a bit more towards the top of your rev band (this may suit track work for example) but will be a trade off with some loss of low down torque.

Smaller pipes flow better at low rpm but restrict top end flow. Larger pipes the opposite. But if all you are doing is the y pipe then doubt it will be significant either way.

I have not heard anyone say that the y pipe is restrictive in our motors. If you want to make a difference you need to consider hi flow cats and/or extractors and a cat back system. Unfortunately big dollar items.

You might be interested to look at the 350z HR Y pipe.

hey mate i purchased the ichiba stainless ypipe from the states and it bolted straight up with no issues. Its yours if you want it for $200, its practically brand new only about 1000klm on it as i upgraded to the motordyne exhaust and it comes with its own ypipe.

Thanks for all your feedback guys much appreciated.

will be checking out the 08 350z pipe.

Hi Robbo33,

did you add the ichiba y pipe to your stock setup? did you notice a change in acceleration characteristics from stock? like better acceleratio down low or in the top end?and did this change the sound of the exhaust much?

also where abouts are in you oz?

thanks all

i got it installed with high flow cats and definately made a difference low down and a deeper sound id say most of the sound was due to the cats. I already had an aftermarket catback installed.
