What is the cheapest y-pipe out made for the Z? Just wanted to open up air flow a little more but didn't want to spend 400-500 dollars. Anyone know of any?

 

I've recently ordered NFC Motorsports $285 stainless Y pipe. Cheapest I've found.

 

Same here, this is the cheapest one I found. This is the only one I know of that has the stock pipe diameter. All the other Y-pipes are bigger at 80mm.

 

Gains with this one compared to others?

 

I've been told that the Y pipe was responsible for 60% of NFC's 10HP full exhaust. Pretty realistic compared to other exhaust out there.

 

does that y-pipe have flex pipes?

cutting corners in some places means spending more else where later on...

 

No, the NFC y-pipe does not have flex pipes. That was a concern of mine regarding this product but after talking to some people, one of whom has his own custom y-pipe with no flex sections, there doesn't seem to be a problem not having flex sections. Since I have recently purchaesed the NFC y-pipe, I will find out soon enough if that is true or not.
