is a Y-Pipe recommended for a 2006 350z while leaving the rest of the exhaust system stock??

id like to add a little deeper sound to my car but nothing too loud? im not going for performance, just a 'nicer' sound. Ofcourse i dont want to make the performance worse!

i was looking into the JIC Y-Pipe, from my reading most people like that one, is there another Y-Pipe that is better or that more of you have liked better?

 

I like my AAM Y-pipe...as good as any others...great design, welds, and fitment:
AAM's Y-pipe



I'm not sure the difference it'll make for sound, but it might be exactly what you're looking for; the larger diameter piping should make the tone slightly deeper...as well as gain some performance!

I've seen that y-pipes make it a little louder and a little raspier. They also make power too.

The stocker is indeed restrictive.

 

did any of you install it yourself?

most of the reading ive done about them, say you can install in 15 minutes since its a 'bolt-on' part, no modification needed.

is there maybe a how-to guide on the forums? ill go search for it, but if any of you have experience in it give me a few pointers.

 

Um... it's 6 bolts.

How-To Guide:

Step 1. Unbolt the 6 bolts that connect the stock Y-Pipe.
Step 2. Replace stock Y-Pipe with new Y-Pipe.
Step 3. Bolt in 6 new bolts.
Step 4. Drink beer. (Bud-Light Bottles work best)
Step 5. Call it a day.

 

^ Like OCZtrack said.

Its super easy. Its probably the easiest mod you can do.

 

get high flow cats..id say you will get better results from them, but pay more as well

 

What about bottlenecking issues when the larger diameter y pipe dumps the air into the smaller diameter b pipe (usally from 3 inches to 2.5)? Would this not cause a turbulent air flow w/out a cone filter modification to the mid pipe? Couldn't this negate any gains attained from the install?

 

check out the post I wrote w/ my install, it's got a few simple tips to make things easier...but it's a very very easy install-you'll have to push a little on the Y-pipe to get the flex pipes to move enough to get it out and put the new one in.

yes, this would not be ideal...but IMO the gains realized from a new Y-pipe would be more than the losses from a larger to smaller diameter transistion.

 

Wouldn't the sound be affected as well--raspiness?

 

No. Rasp comes from the lack of resonators. Run test pipes or a poorly muffled exhaust and you will get rasp. A y-pipe should not lead to raspiness.

 

from most of the units ive seen its 2.5" dumping into the 3.5" not the other way around. am i right?

heres a ****ty diagram.

/ (3.5)exhaust
engine?---(2.5)ypipe
\ (3.5)exhaust

so back on the subject.

Thanks for the link to the guide+vids, its exactly what i was looking for. for those of you who did insall this part, was it worth it? do you like the sound of the car more now?

 

I wouldn't expect to get rasp from this set-up...


I think the OP is talking about a OE exhaust system w/ aftermarket Y-pipe...the OE cats are around a 2.5", so that connection to the y-pipe should be fine, but all non-OE Y-pipes I've seen have a 3" outlet...which will be larger than the OE exhaust.
