Just my :twocents:

If I'm gonna spend $30k+ for a car... I'm not gonna look for parts for it on ebay... :ugh2:

That being said, if you're looking to change the tone, and gain some power then go for a full CBE and save for it. You'll be much happier in the end with the gains in both sound/power you get.

If you go the route you're talking now, yes the sound will be different and a lot raspier. However on the performance side of the house, anything you do to the front end to allow it to flow better you will negate with the stock system. If you put in test pipes you're still gonna have the same bottleneck in the Y pipe. If you replace the Y pipe you'll still have a bottleneck in the muffler. Either way all of the 'improved flow' you gained will still eventually get stopped and you'll lose performance at the expense of rasp. Not exactly what I think you're going for.

All in all there are several different CBE's out there to choose from, and each have their pro's/con's and are in a wide expense bracket. Surely one from a good name at a slightly higher premium will give you what you're looking for without any negative side effect.

Not sure who that directed towards, but I can think of many expensive a$$ CBEs that sound like a$$.

There are only a few that DON'T sound like complete crap and still give great gains. In the grand scheme of things, I'm with you on spending money on the right parts the first time.

Besides, most exhausts come from and/or made all in the same place overseas anyway. :-X

Type, it wasn't Directed at anyone. Just kind of an overall statement. Sorry if anyone too personal offense to it. :icon14:

I agree there are some overly expensive ones in my opinion that do sound like garbage. The happy medium is usually the best bang/$$ :tup:

LoL I would agree with that on most of the big named exhausts. But I can say for certain I know exactly where and WHO made my exhaust cause I watched them build them. :tup:

The biggest bottleneck of the 370Z exhaust is the CATs and that awful Y-pipe. Everything past the Y-pipe is actually pretty decent, since it opens up to a true-dual and just flows straight out.

The 370Z is unlike the 350Z, which had a heavily restricted exhaust all the way back.

Just because its a 'true dual' when you have a Y pipe... which doesn't make sense anyways, but still... If you've seen the inside of the muffler, there are a lot of bends. Not to mention its heavy. Cat's are going to be a bottleneck on any car... I figured that was a given so it was ommitted. And have you seen the inner diameter of the Y pipe? It's TINY!!! :eek:

I did not say it's a true dual when you have a Y-pipe...I said past the Y-pipe the exhaust is dual. And yes, the OEM Y-pipe is horrifically restrictive.

ebay test pipes will make just as much power as any other (Art pipes may make a little more) -- BUT, if the rasp will bother you, get a set of resonated ones.

You still call it a dual even if both pipes go to the same muffler?? :confused:

Really, if you have two banks, they have two exhaust paths. Even if they merge somewhere, it's technically a dual exhaust.

If you think about it, the two exhaust manifolds are what really matter. Everything after that is a compromise between a whole host of factors aimed at where the motor will be able to best take advantage of the piping diameter, scavaging, noise modulation, and emissions.

Even the so called "true duals" usually have some sort of a connector pipe between the two paths, and on the single muffler, dual outlet, you still have two paths; it only joins at the Y for purposes of scavaging and noise modulation.

If you have a motor with one bank that splits into two paths is that more of a "true dual"? Does it matter?

K thanks for all the responses guys
