280z Dual Exhaust?

[sblake01]

That looks pretty good geezer.

I wonder what it would look like with both twin ANSA tips on it like that.

Now this is just my opinion but that would look strange like ricey or what's that other term? Bosoku or something like that? Again, JMO.

Ricey? You mean like a rice-burner honda mod car or something?

I'd really like to get them on each side...but like you guys say, there is lacking space for an exhaust pipe on the right backside.

Seperate with one on each side, Ansas or Monzas would look fine. But stacked together or side by side on the same side of the car would look strange to me. Besides, these are single bank engines. I'm not sure that dual exhaust would be good for anything other than asthetics.

A few modifications are in order if you are using the Ansa tips. Not to say it can't be done or that it would offend too many people here.

I am not a purist by any means but do appreciate those who are and also appreciate well done modifications. I am staying a little closer to an original outward appearance, so will be using a set of NOS stacked megaphones that can be swapped out quickly for the stock twice pipe muffler.

Here are those example pics and one suggestion for a 2 in 2 out muffler that I am planning on using along with my stackable megaphones.

Wouldn't dual exhaust (6 - 2 header) let the exhaust flow more freely and improve in getting past any backflow?

Basically giving each 3 chambers it's own exhaust rather than all of them tied up into one.

Here are the ANSA tips - they are basically just dual-tipped (as they stem off of the 1 pipe).

Inlet: 2 1/4"

Length : 10 1/4"

Chrome Length: 6 1/4"

Outlet: 2 5/8"

Interior Baffels: 1 3/8"

Your 2 1/4" inlets are the limiting factor. In my opinion a dual 2 1/4" system is overkill anyhow. There will not be a backpressure problem. More likely a quench deficiency because of an oversized system. I think it will be fine though, just a tricky installation.

Quench deficiency?

I don't HAVE to go with this setup, especially if it will pose any problems down the road...

What do you think?

Didn't mean to scare you, bad choice of words. What I am trying to convey is the loss of maximum velocity of the exhaust because of an oversized system. There are so many factors and combinations of engine builds that would determine this, so it is a matter of following the lead of what has worked for someone else or blaze a new trail and hope for the best. I don't think I have ever seen dual Ansa tips mounted on both sides of a Z before and it would be interesting to hear them. Might sound pretty sweet. Problem is, routing the pipe to the right side, without any interference.

Here's a NOS Clifford dual system as shown in the picture Ron loaded. Still has the cardboard tubes on the chrome tips. I thought about buying it just because, but decided I didn't want it for my car.

I appreciate all the advice you guys have given. I will weigh my options, and see what is possible. I originally bought the pair of ANSA tips; just to swap one of them out for the current tip i have; although I started thinking about getting a real dual exhaust setup going, instead of just a tip that gives the "appearance" of dual exhaust.

If I end up just swapping the tip and scrapping the dual idea --- well, it won't be that bad considering what I have on there now should probably GO.

Considering I decide to go dual exhaust, maybe selling these tips and going with one actual dual tip (2xinlets) might be a better idea. I would like to be able to route the exhaust down the right side, but if this is impossible; then having it dual on that one left side would be adequate (i just don't think 4 outlets on the back left side (2x Ansas) would look very good).

Thanks again!

***UPDATE***

I sold the ANSA tips on ebay after deciding it wasn't going to work. I have my eye on the fluted/stock dual twin-pipe exhaust MSA sells.

Any feedback/reviews on these?

The twice pipes? From what I've heard, the headache of installing them is remedied by the glory of hearing them.
