Hi Guys, Yes! another exhaust question. I currently have a stock 78 280Z 2+2 and my muffler just fell off. I have a Monza resonator http://i16.ebayimg.com/01/i/000/e6/75/4594_1.JPG that I would like to use and wouldn't be able to put the new muffler in the original location. I was thinking of using a Dynomax turbo muffler http://www.jegs.com/p/Dynomax/744698/10002/-1 by the drive shaft, unfortunately it might be a little tight. Does anyone know of a good round or small oval muffler that I could use. I don't wanted to be loud just a nice sound and would like to also keep the cost down. Another thing, is there anyone running a setup simmilar to this one. Stock engine, stock…

I've been kicking around the thought of getting some monza headers for my 280, and since my exhaust would be in pieces, how about moving the exhaust under the doors? Perhaps like that on the Cobras. How would this look on a z? I've never seen it done before. Any ideas? -Ben

I read the previous posts on this and there was someone trying some customized tip lengths and shapes to help solve the exhaust fume problem. I'd like to know what results he got if he's still around here and can post them. I've go a 73 240 I've had since '76. Its always had an exhaust fume issue with the window(s) down. Since here in Texas we usually always have the AC on its really not much an issue. However, lately the ac is on the fritz and besides it sure would be nice to have a breeze and not be smoked out. The exhaust is an old turbo flow 2.5" from Motosport a long time ago. Basically a big muffler on the end. It has held up remarkably well. I should say that …

So, I don't think I am going to do a dual exhaust on my z, I was thinking of a ANZA muffler. I have a Abarth muffler with dual tips that has been on the car for 15 years, that I put on to replace the factory dual system. I still have the factory header. Does anyone have a picture of a Anza muffler? Thanks in advance, Bob

Need a downpipe

I'm looking for an original exhaust downpipe (from the exhaust manifold to just below the firewall) for my 73. I'm running the stock manifolds and plan to use an MSA exhaust system, but had to cut the downpipe to get the motor out. I could pick up in the Massachusetts/Rhode Island area, or I'd be willing to pay shipping. If anybody has one they're looking to sell, I'd be interested. My email is: sidneydal@comcast.net Thanks

I'm at a loss trying to figure the best option available to complete my exhaust system. I am using the header that came as a Sports Option (14004-E4620) and the second section that I don't have a number for. I believe it was originaly from the same car as the header. It's pictured here. I have never seen the last section for sale anywhere and will have to fabricate one. Here's the question. Has anyone seen or know where to find a 2 in & 2 out muffler such as the original or close to it? Each pipe is 50mm OD or a little less than 2" OD.

What is this Valve?

I am removing my original air filter and adding the K&N "tuna cans" on my Z. I have determined what to do with the hoses that go into the back of the original air filter housing, but am curious about the valve pictured below. What is it? Did it have something to do with the smog pump (which has been removed)? I am probably going to plug the line from this valve to the original air filter housing, was thinking of removing the valve completely. Your thoughts?
