I need a muffler for a 76 280. Been driving it since 1980. Looking for something not radically loud. Car is basically stock and I want to keep it that way. Don't need headers and I just changed the cat. Direct fit preferred. Magnaflow?, Flowmaster?, Bosal?. All suggestions appreciated.

Dynomax Turbo . I bought mine from Summit Racing. they are not too much money , but most of all have a great sound and free flowing. Not too loud. My Z sounds like a E-Jag. Much depends on the size of the exhaust pipe size. I am running a 21/2'' which is louder . So if you have anything like a 2'' or so you wont have any trouble. I looked and listened to Magnaflow and Flowmaster , they have a raspy sound so if this is what you are after there you go...

I am too looking for a muffler as well. What is the stock exhaust size? is it 2 1/4?

I have been reading about the dynomax turbo like beandip has recommended and it seems nice.

You can still get a Monza "cat back" from Pacesetter for 260-280. (240 is disco.)

I installed one a few weeks ago, went on without effort and is alot quieter than I would have thought from reading posts concerning it, although it isnt burned in yet, Ive only driven 10 miles on it. A bit louder than the generic that was on there but not much.

It does stick out further from the rear but I did notice in my short drive that I didnt notice any fumes, a big plus IMO.

You can get them from Black Dragon still or do what I did and go Ebay and save about $40. Got it in 3 days and it was perfect from this place.

I'm also looking for a muffler. My 78 280z has the full msa dynomax exhaust. Since I replaced my bumpers and shaved the rear know I have about 8 inches sticking out. I could always cut the pipe and shorten it, but the car has a meaner look and I want a muffler that would go with it. I was thinking apexi,dynomax turbo and also megan has a muffler that I see alot at the Z shows. Any suggestions.

Monza is great.

Once it burns in it's kinda like a nice old Marshall Stack with a Les Paul...........great sound. I got mine for my 240 before it was discontinued.......love it!

Great, that will give me something to look forward too. I maybe have 20 miles on it since the install. I am getting to tear into the rear end next so it might be awhile longer.

Im not thrilled with the 280 mufflers looks, the 240 (vertical) looks much nicer.

I agree with everything Beandip wrote. With the stock manifold a 40 series is not loud at all. With the header, I had to add a glass pack in the middle of my exhaust. Here's my thread, currently just below this if you're curious to hear the flow with the glass pack. (Post #9 has my digi cam movies, turn on your subwoofer )
