Madkaw,

That is such a great video! I will watch it often. Hopefully I will have my car up and running soon.

Hey Arne, Do you think I would get close to this sound from a 75 280 with a header, 2 1/2" pipe, a 22" cherrybomb in the middle and the same magnaflow muffler?

Should be similar, but probably louder with the headers and 2.5" all the way back.

For a 280Z you have a bigger selection of Magnaflows for the rear. The 11148 I used was the only one that was suitable for the dual-stacked tips I wanted. Since the stacked look doesn't work well on a 280, you have more choices. Don't lock in on only the 11148.

Thanks for the reply Arne. I was wondering if you could here the fact it was duals. Did you listen to it with speakers on your computer? I have seperate speakers on my stereo and I could here both pipes.

I've got good speakers (w/sub), but maybe not enough separation to tell that it was duals for certain.

My exhaust also has what I call a cackle from the rear that could be thought was valve noise or pinging. I thought some tip resonantors might mellow that out, but you have tips??? Maybe it is a different sound we are comparing.

Sounds like we might have the same noise. Yes, I have resonated tips, and I even removed them temporarily to see if that made any difference. It was louder w/o the tips, but the "cackle" (as you call it) was still there. I wonder if this is characteristic of the Magnaflows?

It might be Arne, and at first it drove me crazy wondering if my new engine was detonating. I am running the shortest magnaflow they sell and it's only 10" long

Mine is longer (14"), but is the really small oval case (3.5" x 7"). But it might not be just Magnaflows. I know of one person with the full MSA Premium system (stock manifold) with Dynomax who has a similar sound. He went so far as to pull the head to look for carbon deposits and hot spots.

Great video man! Either you had pudding before you drove, or you just love to drive your Z so much!

Great clip. I think we should have a thread dedicated to Z clips, in the car, in front and behind. I plan on getting a video camera soon and I'll contribute.
