Delkevic 4 into 1 megaphone exhaust

[Biebs]

Bought this exhaust for my 92 Nighthawk CB750. Anyone else have this exhaust??
I have not installed it yet will update after install. Just asking after purchase for any input.

I bought and installed one, turned purple in less than 10 minutes. Hate the screaming, cackling sound. I consider it a waste of money.

Can only comment on my experience-My opinion good for the price point...the headers are not double-walled so they will discolor-FWIW on another forum I commonly ride with they class it as equal best sounding bike (next to a 1200cc Triumph)....

Quality, no issue, with fit.

I did get "raw stainless" as had poor experience with chrome on aftermarket exhausts rusting within months -nothing like OEM....

Other option is Marving but thats 3x the price point.....
It is loud though about 95DBa at 3600rpm (those low revs are used as std in tests here...)...at high revs on a long trip=headache without earplugs.....

**My bike hasn't had a tub (wash) in months but it you want a pic of pipes after a 2-3years can do....

Got the exhaust today. Stainless do not have a moisture issue is Arizona desert. I expect the pipes to blue.
I will update after installed. Thanks for the input.

I expect the pipes to blue.

Personally, that's one of the things I like about stainless exhaust.
I was never a big fan of 4 into 1, even back in the '90's, the last time I had one of these bikes. I've got a cheapo 4 into 2 on mine now, because it came that way. When it rusts out I expect I'll have to go to the Delkavic, because I can't find a replacement 4 into 2 or 4 into 4 set that doesn't cost more than the bike.

Have it on mt 82 750F, love it. I raced bikes and learned to ALWAYS wear ear plugs so not loud for me at all, love the sound.

Exhaust installed. Very nice exhaust easy to install.

Sounds good. Megaphone muffler goes past the rear axle.

looks good...sure you know but just nip up the exhaust nuts after a few heat cycles..

Quick update:
Bike now has more midrange power 3000 to 5000 RPM. Rode with no Helmet and it is not to loud does backfire on Decel.
I normally ride with a Helmet so no need for ear plugs.
After a couple heat cycles checked exhaust nuts - couple loose nuts.
Have a new set of exhaust nuts on order $6.00 each total of $50. Honda OEM parts. Old nuts are rusty and beat up.

Now what to do with the original Exhaust - Hmm anyone in Arizona - Phoenix area need one??
Very good shape no rust.

Too bulky and expensive to ship.

Installed it to my 79F. Fit and finish are great. No discoloration as of yet. I did find them a bit “raspy” when rev’d up. I bought some muffler packing and wrapped the baffles. No change in performance and it did quiet it down some so it’s not barking in my full face helmet.
