This fits the 75/76 F, 77/78 F, 77/78 K, the A. It is the one they developed for the DOHC F and due to the nature of it's construction it fits OUR SOHC4's

First impression: Polished stainless shine not flat. Looks kinda chrome but not as much as my Kerker. I'm sure you could polish it to a higher shine if you wanted to. LIGHT WEIGHT.
Second impression: Damn thing was put together in 10 minutes!! EASY! Took as long to unpack/unwrap it. Each pipe and each collector hole is numbered. The springs come with a tool that makes it really easy to install each pipe into the collector.

Third impression: Delkevic weight 9.6lb. Stock weight with the collars 17lb. Collars are not needed or so I think so far.
Fourth impression: WOW!! Installed just as quickly as putting it together. Totally amazed SO FAR.
I do not have their muffler yet. A new style is due later this month. I test fitted my Mac chrome muffler but don't like it due to the collector angles differing. My stock muffler would fit BUT I ain't going there

The collector OD's are the same 2.5".
Sure looking forward to firing up this big bad ass #$%*!!

As it arrived

Unpacked

Test fit

Test install

With all this being said, I gotta take it off to install the oil pump now. I thought it may have the 4 exhaust gaskets but it does not. It did come with the muffler mounting hardware though I didn't get their original longish muffler. Oh, you can do oil filter changes too.
