Tried looking up American Hi-Tech on the net but came up with nothing. You have a link?

Here you go

www.hitekmarine.com.au

Would they fit on a 525? I only saw headers for the 496 and standard bb on their website.

CMI junk!!!!! I had 2 sets leak and everyone I know had issues. My bud locked up 2 engines and bent a rod because of those ****ing things. My brother went to stainless marine and didn't loose one mph.
My bud,S fountain with 200 hrs needs a set and we put header drains on it. the forward set is 5k wtf JUNK!!!!
I will never have a engine with those things on it ever again!!

I wish I could of heard the audio when they were trying to get at the header to head bolts.

The banner behind them says 525 EFI, 600sc and 700sc with a comparison to "brand X".

I sent them an email, I'll see if they reply.

Those look like nice exhaust manifolds, but I am not sure of the tube configuration inside the outside large jacket. Maybe someone who looked up close can let us know how they are configured inside.
Also, I think there was just recently a post on OSO about HiTek exhausts with some troubling comments? Seems like everyone here could use some real info and updates.
