Any one ever used lightning headers.They seem to have a good price? Good results ?

I installed a set on a jet boat I had a few years ago. Mine were not the full stainless steel so I made sure I drained them after every use. They were great. They fit perfectly but with no mufflers it was very luod which is the way I ran it most of the time anyway.
I dont think you would be dissapointed but nowadays mufflers would be a must.

Jerry.

They were on a boat that I owned from 03 to 05. They were great (stainless) and are still working fine now for the current owner. I would recommend them....and they are LOUD!!! See picture below.

I've installed several sets. They fit great and have held up fine, in fresh water. I've had a set for 5 years and they show no signs of rust. They are the standard header with non stainless outer tubes.

Same here.

We've put the stainless units on many boats, including our own.

4 years on these with no sign of trouble.

Who Makes Lightning Headers ? Are They Available For 496 Ho's ? How Much ?

They are made by Lightning in CA and no, they do not make any for the 496.

We have them listed here;
