He doesn't mention, Pat Michal, the headers on his web page, but as far as I know he is the only one who has bothered to build a real collector into the GTS headers?

A 3" collector is necessary to make the headers scavenge. That is one of the benefits of fabricated tube headers.


It would be interesting to add a thread to this on what the decibel level readings are that everyone is getting from their systems, EVEN STOCK!

With the availability of the free sound level apps for smart phones, this is a piece of cake.

At this point just saying, stock, a little louder, etc, can be put into numbers so that EVERYONE has a reference to what can and can not be done sound wise?



I'm getting flack from people who are just looking at the exhausts and telling me they are illegal. They haven't even heard them run.

I don't know where that is coming from since I keep looking high and low and can't find one violation in the statutes.

It might simply be that people don't believe this is a production '73 model year car? They want to know where the catalytic converters and the air pump is?

Anyone out there that has experienced being stopped for "roadside examination" on their cars like the CHiPs still do occasionally in CA?
Well, they are not stock. They look rougher than my GTS headers. Mine may have been repops. They did not have the tooling marks in the tubes like yours do.

They maybe original factory gts headers by the original vendor? They are definitely tri-y's.

As such they are giving away about 30hp on the top end but provide more low end torque off of idle.

They work best on a basically stock engine. They do not work well on a high performance/race engine.

Doug, I haven't had any problems with CHP in So.Cal. I drive both my 67 mustangs and pantera on weekends mostly. No issues what so ever with the CHP. The BAR does set up a road side random smog inspection complete with dyno but I have read that its voluntary.

I suspect it will get more and more difficult to drive these cars as the years pass.
George is correct on the primaries. The exhaust pipes are actually 60mm (2.362"); tail pipes (tips) are 70mm (2.75").

Wilkinson also sold (as a set) stainless steel headers and mufflers. These were also available in mild steel. Primaries are 45mm (1.77"); exhaust pipes are 60mm (2.362"); tail pipes (tips) are 3".

I don't know what he is currently selling.

John
