69 Z, Headers, VS Stock Manifold and Chambered

[Chevy454]

Well, since you asked, Pete:

Factory chambered = Crap

It all depends on what your are going after. Nothing beats the sound of chambered, but the factory system is restrictive...and I mean WAY RESTRICTIVE! Flowmaster offers a 2.5" mandrel system which uses it's own "interpretation" of a transverse muffler, or Dynomax sells a really good transverse muffler that looks fairly close to stock and flows really well, but you'll have to bend the rest of the system yourself. BUT, if I was gonna put exhaust on something that won't be submitted to a tech inspection(!), I would buy the chambered system they offer for the new Camaros/Firebirds. The system is mandrel bent, but is a LOT bigger than the original chambered of the '60s. It supposedly adds power to the late model F-bodys, and is supposed to sound AWESOME, so it must be pretty good, because those late model guys won't buy ANYTHING without seeing what it did on a chassis dyno. That, to me, would be the best of both worlds: the sound and look of chambered, but built using today's technology.

As for tips for your Z-28...I have no idea about tuning it, but don't be afraid to REV THE PISS OUT OF IT! Don't worry, your ET's will thank you for it!

Hi,

In Norway they are very easy to deal with concerning tech inspections on cars older than 71. So i dont have to really worry abt. what i am doing concerning sound, etc..

The engine sound really nice and everything, but it is missing something, it could be that it is breathing to little.. Since it is an original car, and every thing is kept original i am really just not sure what to do..

But i think the exhaust, and the smog system does some strange things to it,,, I∆m not really sure, cause i havent run a 302 in any other form than this,
