Oh, it is high flow for sure. As in straight through pipe made to look like a cat.

 

I got ya. How well does something like that function as a resonator? I know how the Corsa stuff sounds with no cats. And sometimes its not a good sound.

 

Sure does look like the old style Dynatechs...

 

Why did Dynatech change them?

 

I'm not 100% sure, but the new one's don't have that wierd hump on the driver's side, which seems to turn alot of folks off, as well as cause clearance problems with spark plug wires (which can be remedied with zip ties or some easy home-made bracketry). My best guess is that they re-designed them to elimintate the "hump" and hopefully increase sales...

 

They still look exactly like the Dyna's that are on the Dynatech website. I guess they haven't updated their picture. Except the OBX have the egr crap which is odd that they bothered with that considering those cat looking things are just resonators. I asked the guy who is selling them about em and he confermed that they are just resonators, and he couldn't tell me how thick the flanges are.

 

Tell him to hold a ruler up to the flange and take a pic. Then email it to you and you will tell him how thick they are.

We want to know.

 

I will do that and see what I can find out.

 

At least they do come with a lifetime warranty against defects. So if the flange was of insufficiant size and leaks or cracks I would call that a defect and demand they fix the problem.

 

So since these are stainless and not coated will they still heat up the engine bay like uncoated headers?
