If u had 2 headers...
One header made 12RWHP/12TWTQ MORE from 2500 to 4000 but lost 5RWHP from 4500 to 6600 to the other headers.

What header would u run on your car.

I believe the header making the better power in the AREA under the curve (Down low) would be the one to run since its generating more power as u launch the car

I think the STEPPED Dyna is too big for my 346 even with my stout setup.I want to go back to a
1 3/4.Does this make sense?

Put the thruster pro in there and don't touch anyhting else until the good weather gets here. Its time for small changes to get your car ready for the -2000 DA <img border="0" alt="[Fluffy]" title="" src="graemlins/fluffy.gif" />

As for the header question I'd go with the top end and let my converter take care of the bottom

so what 2 headers are you comparing?

 

Did you back up these dyno claims on your car or are you guessing?

 

JS I think the MACs will be faster all around.
throw those suckers back in <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> hehehe
That and the TP4400 will be tens. Also your daily driving will be more pleasant as well. What catback are you running?
Cheers,

I have dyno runs that prove the MACS are better.
I made 12/12 MORE at the wheels from 3600 to 4900 using the Macs.

The DYNA's only out powered the MACS from 5000 UP and then it was only worth 5/5..

Others have lost power going to the Dyna also...
I forget what shops tested them on some cars but they lost power.

IMO the MAC is a better header for my combo...
I agree w/Bob though.I wont make any more changes except going to the YANK 4400 FIRST.Then if need be I'll put the MACS back on.
