dude dont fret, if you fall victim to the dyno game you'll never be happy. macs have been shown to support plenty of power especially with the ported primaries.

You would probably gain some low and at the midrange. Macs work pretty well up top. I have not been able to justify the cost of replacing mine. I bought them before the Hookers, Jet Hots, and some of the other reasonably priced headers came out. If I were to replace them it would be with Kooks or QTP's.

I say you keep the MAC headers and try to work with them. Mid length headers aren't too common and they will keep your car more unique. With all the mods you have, i'm sure there's some change you can make in order to compensate for some of the lost power.

I have a custom 3" y-pipe with a Flowmaster collector. That helps alot.

Any pics of the ypipe? Do you think the weakness of the macs is the ypipe and not the midlength primary tubes? Also, how does it sound with the 3" ypipe compared to long tubes?

We saw at peak 14rwhp over the Mac's going to Kooks 1 3/4" .. both running catless y-pipes.

Don't have any pics. It has 3" oval piping on the drivers side going to round. Lots of ground clearance. The std Mac oryp is not that good. I can't tell the difference in sound between these and long tubes. The 3" y-pipe helps with rasp too.

Was this with the std Mac oryp?

This was with a flowmaster offroad y-pipe modified by someone in south jersey. Not too sure of the specifics wish I had more information for ya but I don't.

I think i have made a choice it will be KOOK's 1 3/4 to 1 7/8 stepped headers. So what do you think??

That's a very nice gain then. Was this on a H/C car? To bad the Kooks weren't available when I got my headers. I would get the stepped Kooks if I got new headers. Some cars have gained nothing peak going to LT's. I guess it depends on your setup.

the way i figure it is i'll be gaining hp all throughout the rpm range so it kind of a no lose chance except on my piggy bank

The 1 7/8 is over kill if you do not get new heads or cam. And if you put an X-pipe on there with some bullets, you will get that bottom end back from the LTs.

If you're really interested in the Kooks then give me a call and I'll hook you up!
