HP gains from MAC's What kind of HP gains can I expect from MAC headers and an ORP on a 98 Z28 6-speed? Is there a problem with buying used headers? A friend will give the headers and y pipe to me for $350.

Re: HP gains from MAC's You can realistically expect about 15rwhp. I do recommend porting the primaries and having a Flowmaster collector welded in to maximize the gains.

Re: HP gains from MAC's these days hookers can be had for a low price.
New macs are only $450 so $350 still seems high.
Macs also have a bad rasp!
See if that price an come down

Re: HP gains from MAC's you can buy the MAC's off of Thunder Racing for $350 for the headers without the ypipe.
