High velocity header collectors, are they worth it?

gmonde,

Did you have the extentions on when you put the step headers on ?
Also, how long were they ? Thanks, for your input .....

We run Mark's Merged collectors on all our stockers! On our low torque/HP cars they make a very nice improvement(.03 to 04) in our 60 ft times. If we could afford them we would have his headers on our cars...just not in our current budget. We run a production Hooker or TTI header....13/4 on small block mopar and 17/8 on big block ...usually buy different used one's from swap meet to try. These collectors were best money we have spent on our cars in terms of improvement per $$.

Dave, go to Larry Meaux's site www.maxracesoftware.com and get his PipeMax software. While you're at it, get on the list for his ET software. The PipeMax software is some of the best header software there is, it has some pretty good dyno simulation software built in, and it is affordable. The software comes with tech support and a membership to his tech support forum.

when first done i just had a short collector(cone) car sounded very responsive but didnt seam to have torque (60 foot wasnt there) removed the short cone and installed a longer tapered 10 " cone that opened to three inch and used the short cone removed and installed on the end coned back to 2 5/8 ,,,the car had its best 60' at the divisional in july,with not the best air conditions
but that is my combo,,i do a lot of asking of racers what they are running and there are so many different senarios for the same cubic inch ,,,gmonde
