Racers like to acid dip the headers in the pro series in order to make it as thin as possible. Thin headers to them are "good headers". The thick tubing you would want for durability on the street would be "bad tubing" to a drag racer.
If you listen to the harmonics of the big tube headers on a Boss 302 at distance the tone is lower, more bass, then the Windsors.
I think that is bad. It is showing me that power is being lost through the system.
2-1/8 is too big for them. 2" is about right.
On a Cleveland 2" on the street is about right with a 3-1/2" collector. The problem is getting the pipe lengths correct.
The only way I can see all of the exhaust tuning size vs. length working in the Pantera is with a 180 system. Then that system tends to get restrictive over a certain rpm range. Certainly it's done at 8000 rpm while a big tube normal set of headers is still going.
What am I saying? I don't know? Do you know of anyone that can harmonically tune a big Church organ? Introduce him to a header builder. At least if it doesn't make power it will sound good! Tell them you want to make the car sound like an Indy car or one of those "crazy bikes" that crank out 14,000rpm. No wait...don't do that. I did and those guys got together and beat the crap our of me. Don't go that way.
Dam. Now were back to square one. I must need more coffee or another Martini or something. Gobble, gobble. Later...
