You mean headers suchas 41005 ,41001 incomparison to 41021 and like round headers ?


More low end torque from 41021 or ) round headers , nice free reving engine that is fairly responsiveto throttle input .

The 41005 , 41001 or ] double bend headers tend to smooth low end throttle response a bit but IMO create a more smooth climb to the peak rpm . Feels like they also create more rpm in most cases

Ali , I run 1/2 gallon of byrons 30/11 race 3000 through the engines and I do it in an actual car , not a big fan of break in benches

9901 and 2084 are two totally different pipes , totally

I personally don't really like 9853 or 2084 in buggy , too much low end torque , I didn't use to like 9901 either but found it to be a bada$$ buggy pipe when used in conjuction with some other stuff . In your case , running on a super grooved track , u might be able to utilize a little extra torque down there .
