x2 Hey Ron what do you mean spaces the headers with washers over the flow masters?..............Yes please explain this?




Yes just as was said right where the 3 collector bolts bolt the collector to the header. Just take the bolts out and spread the header and collector apart and put the bolts back in with some washers in the gap on the bolts. Many guys around here did it years ago for the sound but I prefer a closed exh sound myself. But we did it with his car do see how much it slowed as we knew it had gone faster with open headers and it ran just as fast (11.40's) like this then it did with open headers. And this way you dont have to remove or hang the exh pipes out of the way. Ron


Hmm.....learn something new every day,never herd this b4....

Tucson AZ,
FWIW, Car picked up a little over .05 today with the exhaust cut outs opened up. That was with no change of jetting. I guess I'll have to see about some exhaust modifications to free up some more power in street trim.
