Cut-outs

OIC - well, I used Warlock race mufflers so the cut outs are already there - If you plan to race it and open headers are allowed, I would suggest doing it - everything I have ever read on the subject suggests you'll gain a tenth or two of ET and a faster speed running open headers.. I will say that I personally do not have any practical experience on the subject as the only open headers I have ever run were on a 78 Trailduster - but I love the sound of open headers!!
