Cut outs

I installed a set right after the collectors on my 408. Kept them there for about a year, used them maybe twice. Ended up taking them off and giving to a buddy who's building a gasser. Really was a pointless endeavor and a waste of money. To me, I think they're a thing of the past, back before high flow cats and mufflers, I bet I didn't gain an HP over just running cherry bombs. My advice, save your money, save your time.
