Default Cutouts or no cutouts

I have a 416ci stroker making 502/492. I have kooks 1 3/4" headers through a magnaflow 2.5" catback that has off road pipes for the track.

Would I benefit from cutouts or should I not waste my time? Bear in mind I do not care about the scare factor or the loud sound. I would only do it for hp/tq #s.

My thought is that if I don't get atleast 10hp/10tq out of it that it isn't worth my time.

What is everyone's thoughts?

There is no guarantee but if you have 2.5 in. exhaust all the way out the back...you could gain more than 10/10.

it really depends on how free flowing your ex is.

My TA made 12RWHP 11RWTQ running single 3in e-cutout vs through B&B Triflo

I say do it for fun factor(opening it up at cruise ins)

Id say you may benefit a little more due to you having more cubes, i'd say 15rwhp
