Gen 5 Camaro External Bolt-On Tech - Cutouts worth it on bolt-on cars?

Hey guys, woundering if anyone has tried or seen any testing with cutouts and bolt-ons. I was thinking about running dumps after my H right before the rearend to see if it picks any. On my old car I ran the same setup and it was worth almost .2! That was a cammed BB though.

Some cars it helps and some it dont but it sounds good !!!!!!!

I gained 0 hp going from my full TSP exhaust to open X pipe on the dyno in a 500whp cammed car. No restriction there

Really wow... thats pretty good! I am running full 2.5 exhaust though, you think that matters?

I bought cut outs mainly for the sound.
