E Cutouts: worthwhile on a boosted GT?

[DocSean]

Will be running a procharger at 8 pounds with gt500 ab's and lethals off road H pipe. I know normally I wouldn't see big gains being the cats are literally bypassed, but would one expect any reasonable power gains on a boosted setup? Anyone currently running cutouts? Thanks in advance guys!

With the cats already off you kind of free'd up the biggest restriction....you may gain
A little but for the price of a good pair of cutouts that dont leak i couldnt justify it

Id be willing to say 15-20rwhp maybe more. Are Gt500 mufflers chambered? If so itll be worth it.

So on a roughly 600rwhp 5.0, what kind of gains will be yielded without the cats ?

i dont think you will see any gains, that would be worth it. I dont think ive ever seen a modular motor with electric cutouts make THAT much more power. it would just sound loud. and not the good kind of loud. Add more boost and a retune if you want more power. it would be cheaper than adding the cutouts and youd have more horsepower
