Default 4" Cutout?

Also, i have LTs, O/R Y and 4" Catback. Will i see any gains at all with the cutout open? Probably not, but i will really just be doing it for when i want to be loud

link didn't work

depending on your muffler you may or may not see HP gains, but the sound is wicked

I see 1HP open v's closed with my 4" system using a Magnaflow race muffler.

I use a DynoMax 4" cutout and DMH 4" E- setup.

Would that make you lose power from no back flow?

back pressure is a myth. Less backpressure=more horsepower
