im definetely a believer in the cutout now ran with it closed than ran again same temp everything went .23 quicker with it open
it was loud as hell in the truck but my buddy standing at the back of me when i took off said he could barely tell the diference,ive got the quick time performance electric cutoutI bet you it sounded SICK!!! I need to do this mod... what kind of cutout, electric or manual? How much do they run?
I've never seen a cutout help any if it's after the stock cats. Actually makes it slower, the backpressure of the exhaust helps build some torque.
Now IF you add long tube headers and cutouts, then yeah it'll help.
:iamwithstupid:lol....then you've never put one on a 4th gen f-body or these trucks, or countless other vehicles apparently. In similar weather conditions, it's been proven over and over that a cutout is worth a a good tenth and half to 2 tenths, and about the same mph over a STOCK catback, and that's with the cutout after the cats.
