Cutout WOT noise
Hey guys, I just got my cutout installed when I have it open for some reason under WOT every time it redlines and as soon as it shifts (a4) I get a loud BRAP/pop/backfire type noise. It does not do in when I rev it up in neutral, or any other time. The noise does not happen with my stock exhaust when i close the cutout so I dont think its a missfire or anything. Anyone know what this annoying *** noise is? Heatsheild getting hit with a sudden blast of exhaust maybe? I don't hear it in any LS1 WOT cutout videos. Any input would be great, maybe this is just something normal as a lack of backpressure.

mine did it. Never hurt anything i dont think. Periodically, like once a month or two months, it would let out a very loud blast through the cutout, i dont know if that **** was normal, but pops during shifting or coasting arent that abnormal for a cutout, especially if your tune isnt spot on.

Nah my trans is def not slipping, its an exhaust noise and it does not happen when i have the cutout closed. Plus I only have 30,000 miles on my car haha. I think its because right as it shifts, there is a temporary lack of backpressure and it makes that noise or something.
