probably the wrong forum section for that question.

cutouts are a great, inexpensive way to increase HP @ WOT

How much would guess it increased by? And does it improve mpg to have them open or closed? And faster with them open or
Closed?

to be honest.... It's not enough for you to ever notice a difference. I wouldn't even think about it.

Wow really? I always thought cutouts were the answer to max HP in the exhaust segment by bypassing the cats and mufflers. When the cutouts were closed, was it flowing through the precats, cats, and mufflers?

2010 Camaro SS modified extensively. I stretched the body to make it a 4 door, but I swapped in the 3.6L DI V6 for fuel economy. Then I picked up a corvette body around the V8. I also swapped the body for a C2 Z28. (In short I traded it for three cars, a Corvette Z06r, a C2 Camaro Z28, and a Cadillac CTS Summer Performance package 3.6L DI with Aisin 6spd.)

I installed a manual cutout on mine and honestly, I lost horsepower and some torque. When I leave it closed up though, I gain horsepower and keep my torque. Without enough back-pressure you'll lose power.

Yeah but it should increase more than 1HP shouldn't it? I mean it sounds amazing don't get me wrong, that's the reason I bought them if I wanted performance I would have bought the V8.

What can I do too increase my horsepower thats also pretty cheap? Just want a little bit of an edge over other stock V6 camaros

It depends where you put the cut outs. Darth Emma has hers right behind her headers and she picks up like ~40 rwhp when they're open.

It depends where you put them. The closer they are to the headers the more you will pick up.

There's more to it than just a definitive yes or no. For example, it depends on how restrictive your exhaust currently is. It depends on where you put the cutouts. Depending on where you put the cutout(s), whether you have high-flow cats or no cats at all, etc etc etc.

That said - I know a guy on my website with a 4th gen Trans Am who had the stock catback exhaust but swapped in an LS3 with cutouts right off of his long tube headers. He gained 40rwhp opening his electric cutouts. This was a back to back run on the dyno - one pull with them closed, the next pull was with them open.

On the other hand, I have a 357ci LT1 cammed, long tube headers, no cats, and a v6 2.25" MagnaFlow catback exhaust. I have a 3" cutout in my intermediate pipe right before it bends up and goes over my axle into the muffler. I only gained 4hp opening my cutout.
