cutout outs good or bad?
I am looking to get cutouts put on my 99 z28, as far as exhaust goes i only have borla catback, I am not sure if i have headers or not? (i know sounds dumb i should know if I do). I am aiming for a daily driver and to make decent power. would the cutouts be a good investment? any info on what i will have to do or replace to fit the cutouts on would be appreciated.
also i love the sound of my exhaust will this affect the sound, such as leaking cutouts?

Cutouts are a popular cheap mod, but realistically has been shown just to gain a handful of hp. Not worth the trouble imo.
Better to save your money for a very good exhaust system.
A 2.5" True Dual system out the back with or without headers will put a smile on your face all the time and will perform better than any cutout.

You drive a lot. Most who drive a lot prefer a cutout. That way you can let the exhaust flow through the muffler while driving, and you can open the cutout when you want extra power. Depending on your setup, it could make as much as a 15hp difference. I've seen it on the dyno in person. But that was a max effort setup with heads and a T-rex.

You don't need a true dual system. The gains from a true dual system going through two mufflers instead of a Ypipe going through no muffler will be very small if any. Not to mention scraping on every speed bump around...
Go with an eletric cutout. I like my McCord. $117 Best of both worlds. Quiet(er) when closed. Loud as hell open.

it all depends on what you want, I got a magnaflow b/c I wanted an aggressive sound without being EXTREAMLY load and reaspy another good one is hooker, but if you want it loud as hell either get a cutout, LM, or just dont have a catback

you need backpresure. during the installation of my supermaxx LT, cats and y-pipe system, i drove about 50 miles with just the LTs and cats. sure it was nice and loud, but the car lost a tremendous amount of HP. i'd say about 30rwhp! from what i started with. after i got everything bolted together, the power felt great!!! if you're unhappy with your aftermarket full exhaust system, then i suggest get a true dual system.

A cutout was one of the first mods I ever did. I never put it on a dyno, but you could FEEL the difference... the car was very noticeably different with the cutout open. That's when I took the cap off and never looked back. It is NOT a waste of time or money, especially for the price.

Pacesetters --> ORY --> Cutout --> Magnaflow muffler welded in place of stock
I really like the sound mine has.

I agree, the power from true duals is nice, but IMHO not worth the constant noise that you get. That's the only reason that I went ORY instead of true duals. If not for that awful noise and the way that it makes everything rattle in the car, I'd have true duals as well. I just can't see driving the car 2hrs from home (each direction) and having that constant loud LS1 sound in my ears.

Cutouts are supposed to be used to scare women and children with your LOUD exhaust. Any performance gains are minimal, so keep things in perspective. Cutouts are a great, cheap way for an otherwise quiet car to set off car alarms and make ricers poop their pants at the touch of a button. Just make sure they are legal in your state, or you may need to buy a mechanic a 30 pack of lites to get it inspected.

I gained about .25 sec and about 3 mph at the track (1/4 mile) with my cutout open. I have a stock muffler and catback pipe going to it, with Pacsetter long tubes, and pacsetter offroad Y-Pipe. See sig for other mods.

There is absolutely NO drone, annoying loudness, or rasp. It's clean and quiet as factory.
You're thinking of TSP's dumped duals, which are annoying as hell. Or dual systems with bullet mufflers, which are loud as hell also.
The Bassani system (or a custom one using the same dual-in dual-out full size muffler configuration) is refined which is why it costs more than most catbacks. But's it's stainless steel and will outperm and outlast the life of the car.
Just think of all the Vettes that are running around with True Duals with full size mufflers, do you think those are bad too?
