Ok so this may be dumb but i cant find any solid answers. Im doing cutouts on my Dad mobile and i want cutouts for those cool dad points. Just cant decide if dual or single. If i go dual im going to do it right after the header before the y pipe if i go single i will do 1 after the y pipe. My question is, are the sounds different? I have a cam and open headers right now and i love the chop it has. I do not wana lose it. So my guess is, if i keep duals it will sound like it does now but what if i do single? Will it change the sound? The only thing pushing me away from duals is the price...ouch 400 green ones for just a sound preference is kinda dumb so thats why i would go single but i wana keep the chop the exact same. The dad truck needs help. I can upload a video if you wana hear it.

I wanted to merge at the y pipe and have it routed the same way stock is routed. I dont like duals on suvs but thats just my taste. I just dont want to "muffle" the chop out of the cutouts

I have a single cutout after the Y merge on my silverado. It still had plenty of chop!
Reason im asking is because ive read a bit about true dual exhaust and all that jazz and that it changes the sound because the exhaust pulses merge and bounce off eachother and i figured the same concept would apply to the cutouts. 2 vs 1 and all that. I have a stage 2 truck cam and the reason i got it was because of low end torque and the notorious "choppy cam" sound so having the cutouts work against that bugs me lol idk im just being picky i guess lol
Yeah im leaning towards doing the same i just gata figure out what size to go with. I have headers with 3 in collectors y pipe is gana be 3in and 3.5 or 4 out and finding a cutout for after the y pipe that size is gana be hard maybe

I have a 4" from QTP that I will be putting on soon upgrading from the current QTP 3". I think they even make a 3.5". Ive had the 3"QTP for 3 almost 4 years now without a single issue.

What's the benefit of an exhaust cut-out, besides being loud?

Depends on where you place them. Absolutely no restriction from cats, mufflers or long pipes with lots of bends.

Thought a certain amount of back pressure was good?
I've heard to big/free flowing of an exhaust moves the powerband higher. Basically less torque but more hp

Its not so much a performance mod, yeah it frees up a little pony or two but not much. Its more for fun and showoff kinda thing. Gives your truck a "split personality" so to speak. Im going to be running 50 series flowmaster. They are made for mid tone not much above a stock sound. That way i dont make the kids go deaf but cutouts for when im alone di**ing around lol. Its the dad mobile after all lol

For more stock like engines yeah there are a ton of theories on back pressure. For anything that's being force fed boost I would say less restriction is better.

Do you have any videos or sound clips of it?
Yes i do have one of when it was running, i mean it still runs but its passing oil thru ring in cylinder 8. So right now its at the shop being "upgraded" with a TSP forged rotating assembly but its been delayed with the whole "rona" shit. BUUUUT yes the video shows of when i first got it running after all the upgrades except for the TSP parts. Needs to be tuned so im assuming it will quiet down a bit and thats why im so cautious about the cutouts. I love the sound its making now so im trying to keep as much of it as possible. Here is the video...

Sounds great!!!
Thanks, i know it will tone down the chopiness after i tune it, its probably runing really rich but hopefully not too much. I also hope the single cutout doesnt change the sound. Thats why i made the post to see if anyone had experienced any difference. Hopefully it will be up and running soon again lol.
