True Duals vs y pipe setup
Had a offroad y with cutout setup and switched to TSP duals with Sweet Thunders. Would never go back. Sound inside the car cruising is actually better than the cutout.
As for being harassed by the cops, it's all in how you drive. If you are revving the crap out of your engine everywhere you go for the sole purpose of being loud, you'll get pulled over with a stock exhaust. I've never been hassled in two years of running dumped true duals with a cam.

I thought a lot of people liked the long tubes, ory and magnaflow setup? I guess I'll find out this summer because I'm going to get long tubes and I can't see getting rid of my magnaflow that I just got in the fall.
It is to quite this week i got rid of mine and went with full 3"piping and a dynomax bullet and a cut out, The bullet is deeper louder and 50000x better sounding than the magnaflow.....
After I said that I went to LS1sounds.com and pretty much decided that if I'm going to do it I might as well do the true duals because they sound so much better.
How are you guys with dumped duals passing saftey inspections? I know long tubes and no cats are illegal, but I thought it was illegal to have your exhaust dump under your car. I guess I could have false info, or all you guys know people to pass.

i have qtp headers and at the time the qtp non-catted y with daul cut outs into a catback---after a year n half the electric cutouts jammed up got stuck, my opinon it was **** a waste of money, fun to flip the switch,goin quiet to loud but i love the td set up and wont ever go back to a y-pipe and catback

not really....
Flow isnt really the issue. Its proper scavenging. A Y pipe is the best inductor hence when properly setup makes an excellent system. And when is dumps not a street system i run it... and so do... well hundreds of other cars...
Most people dont run duals out the back... hence they are lighter than a catback Y setup. Their not more expensive IF you are going to run a catback. They sound better than Crappy Y's because of the rasp associated with a bad merge. The Y pipe pictured does NOT suffer from that. My setup IS the one pictured and it sounds just like dual bullets.. Except mines a little deeper.
So.... Uhhh... What did you answer?

Hard to give a specific answer to the tired, general question: "Which is better?"
I made the question specific to be able to give a more definitive answer. Regardless, dumps are not a full length system - duals or Y, and not legal in CA and other places.
If you are able to run dumps and can put up with it, cool. The difference in power/efficiency between the two becomes reduced. Still, given good design, scavenging will not overcome 30-40% more flow potential. Sorry, just won't.
Your setup is nice and clearly well done, but I am certain it's loud, drones like hell, and not practical for many who have to deal with emmissions ***** or **** neighbors. I am also pretty certain it sounds bad ***.
Sorry you couldn't figure out what I answered...
he is not miss informed
i bet you i can make more power with a y pipe than with duals. Maybe only 1 or 2hp, but i bet i can do it with a good flowmaster merge with a 4" outlet.
This is one of mine. I bet you an x or h wil not scavenge like this. Both banks flow parrallel instead of colliding like an x.

Flow is absolutely the issue. It's the main part of the issue, though not the only part. Scavenging is the main part of the "art" I was referring to. There are too many variables but like I said - with two equally well designed, full length systems, duals will make more power and sound better every time. They will also be heavier and more expensive every time.

Flow potential? Hmmm well... You actually have to need the flow for "flow potential" to matter. And since a good 3in/4out Does flow what is needed the improved scavenging makes it better for Most street cars.
And im glad that you have figured out that in CA you arent allowed to run dumps. Well obviously you cant run dumps. So? You take the Y that was pictured and.... guess what... Run it out the back if you need to. Add cats if you need to. But this would be the same either way so not sure on your point here.
Its loud because we wanted it that way. Hence we ran a DYNOMAX BULLET. If you want it to be less loud....change the muffler.
Were not sayin that the EXACT y pictured is the end all be all of exhaust.
You could have a custom flowmaster Y with hi flow cats, a muffler of your choosing, ran out the back. Legal, hi flowing, Non-rasp,scavenging, no clearence issue Y pipe fun.
Sorry you couldnt put 1 and 1 together.......
P.S. Agreed on the term "better" when it comes to any car setup.
im thinking about putting TSP true duals and pacesetters LT ($900) or GMMG chambered exhaust ($900) for my DD 2002 trans am WS6 and i dont plan on taking it to the track any.. and i plan on putting a MS3 cam in after i get the exhaust.. which should i get
for a daily, id say neither. id get tired of the noise.
I think dumped TDs look awesome on Camaros. I don't make as much power as most of these guys, but for my situation a y-pipe set up works just fine. Also, I think my exhaust set up sounds pretty bad ***. I've seen some pretty god damn fast f-bodies rocking the y-pipe exhaust though without any issues.
does anyone have pictures of a true duals setup, with like a fake catback still on? I've got ARH 1 3/4 headers and their 3" ORY, and a magnaflow catback. what I want to do is get true duals, but keep my magnaflow exhaust on for looks.. not connected to the true duals at all.. is this possible?

im not sure why youd want to leave it on the car for looks?
to me its dead weight and cheesy.
id prolly laugh at someone if i saw that at a cruise night or at the track.
