poll: true duals VS Ypipe & cat-back?.....
Hooker lt’s , custom Y pipe (no cats) , borla with (Corsa tips) = sound like A$$
That’s enough!! I am going to change my whole exhaust by next month and still don't know what to go with , a lot of members here r going with duals these days .I want my car to sound like mustang ...they have nice rumble
So what do you prefer and why? Vote plz

Moany will say "oooo get duals they are best" but this is just a myth from people who don't really know. And there does seem to be this ethos that duals - make a car.
Rubbish. Duals can be good, but they may not always be better and for other reason can be worse.
In performance terms it's all about flow rate. A good 3" Y setup is fine for most owners and larger 3.5" setups work even better. A Y pipe scavenges in a similar mannor as an X pipe so you get the same advantages. It's purly pipe diamter that is a restricting factor above certain bhp levels.
Duals are great and ultimatley a 3" dual setup has the best flow, but most Fbody's make no where near enough power to utilise it.
Duals are also an issue as there are few off the shelf kits, and most that are available dump before the axel, so they are VERY loud.
Custom setups are great if done well, but a poorly design system will have fitment and clearance issues along with the possibility of lower performance. So research it well.
Duals also can be a hinderance if you want to run an after market torque arm as it will limit your choice or you need to design the system with the torque arm in mind.
As for sound, well that's personal. The LS1 will NOT sound like an OHC Mustang. But it can still sound good, just a different type of sound.
Duals do sound GREAT, but really Y pipes don't sound bad either.
Check out the GTO clips on this website, it has duals and IMO is the best sounding LSx setup I've heard: http://www.stainlessworks.net/cart/m...da6d13de0410e3

I personally think a catback with cats sounds the best.
True duals make it sound like a race car, which is cool and red neck both at the same time. Sometimes they even remind me of a garabage truck, but hey...whatever floats your boat.
Edit: I fixed "read" neck. Note to self: "red neck" is a bad thing to mispell.

The difference is under the curve. Max power may be the same or very similer, but there will be a difference under the curve because proper duals with an X-pipe WILL scavenge better than a Y-pipe.
That said, you can go PLENTY fast with a proper Y-pipe.
That said, duals sound better.
i used to have a magnaflow catback on the car, but it was too raspy sounding for me.
while under the curve power is always better than just peak power, the duals dont make that much more power.
i think mine will be louder than TheBlurLS1
because i have cam ,lt's ,no cats and ST muffler's
I went with a catted Ypipe and catback just b/c I got tired of the drone of the 3" X pipe and the clearance problems.

The video doesnt do the sound justice, it was awesome. It's alot quieter now, but i still think it sounds great.
BTW - this video is hot off the press

I do not think there are anywhere near as many people who went back to a Y-pipe after trying duals as there are currently running duals. Perhaps a poll is in order, but I would be willing to bet that the VAST majority of dual owners keep them.
The lowest point on my duals is where the factory Y-pipe is crushed. If the duals are tucked up properly the ground clearance won't be any better with a Y-pipe.
If the drone is that bad the first thing to try is different mufflers, then taking them out the back.
