Redneck, do you even know what scavenging is? Reason I ask is because all this talk about physics sounds crazy to me.
You ever noticed that an aftermarket race exhaust for a bike will convert a bike that came with dual pipes to a single? There is a reason.
As long as the total area size of the pipes is the same between a dual and y pipe setup there is no reason the dual should make more power. Now that is closer to physics.

I guess they should go speak to Redneck and get some advice because their championship winning setups don't comply with physics.

Still wrong, unless running high bhp. a 3.5" Y setup will flow very similar cfm as a 2.5" dual setup can.
Please STOP making things up - you have no idea!!!!!
NO no no no no. An X scavenge's very similar to a Y and differently to a H not necessarily better.
Yes but the aim is to have a setup which flow sufficently for the desired bhp level and does not exceed it.
Really!!!!
Once again 8 cylinders compared to 4. A 3" Y setup will probably have a higher velocity than a 2.5" dual setup because it actually has a lower flow rate.
Strange then how you seem to have little clue about it
Lots of people it's called physics.
Spot on. Many racing cars (GT, circuit, rally) that use a V engine run a Y setup. LG, the guys who make arguably the best aftermarkey headers for Corvettes. Their own race cars run a midified version of their own LT's and mid pipe - guess what they convert the off the shlef X to a Y pipe.

Your such a goof! Your posts are not only annoying, but untrue. Please apply your misconstrued book knowledge elsewhere.

Plus it all makes logical sense too. It just some people get caught in to the believe that because one or two people have gone from an AVERAGE Y setup to a GOOD dual setup and seen gains it must be because duals are superior. But that's doesn't makes sense IMO and is just an inaccurate conclusion.
For the record, my 10 second Naturally Aspirated 346 runs 10's through a catback.
With that said, If you have to resort to to personal attacks, you've already lost the arguement
Now for the Moderating part:

Take this as the first warning.
Personal attacks will not be tollerated here.
If you can't keep your posts to techinical information and resort to calling names, etc, you need to find another place to post.

I had to sit and think about this for a while. I ultimately went with ORY/Catback because:
1. Clearence issues (its not my daily driver, but I live in very hilly areas)
2. Tips look damn cool
3. I don't want the fumes coming up into my car making me stink, I want the fumes coming out the back of the car making the people behind me stink
Either way, that was just my decision/opinion.

I have got a custom 2.5" TD system with dynomax bullet mufflers and it sounds great. I didn't really feel any difference with power because it got opened up so much, but this exhaust system will be sufficient for about as much power as I can get it. With you already having a stroker, you will more than likely get more power out of it than I did, but if you plan on doing more work and more power, TD's is definately the way to go.
