I'm curious as to why you guys call it, "true duals" when it is not...... As soon as an "X" pipe is added, it is'nt true duals and never will be.... TRUE duals, is one pipe per bank and NO sharing ... Always was.. Totally different sound too..

i love mine
I love my true duals 3". If you are not planing forced indution of any kind aka turbo or no2. 2.5 in pipe will flow more than enough for a stock ls1. I have hooker long tubes and 3" true duals with a h pipe and two dynomax ultra flo mufflers. I don't like the way the bullets sound the ultra flo sound so much better deeper tone. And I have 3.5" hooker tips sounds awsome and it gave me all kinds of power.
But my ls1 is in a 95 silverado so I have a lot more room under my truck than u guys do.

So somewhere along the line when people started adding a real dual exhaust system the term somehow started as "true duals"
I really shouldn't have to explain that,,,right??
As far as the X-pipe/H-pipe comment, I don't understand where you are going with that. H-pipes have been around since the 60's, Ford was using them as OEM equipment back then. They realized the benefit long before the other manufactures as far as I'm aware.

Ya we had a 71 Nova that was strictly a back halved drag car years ago, open headers always.
Anymore I'm a street car guy that does double duty, I'm more into keeping the car quiet and as stock looking as possible, but still going fast. To do that and get the most out of any dual exhaust system requires an X-pipe. You give up ET without it. H-pipes work okay, but not as effective. Since Pure Stock and FAST allowed the X-pipe in the rules a few years back it's what everyone went to.

But the X-pipe was found to work more efficiently at both equalizing and scavenging, so I went that route on 2 other cars.
I have some track and dyno testing around here somewhere, showing how the H-pipe helped to increase low and mid range torque, and actually picked up slight ET on this particular car. If I remember right the X-pipe helped higher in the rpm range.
To get more in depth, if you talk with Dr. Gas, they make X pipes specifically for particular engine/tranny combinations by manipulating the size and the shape of the opening inside the X-pipe. I had them make one for my chevelle a few years back. Did the same thing on my fathers 69 Goat, rather than just buying a generic X pipe "one size fits all" type of thing.

I have not seen anything on the Kooks dual set up. Anyone have feedback and any thoughts on hooking that system cat back as I do not have long tubes.
