Wrong! And you are definitely NOT a genius. Do you even know the simple formula for an area of a circle?? Its pi*r^2.
Neglecting wall thickness, the flow area of 2 x 2.5" pipes is about 9.81 in^2. The flow area of 1 x 3.5" single pipe is about 9.62 in^2 (almost as much as 2 x 2.5". The flow area of a single 4" pipe is 12.56 in^2 (almost 30% more flow area than 2 x 2.5" pipes). Which means that a single 4" pipe will BY FAR outflow 2 x 2.5" pipes. I swear there are some serious dipshits in this thread.

Your last statement only applies to one person, look at the name next to your post for the answer.
With this point I will agree. To actually end this debate would require the budget the size of GM. I am really not that worried about which is better...just hate it when we have people on the forum who speak out of their *** about something they either know nothing about or worse think they do and are just too stupid to know it. Looking at the situation realistically, both can be made to perform so close to each other as to nullify the gains. What it really comes down to is sound and how much time and money someone is willing to put into an exhaust system.

And yea, it probably doesn't run mid 11's, its probably slower otherwise you would have an 11 second club (or better) under your username. My bet is you have no clue what it runs because you've never been to the track. What a waste of money.

How ironic that you call someone else out, when your entire post demonstrates that you have absolutely no knowledge on the subject of engine and exhaust flow characteristics.

Oh look at my title now I run 9's. Douchebag, get a clue. You are really entertaining, you should chime in more in the street racing forum here.

Well, sorry if simple math is far above what your tiny little brain can comprehend, but crossectional area DOES have alot to do with exhaust performance. Agreed, there are other variables, but that one is probably the most important one. If you think for one minute that an engine that requires more flow than a 2.5" dual can deliver won't perform better with a 4" y-pipe (two 3" pipe dumping into a well designed merge collector and then into a 4" single pipe, then a 4" cutout as in patricks setup) then you are smoking crack (or just uneducated). You simply need to go to school and study fluid mechanics. It would take a whole semester course to explain it and a bunch of prerequisites to even get to that course. In essence, 3 years of college and then you will finally "get it" There are other people in this thread that "get it" and obviously, you don't.

This guy is a complete tool. He's claiming he knows fluid mechanics, but he doesn't even understand that exhaust flow is completely different than the cross sectioned area of a pipe.

9 second club eh? FAT CHANCE. LOL.

You did trap 120 mph which tells me your probably spraying, but running 12s on a 150 shot, that simply is embarrassing. And your a mod also, obviously not a very credible one. Take your car to the track more often and study some fluid mechanics. Then we can all talk on the same level. But until then, I've got better things to do at the moment so,

Like 2+ years ago.On a stock motor with spray, yeah I ran it bad then, but that was when i first started using spray so take it for what its worth.
Now im built motor, head, cam, and an even bigger shot of spray and i can drive it a lot better.
Keep amusing me. What an ***.
If youre ever out my way please bring some $$ and whatever youre driving

And what edit was that?
And this is the whole problem, here. You are comparing some horribly made TD system that is not the norm to a well-made y-pipe system. How is that a level playing field? You're not being fair. The ENTIRE TIME, I have spoken of equally well-made systems, like the TSP kit and the Bassani kit. Both will make significant gains over any y-pipe and catback setup, as shown in the graph I posted.
I find it sad that you're trying to create an uneven argument - as in a bad X-system compared to a nearly perfect y-system.

Guess what: shorty headers will outperform longtubes if the longtubes have big cracks in them and crushed primaries. But well-made longtubes will outperform well-made shorties in every case, just like X-pipe TD's will outperform an equally well-made y-pipe system in every case.

As was said before, that was from 2005 you idiot. Also, you cant get the tag 9 secong club without proof.

Of course, this quote should give everyone else an insight into your knowledge of how to tell if a y-pipe is well designed.
I don't need the merge. He made one. There's no rasp so I know it's working well and I can send it back and save $50. The flanges or slip fits will leak, the welds will not. If I ever need to pull the tranny, he'll probably be the one doing it, so I'll worry about it then. Why cut up the exhaust now for no reason and cause leaks when there doesn't have to be any?
It's not a show car, so I guess the welds will be fine. Nothing will perform better than a weld, and since I'd have to cut it all up anyway to change it, I may as well not even worry.
