The stock replacement one is the same design as megan but with bracket welded on to prevent cracking. Not worth the $500 if you ask me. The t3 version is good for someone building a custom kit.

just wondering what did your car do "stock" on a DLL?

That's a good one, they need a proof reader. It EXPREME and is for a 4A63, I sure hope it works on your 4G63. Doesn't look to impressive.

I just found this thread after looking for info on the Megan manifold I just picked up in a package deal. Seems as if there is a lot of spinning of wheels without a lot of traction going on... I do know that I trust David in that he puts results ahead of everything else. I also know I have not seen him solidly endorse the Megan I just bought so I'll have to consider if I will use it or simply find it another home.

That was from 6 different cars that were tuned by my friend on the laptop. My car on the DLL made 372. Matched my graph up to many other and saw how mine didn't taper as bad and was making more power till redline. With similar mods I do believe the borla manifold is why I am making the power I am. The manifold has a good design and I have no idea why the manifold isn't more popular. I am sorry I don't own my own dyno David but since I am the only who is logging this manifold I have the right to claim the power results. You cannot just go about saying all manifolds suck but yours is the one to go with. I know you have dyno tested your manifold but don't go about and ridicule people for providing results that you haven't tested yourself. If you want to do the test I have no problem sending my manifold out.
Correct me if I'm taking this out of context, but is this your support for stating the Borla makes more power? Cars with similar mods using different manifolds tuned via the DLL? Or did you actually change out each manifold and then tune with the DLL on the same car?

Just trying to clarify your support data.

I did 3 back to back tests. First I had on the ported and coated manifold, then the borla, and then megan. I ended up sticking the borla back on. I don't own a dyno so all I have to use is the DLL. I have also compared the graphs to other cars with same mods and I can clearly tell where the borla outperforms a ported and coated stocker and a megan. Which we all know those 2 are the most common used. PM me if you want the log comparisons.

Hey, I haven't found much info onteh Gtspec manifold so I figured I would ask here. Does anyone run this manifold and have had any issues with it?

The GTspec is like megan but with thicker piping. You will make the same power as a ported stocker.

So the Gtspec manifolds have been cracked before? So which tubular manifold yeilded a better power curve?
