Thats decent numbers for stock. 3" Catback will probably give you a good 10whp more.

they are pretty good numbers for stock i dynoed at 193hp and 191tq when i was stock. one thing to always remember be able to support the horsepower b4 you make it.

seems reasonable. the exhaust is probably robbing you of a lot of power. ide be willing to bet a 10hp gain with a mandrel bent 3" exhaust...

I was expecting 200, but i guess 192 is pretty close. its probably the exhaust thats killing the 200

You know, you may be right. Going from a 3" down to a 2.5" catalyst and a crushed exhaust may be enough backpressure slow those last few hps down. The only problem is finding a 3" exhaust that looks stock, (2 medium pipes) and that also sounds close to stock. While at the same time not sacrificing performance.

Yes, I have not put on my walbro fuel pump yet, therefore I have not put on a manual boost controller, which then leads to a FMIC and then that leads to bigger injectors, which then leads to a better exh mani...etc etc...SO i kind of wanted to make a run, catalog it> throw some upgrades>make a nother run..etc

Those are pretty good #'s for stock. How much boost were you running b/c that means alot too. I'm guessing you were around 8ish 9ish psi?

you dont need an after market exhaust mani, they dont make that much of anything but bling. just because you have an after market fuel pump doesnt mean you have to upgrade everything els, you shoulda put the fuel pump on already with the swap.

Have you look at the Circuit Sports exhaust?I'm not sure how it sounds, but it attempts to retain the stock look. It is stainless steel and 3". Worth checking out and several sponsors carry it.

who told u a after market exhaust manifold doesnt do anything but bling athat is not true at all. if you get a bigger turbo a exhuast manifold will help alot in turbo spool time/lag.

While this is true, unless you get the cheaper manifolds (like a Megan) I would recommend extrude honing your stock mani. It gives you the same benefits and shouldn't cost too much. Talk to WDracing for a how-to. He'd be willing to help with that. I'd go with the exhaust and a turbo elbow upgrade before I worried about the exh mani.
