4" down pipe???

[lociman]

so i have a 2000 dodge with a stock turbo and i was looking into a 4" down pipe but lookin in there at the turbo outlet looks like it is the stock 3" so what good will a 4" pipe do when u are still only push out a 3" outlet just woundering if it helps or if it just sounds really cool

You can get a larger elbow for the exit on the turbo, but the larger pipe helps open things up and flow better. To get a complete 4" exhaust an upgraded turbo(S300 or hx40) and hx40 downpipe is the best way.

Yes, the turbine outlet is only 3"...and yes a 4" dp will help if going with a 4"exhaust".
Just be sure if you buy a 4" dp to tell whoever that it is for a stock turbo so they can get you the right size for the inlet.

pac brake & banks sell a 4" elbow. Dieseltracks your sig shows tst/van aaken stacked, hows that working? I thought van aaken was timing & fuel, I'm interested in what kind of hp your seeing, Op sorry for the hijack

[dieseltracks]

The VA is timing only...it adds some fuel but only what it can through the can-bus (data link) connector via the computer (doesn't tap the pump wire).
Some VA's had a toggle switch that allows you to run a timing only setting or timing+fuel setting. Mine has the toggle switch...I like it just for that reason...I can run it either way depending on my mood.
I usually just run the VA on timing only and use the TST to add fuel...seems to get better MPG that way.
I dyno'd a little over 400 the last time...but I've had some IP issues for about 2 yrs. now...it runs so I don't mess with it.

Thanks for the info, I dont have my VA switched, I'm going to checkout that option
