Can i run a vf34 with stock up/dp ?

i dont think so. you might be able to for a lil bit but i wouldnt.

Why not go for up/dp first, better yet, with Cat-back to complete your exhaust system. IMO, it's better to have those things first, then have the turbo.

Yes, You can run it with stock but you will need a very conservitive tune, almost like stock. Ide recomend getting at least an up-pipe before you do turbo.

the up pipe cat might break. then your be in a world of ****.

I wouldn't run one with the stock dp either because the wastegate will be blocked. Best get a nice bellmouth or divorced dp so the gases can flow quicker.

yes, any catless OR high flow cat will do the trick.

^x100.:D

Does anyone know how the vf34 will do on a 4EAT. (mainly lag) Right now I have a Vishnu UP and a Helix DP with Hiflow Cat and Greddy EVO Catback. Running COBB AP Stage 2. Also if it makes a difference, Samco IC and MAF hoses and silencer removal.

It will do fine, AVE here on iclub has a vf34 with an auto.

Good to hear. Got to start saving up just as soon as I get my new struts installed. About two weeks out.

I disagree. While you will not gain much power, you can run VF34 with stock up/downpipes. I don't see why you would do it, but you will make some power. Of course, you will need to get your car retuned.

make sure you buy a bellmouth downpipe with that 34. i would recomend the up and down first though
