Vargas Turbo Stage 2 / 3 update

Hey guys, hope you all had a great Christmas. Im supposed to be on vacation but I'm spending this time getting stage 3 done. Dp's are now done and fully tacked. Installed in car and with subframe all clears... Need to do charge pipes and water pipe / pump and will be ready to fire it. Before anyone says anything, no that is not the final orientation for the rear compressor housing. As for stage 2, got an email today. All parts I was waiting for EXCEPT flappers are shipping tomorrow. Take about 2-3 days to get them, then its wait on the flappers and assemble. So things are looking good. As always I appreciate your patience. Have a safe and blessed New Year.

Edit: Don't mind the multiple tacks all over the front DP. My fabricator is on vacation so I just fabbed it myself. My tacks are no where near as nice as his from the rear DP. But hey I got it done...

Looks awesome man, definitely appreciated!

Is that DP a full 4" or more?.... looks huge!

Would you also be making an option for a single exhaust? By that I mean not splitting into two 2.5" sections for the OEM exhaust. I'd think you could run a full 4" back to the mufflers and then split.

They are 3" and taper to 2.5" just like all aftermarket DP's do, they do look bigger in the pictures. We will not be offering a single option. It makes more sense to do it this way as it will work with 95% of peoples existing exhausts. It wouldn't be hard for people to make a twin outlet to single and run a single exhaust. If we get a lot of requests for it, we may consider offering one.

well would having a straight 3 inch pipe all the way back have a huge increase in flow or will it not matter? because I just feel as if the tape to 2.5 inch would restrict some airflow as it was meant more for the smaller stock twins.

if you made it 3 inch straight back i am sure there would be plenty of people who would want it that way if there were significant gains. cause all it would take is making a custom exhaust that is fully 3 inches back and if someone is investing this much money into turbos im sure they are willing to shell out an additional $1500 for a custom setup.

my turbo seals are leaking so it is time for me to upgrade turbos, also an excuse to upgrade lol because the leak isnt so bad. so if everything fires up and good to go when would you be selling these kits?

So the stage 3 DPs would hook up to the stock exhaust at the midpipes? That would be perfect because we could run our stock exhaust or almost any aftermarket exhaust.

One option that would be great....
For those that want to at least be somewhat compliant is catted downpipes.....
I know, I know, but without them you have a high probability of being totally screwed if you do this upgrade in Ca.

This set up is never intended to be smog legal in CA and we make no claims that it is, added catted DP's wouldn't change that fact, if someone is worried about emissions this is not the upgrade for you. To answer the exhaust questions there is no issues running 600+ hp through dual 3 to 2.5 inch Dp's keeping integration with most exhausts is important. If someone wants to go single they can.

I don't really get your question? Any off the shelf tune available now obviously won't take full advantage. The added tuning benefits of this kit will be all four O2's post turbo and factory vacuum actuated wastegates, all keeping the DME happy. Any good tuner will have no problems extracting power without jumping through hoops. It looks like we will be working with PTF to offer a tune with the kit.
