Well...

I was planning future mods and this is what I have right now, AEM intake, Grounding Kit, Borla TD Exhaust, UR Ultra SS Pullies. Going to come...GReddy Twin Turbo, Fujitsubo Front (Y) Pipe, and a Jim Wolf Technology (JWT) Flywheel.

After that my car is still 100% street legal. I was deciding between the last too mods. If I put in one or the other will my car not pass emisions and not be street legal anymore, LSDunique Test Pipes and Borla Header. If I put in a header will I pass emisions or not? I am pretty sure if I put in testpipes I won't pass. Right? Thanks for any help.

headers are legal, cat pipes aren't, but it wouldnt take more than an hour to switch the cats back in before emissions test if you decide to use them.

test pipes no. but in texas headers turbo flywheel. you name it as long as it does not throw the CEL

Sillent Killer

People are telling me that the test pipes are not throwing CEL's anymore. That is why I am interested. Plus there is an instant 15 RWHP gain.

One thing that interests me on your future mods is the fact that you are doing all this exhaust work before the twin turbo. Really, I would look to make sure my exhaust choice matched my turbo future for diameters, backpressure, and such for the exhaust system.

if they do emissions test, then even w/o CEL you won't pass, since they check the exhaust gases, unless you bring it to a sloppy shop.

see in dallas all they do is hook up the obd II meter. i have never had the sniffer hook up

Another thing I am conserned with is sound. I know the Borla TD and the AEM intake sound good. Not too loud. If I add a header is the sound cgoing to increase a lot and the sound quality drop? How about with test pipes?

test pipes have a significant gain in sound/noise.

Sillent Killer

How about headers?

SlamMan

Headers won't change sound much at all.

Sounds like your putting an awfull lot of money into things that will have to come off with the addition of the turbo. Especially headers and cat-back. Headers you won't be able to use, the other you would be better off with a 3" straight through turbo exhaust. I don't think the Borola is straight through or 3". Correct me if I'm wrong. Is the plan just to sell this stuff on eBay?

Sillent Killer

Thanks for warning me ahead of time. I forgot.

In that case...Can I add pulleys, flywheel, Fujitsubo Front (Y) Pipe, and test pipes? Which of these can be used with a turbo and which ones can't?

little_rod

See, this is what I told you earlier. No reason to do all of this exhaust work before you get the turbo cause some of it will likely be changed anyway. Hey, my opinon my differ from others, but I would almost leave any engine work alone til I get the turbos. Now with an SC, do all the exhaust work you want. But turbos are different. Just a waste of money to me. IF you have to spend money, go ahead and get better rods or pistons for your turbo setup.

Sillent Killer

That is pretty expensive. I don't want to spend that much money. I am aiming for 400 RWHP.

Intake and Exhaust will put me at an extra 20-25 RWHP. Pullies will be an 10 RWHP. Y-Pipe will be 5 RWHP. The GReddy Turbo makes 345 RWHP at .45 bar. If I put test pipes that is an extra 15 RWHP. This brings me up to near 400 RWHP.

Sillent Killer

I have another question. Who makes a good exhaust that can be used with a turbo.

little_rod

Well, dude, it is all what you want. You have to remember, this ain't gran turismo, those hp numbers don't add up like a video game. We can all come up with what exhausts we think would be good with turbos, but right now, I don't know if there is one on the market that is "turbo ready", although you can run whatever exhaust you want with them.

I would advise for you to do some searches on this site and others to get a general idea of what is out there and what you want. Cause if you don't, then things can get more expensive than you can imagine right now. Just my $0.02.

Sillent Killer

Those are approximate numbers.

crustydemon

Is the Y pipe something other than what I think it is? How is that used with dual exhaust?

Sillent Killer

This Y-Pipe replaces the stock Y-Pipe with larger diameter tubes so there is a 5 RWHP Gain.

Sillent Killer

Does anyone know anybody who sells test pipes with high flow cats in them. Any brand would be nice. I haven't found any.
