That exhaust looks great! Very creative and I'm sure it will be effective for both noise and performance! What cutout are you using?

Rallaster, when the electric cutout (it's actually just a 'valve' now) is closed, the exhaust is forced to flow through the 2.5" muffler. When it's open, it goes straight through the 3" pipe. I want the ability to quiet the exhaust down for neighborhood cruising, etc, but at the track/strip or whenever I feel like it, I want it to blow straight through for the least restriction possible (basically, you don't want any restriction after the turbo). The valve is infinitely adjustable so I can set it anywhere in between.

I wanted all of the exhaust to exit the tailpipes, none before, as a typically installed cutout does. The wastegate dump will also be routed back into the downpipe at a 45* angle.

Dave, out of curiosity, why did you paint it? It doesn't bother me and it looks good, but it doesn't need paint because it's SS.




Ah-ha! I like it. Thanks for the explanation! Looking good, man.

Making me wish I had the $$ to do the 2.0 Turbo swap from Fieroguy123, now. Getting really itchy for something with a little more oomph than my little dukey has.

Thanks. I can't wait to hear how this thing is going to sound!
It's a Race Ready cutout.

I pored though various forums trying to find out which was the most reliable, and this won out over QTP because of less reports of failure, and it has a lifetime warranty.

No problem, and thanks! It's so much fun seeing my visions pop into reality. The Haus of Guru is like my own real life Etch-a-Sketch. They're doing great!

Yeah, the 2.0 turbo should be a BLAST compared to the dukey (LOL). Patience, young padawan. Good things will come in time (that's what I keep trying to tell myself anyway. )

Steven,
I painted the exhaust to give it that final "touch". The muffler was polished stainless and the exhaust was unpolished. I wanted it to match. We taped off the flex pipe to give that the natural look. The wastegate pipe will be installed on Monday.

I've driven the 2.0T with the 3spd auto he has it mated with now, and it IS fun. When it goes in my car it's getting mated to an Isuzu 5spd. and it's getting a twin Throttle Body conversion to help reduce turbo lag..

Dave, okay. I think the paint will burn off in time, though, at least near the turbine. It does look very good in black.
I sent you an email.

Rallaster, cool. That should be a super-fun setup with the 5-speed. I'm not too familiar with that engine setup, how exactly will the twin TB's reduce lag over the single?


Here's one more pic of the exhaust. Before long we should have pics of it all installed.

The way it was explained to me is that it allows for a higher air flow into the intake and allows the turbo to spool up faster.

Wow, the stock TB must be tiny then!


I just came across a popular pic I've been meaning to save. I can see my turbo getting that hot on a hot open-track-day. When I first bought my AWD Talon it was stock, and one snowy day I went out to do AWD donuts. After a few minutes of spinning around and getting dizzy, we stopped because we smelled something a little funny. I popped the hood and we saw a red glow coming from underneath the exhaust mani heat shield. The manifold and turbine were glowing, and it was about 30 degrees out! That was only with the stock 11psi and 210hp.
I have good reason to be paranoid about heat and cracking with this one.

That looks familiar... On the way back from Fiero Fest last weekend my trunk carpet got melted and a foam pad I had packed away... I have to do something about the heat coming off the headers.
