WSP's 3" exhaust
I know that Matt has it, but does anyone else here have it? I'm going to upgrade to 3" in the spring, and was considering attempting to build my own, but now I'm leaning toward just purchasing theirs for simplicity.

I was thinking along the same lines, but I'm wondering if it is better for supercharged people to stay with a 2.5" system, since we will need 3" only at high rpm, and the tradeoff in low-mid range power might hurt us more than the high rpm gain. The turbo guys don't have to worry about that so much since they're at full boost much earlier in the rpm range. Plus just about everything I've read says that 3" is overkill for our engine size and power range. But I know Matt had significant gains with his. Of course that was boosting with nitrous.

In my mind, bigger is better. I (and I'm sure just about all us SC guys) have a hard enough time keeping the tires planted in 1st and 2nd gear. Yes, I'd loose power down low, but how often are you at 2 or 3k RPM and flooring it with traction? Not often...when (drag) racing you're landing much above that on each shift.
That seem reasonable?

Yep. That's how I look at it.
I bought on_alert's 3" system - installing it in a few weeks - I will report any Dyno differences since i will be Dynoing between now and then and not changing anything after that but the 3" Exhaust.

I had mine built at a local mandrel bending machine shop here in the ATL. They are called Grand Muffler. They did from the Cat-back, all aluminized piping. It is all one solid piece of piping, except for the flange before the axle. I didn't realize til the other day that it was one solid piece, no welds. It looks amazing. How much is WSP's 3" system anyways?
I gave them a 3" muffler to use and a 3" cat, they did the rest. Everything installed and done for $275.00. Not to bad eh?

I noticed they offer a muffler option, how does it sound with the dynomax which is the quiter muffler? A 3" exhaust would be cool, but hopefully it's not annoyingly loud at idle. Is it a nice deep tone at WOT, like the 350Z? I just love how the 350Z sounds at WOT.

Check out my Vid..its short but i have full 3 inch exhaust from turbo downpipe all the way to the muffler..i have a megan gt turbo muffler..in the vid, i have the silencer in..still pretty loud...

What if the reverse y pipe is only 2 1/2, is the cat back still useless? I called warpspeed a couple of months ago about the exhaust and they said they would call me back with more details. I haven't heard from them again.

I'll find out in a week or so. Just had a full 3" mandrel exhaust custom done today. No cat, no resonator. The downpipe is still 2.5" simply because that's the outlet size on the turbo. I may get one of those custom flanges the Honda guys run that flares from 2.5" to 3" down the line.
Car did 256 whp and 269 torque last week on the dyno. I'm dynoing again next week, so we'll see what the new numbers are. Only change is the exhaust which was 2.5" before.
Butt dyno says it's faster, but I'll wait for the real numbers.

like i said, i'm getting over 300 horsepower to the axles and i'm running 2.5" pipe all the way through.
i'm also Supercharged.
If you're not going to run FI, then a 3" exhaust is wayyy toooo muchhh, it's just overkill.
Going back to my example, i'm running FI with 2.5" with no problem! I'm guessing that until I'm pushing some crazy number, like 450 hp at the axle, i'm not going to NEED to go to 3".
If you have the money to blow, go for it!
If you're looking for performance, 2.5" piping will suit you just fine.
My $0.02 says that you should invest in a good Y-pipe, like Cattman's, and a high flow cat...

Who knows - maybe with a 3" exhaust setup you'd be at 315hp or more? The truth is - noone knows.
I am running just about the same, if not more hp than you. We'll find out when I Dyno, then when I switch to a 3" exhaust setup and Dyno again.
I think it could easily go either way.

Yeah, but remember he is S/C'ed, not T/C'ed...
He could lose low end response do to losing exhaust energy with said 3" system. I'm sure the 3" system will help his peak HP, but hurt his area under the curve.

I think in my case it doesn't pay to go with a 3" exhaust because I'm not willing to run a free-flow muffler. I want the car to be quiet when I'm not pushing it. So I'm thinking a 2.5" catback for everyday driving, and an electric cutout for street warfare. What would be cool is to have the electric cutout operated by an rpm switch, since you don't really benefit from a free exhaust until your at mid-rpm range and higher. It would depend on how fast the cutout opens, though.

At higher gas velocities, it'd be like popping the cork on a champagne bottle, I'm sure. It would literally fly open.

I'd go with the Magnaflow. on_alert had one with his turbo setup, and I really liked it.
I thought about getting a cutout too, but figured that it would just be pointless with a "free-flowing" exhaust. I wouldn't use the cat either (except come inspection time).

Stephen, I notice you said you might use a electronic cutout. Wouldn't that cause some turbulence in the exhaust stream when it's closed? Kinda of a newbie question I know, but I'm interested because I was thinking of doing a cutout for my car possibly.

now i'm really interested in seeing if there's a gain... when you plannin' on doin' it...?
And what do you mean "more hp than you"... you mean i'm not the most powerful max on the org?
Hmmmm..... no2, here i come...
