Anyone have a screamer pipe??

[GTS-t VSPEC]

I'll be belching flames from the wastegate and the exhaust now:D

[EVOIV]

What I would like to do with my next car is have the wastegate pipe exit off to the side of the car, just like Top Secret's Supra. Then you would be able to see flames Most of the wastegate pipes just dump to the ground, and are underneath the car so you can't see the flames, just hear the bark. I guess the wastegate pipe is just like an exhaust without a muffler. The sound probably depends upon the specs of the turbo? I don't think it's affected by the wastegate, because after all it just acts like a valve.

Good choice on the manifold GTS-t VSPEC, hope everything goes well. Should be interesting to see the results. Just a question, when peope custom make manifolds, how do they decide the shape? Do they equal tune/length the pipes of the manifold? Or do they just make it up? I thought equal tuning would be important - to have a constant pressure througout?

[GTS-t VSPEC]

The guy who did mine made it equal length. Once they make one they create a jig, so it's easier to make others:D

[EVOIV]

OK cool, thanks for that. Can I ask how much you paid for it? Is it ceramic coated?

[Steve]

I have a trust type R, which is plumbed back and is reasonably quiet. In fact just about everything is pretty quiet (except the screamer), the exhaust definately is louder with new turbs/manifold but has a really nice note to it, much angrier sounding, but the pod noise is completely gone with the new box.

Evan made my RB25 tuned length ceramic coated mild steel manifold for 1200, ceramic coat of manifold and dump was around $200.

Sounds good Steve. Is the "quiet car" so as not to attract unwanted attention? Eg red and blue lights. That's probably a wise thing. I find it very discouraging if cops are out there and defecting a lot of people. All your hard work has to be ripped off. What a pain! Hope it doesn't happen to anyone, but I'm sure many people here have already had the unpleasant experience.

[GTS-t VSPEC]

Yeah it's being ceramic coated. I'm paying about $1000, cause a mate of mine is making it:D

[Steve]

EVOIV, that's exactly why. I not only want street legal, but I dont want to give them opportunity to have doubts. My car isnt slammed for exactly the same reason - its spot on legal height.

Paul, $1000 for ceramic coating is way too expensive:D

[GTS-t VSPEC]

LOL @ Steve, but not a bad price for a manifold:p

[Jimbo2000]

so are external wastegates illegal?

[GTS-t VSPEC]

Haha, hell yes, it bypasses the exhaust system.

BTW, my screamer sounds wicked, hell loud:D

[Steve]

Jimbo 2000, externa wastegates arent illegal per say, screamer pipes are for the reasons GTS-t VSPEC pointed out.

[GTS-t VSPEC]

True, if you redirect the external wastegate back into the exhaist before the cat then it's legal.

[Jimbo2000]

right, wasnt sure as i'm looking into picking up a turbosmart ultragate or something similar,

heres my problem, not making any difference from 14 psi and over,workshop thinks its cause of the wastegate (T04) it had 2 "bedsprings" hanging off with one attached to the turbo and one not, due to the seller of the car taking it off so i wasnt learning how to drive it with it pushing out close to 1.5bar

thought it was a restrictive cat but later found out that it was gutted anyway, so replaced that with a 3 inch and still the problem remains.

any suggestions?

I just bought a 180 that has an external dump that can be unbolted, so i'll tell you how loud it is in a few days, quite interested to hear how loud it is actually... Good suprise for anyone next to you
