hey all,

just wondering if anyone runs a screamer pipe on a road car and if so how much cop trouble do you get with it? my car is only a weekend driver and doesnt get driven hard when there is a chance of being pulled up. thinkin bout custom making a front pipe with screamer and just wanted to see what other peoples opinions are about em on a road car!

cheers cheers!

I run an external gate with screamer pipe. But cause i have the bigger turbo and the external wastegate only opening up when its near full boost its easier to control the noise. From what i have seen on the split dumps with screamers there just a noise bag most of the time esp with a standard or small turbo.

yeah im just runnin standard turbo for the moment and was just gunna make a seperator plate or sumthin. if being driven slow is there any reason a smart cop would be able to pick it? or ya reakon just ditch the idea till i get bigger turbo?

id say ditch it till bigger turbo...

standard turbo comes on boost round 2.5k - 3k so she'll be loud all the time when driving :)

fair call, makes sence! thanks 4 da advice

if they know what there are looking for screemer pipe = $9000+gst. fine. same as no cat converter. cos its a deliberate modification to miss the cat.

most of the time they dont know what it is. they look at it and say "ahhhh blow of valve pipe" lol.

i used to have one. it was cool but got anoying after a while. and i rekon if your car doesnt do tens its not worthy :)

hey this is a good chance to pitch my idea.

not sure if you guys have seen those new mufflers that have a butterfly valve in them so you can control the flow of exhaust and thus the noise level?

well i was thinking why not modify a split dump, so just past the join have either a swing valve, or a butterfly valve that you can control from the car using the same remote that comes with the controllable muffler?

the valve just needs to open and close the screamer or be able to redirect the air flow. that way you have a choice if you want screamer or star fish. i don't know maybe its been done before? The only problem I can think of is a cheap mech to operate the valve that can stand the high temps of that part of the process.

If this doesn't make sense say so and I will draw up a diagram of what I mean, be warned tho I’m no engineering student

Stock turbo = screamer pointless.

It sounds dreadful to begin with, and then you need the dump pipe well made otherwise it leaks trying to vent the internal gate to ATMO which makes it sound even worse.

Your better off with a decent flowing split dump on a stock, or near stock turbo.

That said, I used to run 45mm ext gate/screamer setup on the street back in 2004/05

I wouldnt dream of it in Melb in 2007. Its a massive defect & EPA waiting to happen.

Most people i know have plumbed in ext gates that once were atmo :)

I was defected back in 2005 for the ext gate/screamer, and the law/EPA have only become tougher and tougher since then.

Its really not worth the hassle.

mate has one on his R34 GT-t, i find the sound kinda of appealing and it isnt open that often (if driven right) has been pulled over heaps but never got done for it (combination of luck and stupidity on the cop's part). thing that i dont like about it is the fluttering from the boost controller opening and closing it rapidly. sounds like Hanibal Lectre when hes talkin bout eatin the kidney and fava beans. fs fsfshsfhs fshf shf fhsfs

Just get a straight thru pipe from the cat all the way..

I had it on mine for a day at track day and its freaking loud.. so loud that even with a helmet on and windows up, my ears nearly went deaf!!

heheh

hahahaha yeeah nice example! thinkin its prob not worth it, have heard if you get a cluey cop they will take photos under toys car and hand it onto epa.

as for the open/closable pipe i have heard of it being done using a gate and allen key open close system, buggered if i know how it works tho!

thanks for the info guys, appriciate it

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny
