Xforce Varex exhaust systems road worthy? Seem to recall close able valve exhausts not being road worthy for some reason, but double checking given its a standard feature on plenty of cars including mine... Brother is thinking about getting one for his mustang but personally I think it's a waste of money paying for something I'd never use, and more so if it's illegal in itself anyway...

So apart from the possibility of closing it around a cop car in an attempt to avoid being sent to the epa, it has no actual upside if you are sent to the epa... Unless it's under when fully open, in which case it's pretty pointless.

Given my brother is 35 and doesn't hang around the local maccas car park, he'd be better off getting a normal exhaust which is probably cheaper

Factory exhaust technology = road legal cause engineered blah blah and exceptions just like HID in factory cars and Harley Davidsons being ridiculously loud from the dealership.

Aftermarket / varex = technically not legal, even if it's under the limit when open...as far as I know...many cops will treat it as a defectable item.

Workshops...who knows...when I got an EPA done the guy said he had to test it with it open. 107db. So had to remove and put stock exhaust on to clear.

A friend of mine finds their varex useful and uses it all the time, not just around police but for not bothering neighbours late at night or eliminate drone on freeway driving etc. Some people just leave them open full time though. Varex + hotdog mid muffler is a good combo.

You broke the speed limit, why do you think you should get off

Because I'm a law abiding citizen who has drastically improved my driving record in the last 5 years. Rather than get cheaper rego (the logical reward), I get off one minor offence every 2 years

I've been thinking of varex-style solutions because straight pipe SC430 sounds like fun, but obviously only at the right time/place (3UZs are notoriously quiet even with straight pipe, compared to other V8s).

Driving behind one of those Porsche mini SUVs and I noticed the outer exhaust tips have motorised valves in them, if fitted to a cheaper car might be a worthwhile wreckers find.

Write a letter - admit guilt and misunderstanding. Will get official warning if clean record.

 

They won't let off anyone who runs a red though

Only if less than 10kph over

 

Also there is a specific template letter you have to use for some reason

The manual apexi valves are way better, but discontinued now.

uwotm8?

That's like saying those remote control cars that - didn't come with remote controls - the electric ones you just turned on and they just spun the wheels until they crashed - are better than actual remote control cars. f**k you very much.

Seems odd to do something so simple with an electric motor and crappy Chinese products charged at a premium. I was thinking of having it early in the system and be more of a bypass valve, not like a muffler that blocks flow when closed

    • Ahh got it. Well maybe install a drain for the catch can somewhere down low and accessible like a wheel well too....
    • Before you blow your car up, have you checked you've made all the correct modifications to the wiring if you're still using the RB20DE loom?   Some things to look at: The pin used for the map sensor on the RB25DET, is the same pin used on the RB20DE for the Ring Gear Crankshaft Position Sensor, no idea what you've got it plugged into now. The turbo pressure control valve solenoid you're talking about on the RB25DET, the same pin is used for the Variable Air Intake Control Valve on the RB20DE.   The factory manual has the wiring pinouts in it for you to check everything. It also has the diagnostics process to read codes out. In addition, there's a great table that shows what sensors and what actuators not functioning will relate to which signals. And Nissan confirm the as everyone else has from experience, the Solenoid being disconnected won't cause a fuel cut. However, the turbo pressure sensor being missing / wrong, WILL cause a fuel cut. https://www.nicoclub.com/service-manual?fsm=Skyline%2FR34-Workshop-Manual-English.pdf
    • I've been hunting info on the G Series II - this is best I have found so far(Link below). Still waiting on the G35-1150 comp map, kind of very keen   So how do we go about getting precision on that little table of yours ?   https://turbosbytm.com/sites/default/files/product/technical-info/Garrett-G-Series-II-Product_Flyer 25 30 35_1.pdf  
    • yeah I get ~0.6L per session into the catch can. very ethanoly. It ends up overflowing out the breather of the catch can on circuit days too even with a 2.3L capacity catch can and I only drain out ~0.6L max. So every session I have to come in and drain the catch can, which is a hassle. So this is me cracking the shits and doing everything I can without removing the motor (back of head sump drain/breather and oil restrictors off the table). plans short term are: full length splash plates remove oem cam cover baffle add foam and reinstall at -10 or -12 AN fittings to the side of the cam covers down to the sump (luckily I already have fittings in the sump) Yes the ~340,000km unopened motor is probably not helping things
    • I'd use any fuel safe foam....mine went in 15 years and 15 rebuilds ago, still getting reused I'd have to say I don't understand swapping to studs to fit a particular baffle unless you are having a massive blowby issue, and even if you are addressing crankcase not head breathing is probably the next step.
