Except I had an 80mm Fujitsubo Legalis R pass noise emissions while flowing 300+kw. There are good exhausts and there are cannons. :P

Yep; they are a great thing; I'd much rather have it on, and never get hassled.

Using a sound meter app, and in the garage, with a bit of reflected noise; mine runs 80db at idle, and 90 at 3000rpm.

When I built the split system for my C34 I was looking at using 2 Varex mufflers side by side, but the cost was going to be too much. So I was looking at what else is available and found Dynamax VT mufflers which for 2 was less than the price of 1 Varex.

These use the same sort of thing, a butterfly valve but they are spring loaded. At light loads they remain close and under full noise they become near enough to straight through. They are nice and short in height and don't look any different from a standard muffler from the outside, which for me is plus. Once the car is warm, it's quieter than factory, but with a slight rumble to it. Full noise and it just screams.

Here's the only pic I have that you can see the valve in mine.

Lots of clearance when tucked up high.

Thats cool was it easy to order, so the site

Slightly off topic here; do you guys get randomly pulled over in your M35 Stageas? Spoke to a friend who drives an import and he said two things which may have explained why I spefically got pulled over:

- driving along Princes Highway at night where it is very common for street racing/traffic light drags to occur

- though the M35 Stageas look understated, they are starting to build a bad reputation by cops who specifically target imports

Nope, the only time I have been singled out and pulled over I deserved it.

Distant police car in the opposite lane caught me on a near-deserted road... momentarily airborn off the down side of a bridge... doing near 150kph in a 100 zone... D'oh (yes we had to be somewhere urgently, but still...)

All the coppers think it is a volvo anyway, especially the AR-X from a distance...

    • OK, so all I can suggest is that - if you have all the parts, and you have all the wiring looms, and you have all the electronic modules, then....it really is just a wiring problem. You likely have a damaged wire, pin, etc, somewhere.
    • Yup, bought this bad boy and hopefully it will be ready to pickup today. Had $5 credit on top of it so it worked out really well!
    • Yeah it is really until until you get a feel for it....then it is easy. Which is no use to you really. I'd buy that torque wrench. One thing from sure, many (most?) tyre shots overtighten the f**k out of wheel nuts, so don't worry if they were tighter when you tried to take them off compared to when you do them up. I've had some crazy tight ones come back from shops, quite apart from the potential damage to the thread, I can't see a smaller person taking the wheel off on the side of the road
    • Hey mate, thread dredging hahah To answer you directly, yes I had my itbs oversized and custom butterflies etc made by EFI Hardware in Sydney back around 2017-2018 if memory serves. My setup had a vast amount of other changes too though, so no direct comparisons unfortunately. i went from oem itbs, HPI manifold and internal gate hks 2835 pro S; to 49mm itbs, cnc port matched Nismo plenum, RB25 Neo lower runner adapter hand port matched, r31house v2 Takoashi MAX equal length twin scroll manifold with twin 38mm tial gates and a FP HTA3076 with 1.01ar twin scroll real hosing. feom power Fc to a link fury wired by 12volt, r32 gtr fuel tank conversion with frenchys twin 460 / surge tabk fuel hanger combo kit, 1659cc injectors, full 4 inch turbo back stainless exhaust, Z34 6 speed, Tomei 2way with 4.3 final drive and a ton of other shit. ive posted elsewhere here with complete run down, but here's a graph from its initial tune with no boost control on, 20psi gate springs only and e85.   7542AE72-DA92-4E0B-8660-B0940FEA7F24.mov
