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...

    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
    • ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
