you'd be better off just putting a silencer in the rear, like what most systems come with. no cutting, and much cheaper.

thats what i was thinking but for some reason the blitz nur spec dosnt come with one...at least the one im buying....

I had the same exhuast, it still failed EPA with the silencer in by 2db... i had to install another resinator into the system either that or install a mid muffler.

By installing the silencer your car will aslo stop making power at a certain rwkw like mine did..

noise and restriction are proportionate. I don't care what anyone says about their quiet system that doesn't cause a restriction.

Basically, it will be more restrictive if you make it quieter. The question is HOW MUCH that restriction affects your GIVEN POWER OUTPUT.

Personally, I run a straight 3" pipe. Most possible power, minimum possible restriction.

BTW, I have an ecv in my car. It's very restrictive. The car feels like it accelerates about half as fast. you can watch the revs climb if you stamp it, and it is really choking. Whereas, in first, if I normally floor it, the rev needle just smacks straight up to the red.

Regarding the rear plug in silencer (buttplug), i find mine to be quite restrictive like the ecv.

Regarding the centre muffler - refer to my first point regarding noise and restriction.

btw, ecv is not 200

firstly, it's 300$. you need the 81mm version if you have a 3" exhaust.

Then you need an exhaust shop to cut off one of your flanges, then weld in the ecv.

It's u to you whether you want to quieten it down. personally, i want it as loud as possible.

Why do you want the Blitz?

The Trust Power Extreme II is very quiet but still gives off an awesome growl when you give it to it. I believe it is also 88dB alone (stock dump + front pipe) as well, so all legal. (Info from Trust site)

Dont waste your time with the apexi evc i hav it and had nothing but problems with it so its now wired fully open.. spend the extra cash and get yourself a legal exhaust system.. best iv seen are CES exhaust systems in brisbane.. they will hav a system in stock to suit your car and guarentee legal db's and 20+kw gain...

      After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive

      Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.

      I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
