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...

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
