Nismo Exhaust Q

[illusiVe]

well i have a R34 with factory Nismo crap exhaust.. atm the sport function is closed.

i flick the switch and u can hear it attempting to move, but it dont move at all.. ive even taken the spring off both the exhaust + actuator and cant even pull it with plyers to open/close..

i've WD40'd it.. no change.. ideas until i can afford a full exhaust /tip

Yeah apparently they pretty much all do this after a bit. I've got a cat back exhaust going pretty cheap if you want. Send me a pm.

[illusiVe]

thanks for offer dude

im just broke atm.. just bought the car and got my cf bonnet on it.. got coils on the way 1st since the car drives like a boat atm.. can barely feel the road.. i hate it.. i want my no-suspension feel back

once i get to that point.. ill see if i go FMIC or exhaust 1st

found solution:

step 1) take off the rear muffler

step 2)proceed to bash with hammer until it moves, if it doesnt move, break the muffler so have the exhaust pointing out the back of the car, not at the rubber on ur wheel...

step 3) admire your hard work

god i love being dodgy

Keep Spraying it with WD-40 until it comes loose

Then make sure it's clean and freely moving

then get High Temp grease like the stuff you use on Brake Pads.

Lubricate mechanism.

Job Done.

hey illusive...sold your 25gt?...or you turbo it?

[illusiVe]

yup sold my 25GT bought R34 GTT

its red

[Beer Baron]

well if the little motor is still working (sounds like it is) i wouldnt bin it yet. just keep using a penetrating spray like bass junky suggested. it should come good.

[Howie]

Mine's sealed shut since i've got it, but i'm wondering does the sport (open) mode make a noticable difference at all?

I'm going to try to lube it up and get it working again

[nuffsaid]

I had that exhaust, without the motor or controller though.

To open it up, I just got underneath the car and turned the adjuster manually.

So remove the wire off it, spray a crap load of WD, and try to move it by hand at the back of the exhaust.

[Howie]

Thanks for the tip mate. I've let it soak up in wd40 and i'll give it a shot tomorrow morning.

Say guys, how's the nismo exhaust in terms of restriction? I'm just trying to sort out priorities for modifications right now and wondering if i'm being bottlenecked substantially by the exhaust and if it's worth me spending another 1k on a turbo back system (or another cat back for that matter).

[GtstCoupe]

For memorie it is only 2.5 inch so a 3inch will still be a gain and the

rear muffler is still a bit of a restriction so yeah a , highter flowing cat back

will make a differance and frontand dump in one plus a 3inc cat

will make quite a substancial difference.

and will be stainless if you choose as opposed to mild steel

so it will have better heat dispersion properties.

hope this helps

[Howie]

Sweet that's very helpful.

Say does anyone know the diameter of the stock (non-nismo) r34 exhaust? and does anyone know if the exhaust control valve can be used on any aftermarket exhaust systems? Reason I ask is, i unfortunately live across the road from the road transport authority where they often set up defect stations ... they've been wanting me badly for a long time now

[T04GTR]

i thought only the n/a r34s have the duel stage mufler

[GtstCoupe]

it is still2.5 inch for stockbut you have ecv and also higher flowing muffler on the nismo exhaust, and you carnt really adapt it to any other

exhaust ,apexi to make a ecv but is not cheap and does not drop by many db,s and i think the epa would test with it wide open anyway so not really any point with having it, just make sure if you get an aftermarket system that you get one with a middle muffler as opposed to say a blitz that is just a hot dog, and you shouldbe safe with that.

[illusiVe]

best thing to do is get a cheap old throttle body (as thats practically what it is.. drill some holes thru it so air can ALWAYS get thru, then hook the spring up, press the valve button to make sure it can open/close. with the strength of the spring.. and ya done

very stealthy too... plus its factory so they cant fk u for it.. although u may want a TIP which helps the stock look

total cost $50 for 3" throttle body $20 for the weld in of it.. 2 hours of work.. $50 of beer while working on it

What? How does the heat dispersion properties of a metal improve it's function as an exhaust? If I remember right you want the heat to stay inside the exhaust to improve the gas flow hence why you coat exhaust manifolds with ceramic.

[GtstCoupe]

Yeah you are correct ,i ment in regards to cool down and heat up.

of couse you need a steady temp to have good exhaust flow and to

scavange as well,i was up to late last night lol
