hey all, this may end up being a very un-intelligent question, just so you know, i'm not that mechanical-savvy, but i'm learning! i havn't touched the exhaust since i bought my zed, the loud noise was like a wank to me at first, but now it's just a pain in the ass on my long travels, i'm wondering on how to shut the thing up, i don't mind the growl from the outside, but when all i can hear the whole time my foot's on the accelerator is roaring it just gets annoying, and sometimes it makes a bit of a rattling noise also. so, how do i "shut my exhaust up"? cheers.
to be completely honest i have zero idea of anything to do with exhaust systems. so i'm unsure of anything, any way of explaining what i should be looking for? haha
Get a pair of Lukey straight-through centre mufflers. I got some when I had a loud drone in the cabin and it fixed the drone, dropped volume slighly and didn't drop performance as far as I could tell. I assume you have an aftermarket setup without the centre muffler h-pipe?
I second this. I had a stock system with a pair of canons and it droned like a bitch. Changed to some Magnaflow canons, aftermarket piping with an Xpipe and it sounds like sex. No more drone... Go the mighty Xpipe!
Apexi ECV (Exhaust Control Valve) these are supposed to drop the decible rating down by 10db... alot of people use them on silvia's and skylines, there a tad expensive though so you would prob be better off finding someone local to rig one up using the right sized throttle body and a couple exhaust flanges
U could have got one from Ross (aka Jinxed) But he gave it to ugame! Maybe wait for another group buy... U just missed one. http://www.aus300zx.com/forum/showthread.php?t=288991&highlight=magnaflow Contact rob260 maybe... Otherwise, you can get one made up by a local exhaust shop...
Don't do that Huge back pressure and your EGT's will be stupid. Proper mufflers and a x pipe will fix it. Or get a standard exhaust system and put that on.
if you dont mind the volume from the outside you can sound deaden the inside of your car... put a layer of dynamat in the boot well/walls/floors and it will quiten it down a fair bit..
Hmmm Mine did the same thing, I only replaced my mufflers with Varex Xforce mufflers and the drone went away completely. No X-pipe etc.
2.5 " will be quieter than 3" You can invest in sound deadening material for the cabin. Make sure the car has catalytic converters installed, they remove a few dB. The UAS centre pipe also removes 5dB.
wow there's gonna be alot more work than i thought just to quieten down my exhaust haha, thanks alot for the help all! :zlove:
