Hi peeps,

Need some info on this before I head off to a muffler store. I have a 3inch (i think its cat back) exhaust with a cannon tip muffler which all came with the car direct from japan. Trouble is that under some heavy foot acceleration, the exhaust gives out this loud nasty pop when the gears change. I dont want to loose the 3 inch pipe work but the sound has really got to me. Anyone else with this problem? what exhaust do you guys have on your cars?

My wifes RS4 does the same thing. I think they over fuel a bit on lift off and hence the pop. My 260RS does the same thing with the standard exhaust (she does flames though, which is cool). That is being changed soon. I wouldnt worry too much about it,

Cheers,

Ken

Sounds like the wastegate, but mine is more of a brrrt sound than a pop, mine is 3" turbo back.

Mine pops on overrun, and quite regularly too. Mine has the standard ECU, but it's been converted to manual, so I can kinda induce the popping at will with some heel-and-toe or throttle stabs on downshifts.

Dunno if it shoots flames, but I'd like to find out. Might either get someone trusted to drive it one day as I follow, or get someone to follow me...

Nope, ONLY myself and the wife drive it.

The only other time I have let someone else drive it was one of my best freinds when I was married, and even then I wasnt happy abou tit, but the wife insisted that we rode in the back, <sighs> so yeah.

No I do not like the idea of someone else driving my car, it is hard enough letting the wife bloody drive it.......... :D

Hei SKA so what you are saying id you value the car more than your wife?

:( AHAHAHH!!!!

Well to tell you the truth though i dont like people driving my car as well.

i LOVE getting driven by in my car

nothing like hearing YOUR car SUCK, FLUTTER and ROAR past :(

Then you think....so thats what it sounds like when i boost off in front of someone in a "fast" car, muahhaah

I got told my car sounds like "someone roaring and ripping their throat open at the same time". I was like, oooooo, then yeh, it does :D

Well i run the bog standard factory ECU so can't really say if im running lean or rich....good enuff cause to get a stoich meter installed. anywayz if the car runs rich on the standard ecu ...does that mean we can get away with using 91 ron pulp?

and just side tracking on the issue, how much boost can I run on the factory ecu before the injectors max out, the fuel pump suffers a heart attack or the MAF goes crazy <<whichever comes first

Mine is a stocker with 3" cat back. It always has a nice burble on back off with the odd snap crackle and pop up the top, after hard acceleration.

Exit is very sooty, dont know if it flames. Got to get the DFA finished and fitted.

hey fcruz3r, check your plugs and buy new ones and gap them at 0.8 this shoulf fix your problem reset the computer and put BP ultimate ot shell optimax in and it should be as good as new and wit the pop in between gear changes this is normal as long as its only one missfire

dont you guys let other people drive your cars?

not a chance in hell, ive already had one of my cars written off by a mate and i'll be damned if im gonna let anyone drive my car again. not even my girlfriend.

the other day my dad moved my car from out of his workshop to the parking bay (about 10 metres) and put the front bar into the gutter.....NOT HAPPY JAN!

The Autech front bars are a bitch, they sit very low (aftermarket sus doesnt help) and stick out a mile. Mines been off once for painting and is just about due again!

Thanks for the tip QIKEXT. Yea currently its just a single loud pop between gear shifts...must be just an RB thing. I'll get the new plugs anyway ...do you know the exact code number/make for the oem plugs? what about resetting the ecu..how is that done...is that like disconnecting the battery terminals for a couple of minutes before putting them back on?

I thought to reset the stock ecu, dissconnect battery, pump the brakes to discharge any capacitors still holding charge through the brake lights, reconnect battery.

But I still fail to see what that actually accomplishes, I mean it doesnt store any data, does it?

    • I've looked up the parts number (41011AL501). It's around $700 OEM. Usually our Infiniti G35 here in Canada have interchangeable parts with my Stagea but the parts number are not the same. I have looked around and it seems the JDM 2005 V35 Skyline (which is the same as our G35) has the same caliper but I cannot confirm. And I can't find a repair kit. The inner brake pads drags on the rotor, seems to be rusty piston. Thanks for the info by the way
    • This coupled with 6-9 speed autos with ridiculously short gearing is why these modern shitbox cars always seem so fast off the line. If it wasn't for those things, Raptors would not seem fast. The problem we have is there is a driveability gap between a more gentle take off and a wheelspinning sideways launch. The difference between ankle flex required to achieve one and ankle flex required to achieve the other is about 0.5°.
    • Yeah I think I'm also with the opposite here. It's 'hard to keep up with traffic' because in the real world I'm accelerating with 15% throttle and they are pinning it. It feels like I'm being an overt dickhead at anything above 15% throttle, so the car sounds like I'm being an overt dickhead to keep up with/get ahead of traffic when I'm really just trying to drive with traffic. There would be no issue 'keeping up with traffic' if we used the same level of throttle input/aggression to drive around. People really do just drive around with their foot nearly pinned in econoboxes.
    • To be fair it's the other way around. 300kw is boring in a modern Golf or BMW. They are so competent / well-engineered / devoid of emotion that you have to go stupid fast to feel anything. Whereas the <300kw RB still makes all the right noises and it feels good to drive. Can pull off at the lights with the turbo whooshing and the blow-off pssshing and feel like the coolest kid on the block. Just don't look to the side where you'll see the bored housewifes in their shitbox Yaris/Corolla/Camry that kept up because you didn't go fast at all
    • 300kW is so boring in a Skyline, you'll get spanked by someone's mum's Golf with Alibaba pipes, and an email tune.
