MSTR32 Posted February 23, 2010 Share Posted February 23, 2010 Hey, my skyline has a cracked exhaust manifold and for ages its just been making weird noises but now it sounds like its a V8. Could it be that the exhaust manifold has cracked right through or is it something else? Bit worried as i only just had the ignition fixed. Cheers.

MSTR32 Posted February 23, 2010 Author Share Posted February 23, 2010 Well it really sounds like a V8 when it revs. And it's running really rich. When it idles its fine but when i rev it, it sounds exactly like a V8 would.

Damo_R34 Posted February 23, 2010 Share Posted February 23, 2010 1. Replace the cracked manifold (its cracked and should be replaced) 2. See if above fixes problem 3. If fixed, eat cake.

CRoNic... Posted February 23, 2010 Share Posted February 23, 2010 Doean't a crack in the manifold make it backfire and sound really tough? Lol. My mate had a Cressida, got a stupid 5" straight pipe through it... the manifold had a crack in it, so it backfired louder than gunshots. He went into the Marion undercover park one time and started revving the shit out of it... flames popping out and it sounded like bombs were exploding... then 2 undercover cops walked out and fined him for excessive noise hahaha. But yeah, his was just a crack in the manifold... letting air in, making it backfire. But it sounded so f**king tough hahah Link to comment https://www.sau.com.au/forums/topic/309357-cracked-exhaust-manifold-makes-car-sound-like-a-v8/#findComment-5101615 Share on other sites More sharing options...

ovrtym33 Posted February 23, 2010 Share Posted February 23, 2010 do u have an aftermarket exaust manifold, if so is it stainless steel???? when i had my old xforce manifold it cracked around the welds (on 2 manifolds) leading up to the flange, could tell it was cracked coz i could hear a tikcing noise it didnt make any difference to performance tho coz we still proceeded to dyno it and still pulled over 300 Link to comment https://www.sau.com.au/forums/topic/309357-cracked-exhaust-manifold-makes-car-sound-like-a-v8/#findComment-5101925 Share on other sites More sharing options...

DIOR 33 Posted February 23, 2010 Share Posted February 23, 2010 i had a cracked manifold when someone went up my bum and it sounds likea v8 but off and you will go through lots and lots and lots of fuel also it back fires both ends and extream loss of power when excelerating also if you havent had damage to crack it then it could be the gasket as that will do the same things as if it was cracked you can pick up a second hand one for not much at all Link to comment https://www.sau.com.au/forums/topic/309357-cracked-exhaust-manifold-makes-car-sound-like-a-v8/#findComment-5102371 Share on other sites More sharing options...
