Cracked Exhaust Manifold Makes Car Sound Like A V8?


Recommended Posts

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.

need more info...

sounds like a v8 as in running lumpy??

sounds like a V8 as in it goes ''omgggg thatz siiik''??

upload a youtube vid. or add a better description.

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

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

Damn that would of been fun in the carpark making banging noise lol

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

    • Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes 
    • I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.  
    • Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days
    • It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
