R34 Exhaust Please Help

Recommended Posts


Ive got a cat back exhaust only with cannon on my r34 Auto. IM considering upgrading the whole system to a turbo back, but im worried on doing this.

The reason why, is with this current exhasut the car sounds great, but while cruising at liek 80 plus and highway speeds etc, the car has a really loud droneing exhaust tone..

im not sure if this is because the autos are only 4 speeds, making the car rev higher causing the drone, or its the exhaust..

Basically, any guys with r34 autos or just mechanical minded people who know anything abot this, please offer their experiences or how to fix it?

any help would be fantastic

thanks in advance

easy fix, do the whole exhaust as per normal, 3" dump pipe and front pipe, 3" hi flow cat, and just replace the canon muffler with an oval 3" muffler. this is the only way to get rid of the droning noise. its just a inherant quality of the canon. and oval muffler will be quieter but still perform just as good.

you are correct in what you show me. thats exactly what you will need. it removes the drone noise to a point where you can barely here it cruising, but give it a kick in the pants and you can here it a little.

y does it happen? coz there is more room in an oval muffler, so quitens down a bit, with a cannon you might as well just have a straight pipe, thus the drone.

    • Here is my 2013 Nissan Skyline 370GT Type-S has a factory Nismo exhaust and Enkei rims. Shes completely unmodified. Brought her from Cult & Classic and drove down from NSW to Tassie November last year. 
    • Yet another thread bump because I want to talk about this: The general gist that this guy found for a MK7 Golf GTI is that by adding a venturi from a 2022 Tiguan he managed to pull crankcase vacuum far more reliably under boost which effectively stopped oil consumption on his engine in track conditions. An earlier video details how that venturi works: Basically one port is atmospheric vent, one port goes to a boost source, and the last port goes to the crankcase vent. There's a lot of discussion on here about scavenge pumps and all that fun stuff, why not try to replicate that by pulling some energy off the compressor? There is one catch though and that is that the PCV diaphragm on these cars appears to completely block off airflow from the intake when there is enough crankcase vacuum. This contrasts with the RBs where there is basically nothing stopping vacuum from the intake from sucking a big gulp of oil if it gets into the crankcase vent.
    • Hi All, Brought a 4 Door 2013 Skyline 370GT Type-S in November last year. Absolutely loving the car, noticed a few audio issues speakers cutting in and out and the 12V circuit seems to be completely dead (after checking and swapping the fuses) but just wanted to say Hi     
    • Could you please express this thought again with some clarity added?
    • So, whilst the Bogan Cruise Ship is GTG, and I had organised some time today to go on the SAU NSW cruise, my best laid plans where kicked in the balls, well, kicked in my right knee to be exact Now, after a bit of arthroscopic "honing" and tibial band lengthening "modifications" , I'm sitting on a couch in a prescription induced drug haze, watching 5hit on the Youtubes and falling in and out of consciousness......good times
