Hey guys,

Looking at upgrading the exhaust on my R34 GTT over the next few months. I was just wondering what my best options are for with:

- Quiet on idle

- Loud on high RPM

- Offers the highest performance

- Budget of $1,000

Anyone have recommendations and stores to buy from?

Thanks

For highest performance you'll want a full turbo back including dump, front pipe and a high flow cat.

I'd offer a couple of other requirements to add to the list if I may:

  • Properly fitted and tucked in for maximum ground clearance, there's nothing worse than scraping your car or mid muffler on speed humps all the time
  • Not droney at standard road speeds 60, 80, 100, 110

The cheapest may not be the best. I have a full frankenexhaust mixed from random parts, it fits well and performs great but is droney and probably ended up being more costly this way too...

This doesn't really exist with the budget you have.

Unless you want to buy like, someone's second hand exhaust and then do a little modding/fabbing to make it fit and work with your setup as every setup is a bit different.

In other words, buy my old exhausts, thanks - Nothing off a shelf is going to satisfy the criteria you've listed

$1000 will only get you something second hand if you require turbo back and it will either be loud or restrictive.

I'd probably try to find something second hand that flows really well and stick a decent muffler in it.

I can probably compromise on a few areas for now. With just a basic exhaust surely $1,000 is sufficient? (Excluding installation)

It can be done, try Jesse Streeter or Import Monster and see if they can supply a Fujitsubo Legalis or similar. Understand these will have a restrictor inbuilt and will struggle to make top end power, but will sound great and be legal or close to legal dB.

Otherwise there are quite a few places that could do a custom stainless system for that coin.

Buy a cheap mig, a hooker aeroflow, a Berkelee straight through.. Some pipe and bends.

Make. It.

Then you also own a shit mig welder. But it's an exhaust. So shit welds are ok.

That's what you get when you pay an "expert " to make one.

You will either crash car or sell it before exhaust wears out......or falls off, depending how shit you weld.

Google. How to weld.

If you want to get some ideas for a modded setup here's what I have:

  • JJR 3" bellmouth dump/front – customised (to ensure good fit with my Hypergear IWG, and for ground clearance)
  • Venom 3" high flow metal cat – flows much more than the XForce I had first
  • Custom 3" piping between cat and mid muffler
  • Small mid muffler – for good ground clearance
  • HKS Super Drager 3.5" to 5" rear section and muffler

It would have been cheaper to build a full custom system rather than mixing and matching parts over time but oh well. Also full second hand systems for the sedan are like hen's teeth.

And get raped hard. What a bloody stupid idea to promote...

A decent exhaust doesn't improve in power when you drop it.

LoL one out of a million effective methods.

My R34's pumping 380rwkws internally gated with exhaust dropped, make no where where near it with 3 inches exhaust back on. I'm sure you will come up with a quite alternative.

I have a full turbo back system to suit an R34 sedan that I may be willing to part with if anyone ever requires one.

Psssh, I have two of them! :P

How does that system actually work? Because looking at it, I actually thought it was a better (i.e, far easier to hide) system than Scotty's "external gate on housing" setup.

Then again, why not just simply make the dump diameter that size?

Car is currently running a full 3 inches SS Havoc fabrications turbo back exhaust with two megnaflow mufflers keeping it quite.

The idea is getting back pressure out of the exhaust system. Valve is spring pensioned that is forced open by exhaust gas pressure when > 3psi. It is currently opening at WOT in 3rd and 4th.

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)
