Hi All,

Yes.. I know this topic has been beaten to death, however im in a bit of a predicament (1st world problems) and would like your assistance :)

I just got my car tuned on e85 running 2859-9 turbos, the car made 355rwkw on 20psi  however i was informed that my current exhaust was holding back the turbo (and response). I am currently running a turbo back (3inch?) titanium fujitsubo exhaust which is a twin pipe design and flows out into one larger muffler with an Apexi Cat, it is super quiet which i love, unfortunately max output is 350kw.. I was advised to go for a 3.5 - 4inch exhaust but the problem is i cant find any for a R34 GTR! I can only find ones that fit R33 (i.e. HKS hiper) that are reasonably high flowing. 

Does anyone know any other exhaust manufacturers that will help solve my issue? I cant seem to find resellers either :( 

Or if anyone wants my quiet titanium exhaust for their louder free flowing exhaust, happy to trade with cash adjustments! :D

+1 for the HKS super turbo muffler. It is straight through design with no restrictions or reduced diametetrs inside the mufflers. I just bought one second hand on BidJDM for $500 plus shipping. Quiet too for a straight through design. Have a look on youtube.

Check out AM Performance - they did my Titanium 3.5".  They're Adelaide based but Andrew can make one regardless - just make sure you're running an R34 sized cat, not an R33 one (shorter).

Will suss them out too! Another titanium would be nice

Get the entire exhaust. Remove it from your car and flog it on ebay. You can build a very very good 4" system that is very free flowing with a nice quiet note and no drone. Honestly, the off the shelf stuff is literally shart.

I have almost the exact same combo, but I have cams.

I had my fabricator make me a custom setup so my exhaust is as follows.

  • HPI 3" Dumps.
  • HPI 3.5" front pipe. 
  • Full 3.5" Vband exhaust, "special high flow cat".
  • Magna flow mid muffler. 
  • Apexi Evolution Rear muffler. 

Car is quite and makes good power. 

I will say you wont make much more power by changing exhaust until you put cams in it.

Ill have a look into it. It seems custom is the way to go. Will speak to an exhaust shop, i wouldnt mind modifying the HKS exhaust, however if i can get the same quality if not better for cheaper then will take a different route.

      Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

      Leak from Tokico BM50 Brake Master Cylinder

      The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/
