i think whoever told u HKS zorsts where loud has a few things to learn, i have a HKS System and it is not very loud at all, it basically just gives the car a really nice deep note, doesnt drone, and still has all the performance benefits.

i have a 5zigen cat back, 2 3/4 inch, it could be a turbo exhaust im not sure, but its drony and loud only between 1500-2000rpm

Rest of the time its more then fine.

My car has this very distinctive exhaust note and this nice throbbing, any one else have this. Im sure its from the RB25 engine :D

hey nismodified - the throbbing ur talkin about - ive got it too! sounds pretty good eh?

do you get a different, louder sound generally when cold and in lower revs? kindof a slapping, throbbing through the zorst - cause i get that for bout 5 mins every morning - neone know what that is?

i dont get that sort of noise, but i know of another Rb25DE that does have a similar noise u described

mine has a very deep note, but its hard to describe since im always inside the car when it revs thru the rev range :(

ive been thinking about making myself a straight thru pipe for sometime now..

within the next few weeks i have access to this computerised oxy cutters and welding gear, i should be able to cut some flanges out of 5-10mm metal plate....2.5" piping wont be hard to get,...weld me up a straight through pipe....for off road private use of course

I got a simple muffler fitted to my car for pure fx, coz i have no money, the muffler is 2.5inlet and 5" outlet, it makes a hell load of noise but in certain parts of the revs, ie: 2000-3000 main offender, it makes a shit crackling/snapping noise, i have NFI what it is but it ruins what is otherwise a really sweet sound.

i like the crackleling popping noises ;) but thats me

it happens to me usually when i back off the throttle on decent revs.

It should be cause by unburnt fuel passing into the exhaust system.

A simply solution to get rid of the popping, if your not using 98octane fuel, then a switch to optimax, synergy or ultimate may clear up or at least reduce the noises.

    • 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?

    • 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/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
