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.

      @Butters I can't tell you why but the bigger HKS step 2 cams improved low and mid end immensely. Turbos started spooling about 1k RPM less than before and the idle/vacuum was rock solid, it was an absolute thrill to drive, 3rd gear pulls hit 180kmh where previously only managed 160. Conversely, the milder poncoms in there now have a funky idle making it harder to get off the line, drives poorly in lower revs, laggy and makes less power/torque throughout. Feels better after I swapped the EBC but unless I put it on the Dyno again, I can't say how much better.

      Cams are not needed at this power level, they will create lag. The cam gears are a good idea though.

      @Murray_Calavera yeah, I guessed as much, cooler temps, more boost, less knock, more timing, hello power. Unfortunately not quite within reach ATM, could upgrade my whole fuel system to support but still wouldn't have E85 to run it 😂  Anyway, I changed cams again, 260/260 poncam B and everything else the same except an EBC upgrade. Now I must say I was quite disappointed with the result as it was like running stock cams (didn't try to dial them in as they're supposed to be optimum already) but after awhile I suspected my new EBC was underperforming not to mention difficult to use. I recently swapped back my old EBC and it drives much better now, boost comes on sooner, more stable, no spikes etc, feels all quicker and faster than with stock cams. Planning to fiddle with the cam gears and see what happens but maybe skip the Dyno as I intend to revert to the HKS cams cos they really made the car come alive; low and mid end was unbelievable and it just wanted to rev to the moon, finally knew what people were raving about, RB26 really loves revs. Anyway, Dyno 03 is quite disappointing, in Dyno 02 although peak power was less and trailed off at the top, the low and mid end improvement more than made up for it.

      @Darrel It's so tempting to say e85 is borderline magic. It cools the intake charge, so if you're flirting with the edge of the turbos compressor map it helps dramatically cool down the hot air the turbos are pumping. It is very resistant to detonation so you can crank the timing, I don't really want to say you won't be knock limited anymore.... but you probably wont be knock limited anymore lol. I wouldn't be surprised if you made 20% more power swapping to e85 (provided you have the fuel system to support them, bigger injectors maybe bigger pump etc).
