hey all, ive been doing a bit of research on here via the search function and talking to exhaust places about upping the db on my system, i have a 3" bell, hiflow cat, 3.5 inch catback with hotdog and fujitsubu jasma cannon, the exhaust sounds nice, but, is very quiet due to the jasma cannon, one of the exhaust places recommended xforce for a cannon because they have a 3.5" inlet version (which is what i need) and they are aparently head and shoulders above "Genie" which is what i asked them about to begin with. what do people think about the xforce cannons? who has one? what sort of note dose it give? how loud is it?

im a bit unsure about xforce, but a few people on sau have them and havnt had any issues, but yea, id like a jap brand one, but obviously theyre a lot harder to track down, id settle for an xforce one if they sound the part and are a bit louder than what i have now.

what you guys think?

edit, forgot to mention it was a stock turbo setup

i was under the impression the hotdog only takes away drone?

Nope, I had 2 hotdogs and they only took away the noise from the upper ranges. Idle and drone didn't change much, perhaps just got deeper.

Mate I've got a full 3" X-Force cannon system and apart from some fitment issues with the entire system (i.e. it didn't fit and has been back twice to get re-fitted properly!) it is still pretty good bang-for-buck.

The cannon muffler is a nice piece of stainless steel that looks and sounds the biz. I think they are about 93db when new which is loud enough to keep me happy but not so loud as to attract the wrong type of attention :rolleyes:

Their hi-flow cats are good value for low-mid range horse power applications too.

Bascially you can't go wrong for the money and it sounds way better than the jasma crap that was on there previously.

cool mate

im not looking at changing the whole system though, just the end cannon.

yes the jasma thingo inside the cannon isnt the greatest, not sure if it reduces flow but its smaller than the rest of my zorst

Not sure whether you knew but jasma is not a brand, it is a japanese standard for exhausts and a big part of that standard is the noise level so basically they are all pretty quiet and restrictive.

yep i know this, ive heard that the way they design the jasma zorsts dosent restrict flow? is this correct?

yeah i don't think there is too much of a performance hindrance, considering how many people have JASMA-rated systems.

RUFFLS had a back-to-back dyno run done recently with and without his catback exhaust (3.5" fujitsubo, JASMA stamped) and the difference was negligible, 2-3rwkw or so.

yea as i thought

but this isnt for the performance boost, just after some more loudness in the system thats all

Just remove the middle muffler/resonator, it'll be cheaper and you'll retain the decent muffler at the rear.

cannons look crap don't get one. You have a turbo car so most the drone and rasp will be muffled by the turbo anyway.

My HKS Hi Power Silent is JASMA stamped, and i dare say its not quiet, and its def not restrictive haha.

what do you guys think about just getting rid of the middle hotdog? because thats all thats there after the cat, just the hotdog then the cannon. what will that do for sound?

Yeah, it's probably worth giving it a go, rather than spending up on a complete system first. It won't cost much to get an exhaust shop to do it, so not really a big deal if it doesn't deliver the result you want.

My car is running 3" catback, with a single cannon at the end, and it's pretty loud.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.

      The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.

      Just like in being 14mm too small (296mm) makes it not fit, being 14mm too big (324mm) it also won't fit. You want to find the correct rotor.

      @GTSBoy Ok so that was the shops problem...they showed R33 rotors on R34 page and i did not know 296 do not fit(and are for R33) Yes i bought "kit" with rotors and pads. Pads are ok(i have GTT calipers front and rear). They have some 324mm but no 310mm. So i dont know if they would fit. I have 17inch LMGT4s So another question. Can i fit those in the rear or they are just "too" big for that?
