Hey all,

I just had my new exhaust fitted to my R34 GTT today!

It consists of:

3" Split Dump/Front pipe supplied by BOS Importing (BATMBL)

3" > 5" > 3" high flow Catco CAT (200csi cell - 706.2 CFM) supplied by BOS Importing (BATMBL)

3.5" X-Force Cat back section with oval resinator

3.5" Inlet > 7" Cannon > 4.5" Outlet X-Force Muffler

All stainless steel mandrel bent... very shiney! lol

Total Cost was $1634 for supply, freight and fitting all up.

Noticable differences:

- Turbo Spools much louder

- Boost comes on quicker

- Car is quicker through 1st - 4th

- Cannon looks much better out the back... big and shiney lol

- BOV seems a bit louder

- Exhaust is louder, but not overdone because of oval resinator rather than hotdog

- Exhaust sounds very nice when cruising or with no throttle (drone)

- Exhaust is definately not illegally loud, and comes with silencer also

Recommendations:

- Get the hotdog resinator if you want it really LOUD

- Probably not worth the extra $100+ for the highest flowing CAT (Not much noticable difference)

Hope this helps anyone looking at getting an exhaust!

Thanks.

Hey man,

I got the whole system fitted locally on the sunshine coast for $185.

The X-FORCE cat back section was $699 + $40 freight.

Hope this helps!

Thanks.

  • 1 month later...

maybe the higher flowing cat would only come into play with other mods that up the kws? any other thoughts?

or maybe i'm just trying to justify my iminent purchase of the same 3-5-3 catco you got. i figure it's a bit of future security.

    • HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.
    • The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.
    • Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?
    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
