Well its not really just GTR tax, Akrapovic charges high for all their exhausts. Its about establishing a premium brand, and just like all premium brands are they overpriced? Yes. However you get the best quality, the exclusivity and IMO best sound too.

Worth the extra outlay? Well if the GTR is your dream car and you want the very best parts for it, yeah for me it is. In the process of sourcing one now.

90% of the extra sound in a catback system comes from going catless in the midpipe - thus best bang for buck exhaust mod is midpipe only

the best sound (and power) comes when you go catless on the downpipes, and you won't really understand how much better it sounds until you do it

muffler only is really just increasing the volume of a bottle knecked system. I know because i did my exhaust in 3 stages - catless midpipe (great sound), muffler (slight increase volume only) and lastly catless dp's (complete change in tone, more raspy, more burble crackle/pop on overun, significantly improved turbo spool)

i was initially looking at spending 7k on the amuse system but what stopped me is the GTR tax - Amuse charge half that for the 370Z system which includes more ti and more mufflers, and that's just taking the piss

someone only recently pointed out my 997 gt2 has an akro exhaust from oem, so i guess that's given them the excuse to jump on the GTR tax bandwagon

i spent just over 2k for my cat back, looks fantastic and works even better. Been running it for almost a year now with no discoloration of the ti. One of the best buys i've ever made mod'ing cars.

each to their own, this is just one person's feedback

I ended up with the Willall, doing a two-step thing like Domino and agree that the rear section added more noise but the mid pipe makes the bigger change in sound from stock.

Keeping my warranty precludes me from doing downpipes.

Let's all remember we are driving a TT V6, no exhaust will make this car sound like a GT3 or Scuderia.

Considering the cost, weight, material and backup with the Willall product, it's hard to go past them in my opinion, unless you can get lucky on Alibaba like Domino did.

^^^ Steven, nice of you to join up on SAU to advertise your business - NOT. As you would realise, if you want to advertise on SAU, you need to become a sponsor. Consider this your first and last warning.

When installing ECU flash and or Exhaust, the car needs to be tuned on a dyno, is hub dyno or wheel dyno better than one another? Personally I prefer the wheels to stay on in case they damage the rims or brakes, what's everyone's opinion?

Cheers

i bought my exhaust direct off alibaba from one of the ti exhaust manufacturers in china

it's 90mm, sounds great with de-catted downpipes and catted midpipe (didnt gain much sound when i added this to my midpipe only though - it's same layout/design as oem afterall), smooth quality welds inside and out, and looks even better

Following this trend, I thought I'd try a china stainless exhaust off E-bay.

Picked up a catback for about $700, and a midpipe for $260 (after a couple of bids) plus about $100 delivery all up. Honestly, at that price I really couldn't refuse.

Seems good so far!

I had the Willal mid-pipe installed on Friday. The car sounds a lot better now though still pretty quiet and tame. I did a drive up to Harvey Bay and back overnight on Friday and very happy with how it cruises at highway speeds - no droning etc. They are a pretty noisy car imo with heaps of road noise etc so I'd much rather it be noisy with the exhaust. I might consider doing the dump pipes now but then have the considerations for cats - catless or high-flow in the dump pipes or the mid-pipe???

Mine's on the way to Willall now and part of the work is a mid pipe install- I know it'll be louder than stock but I hope it's not still too quiet afterwards.

Might have to look at other additions while it's over there...

    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂
