After being pulled over on the weekend, reality has set in. My car is simply too loud. Some of this could be because of the exhasut leak i currently have, but even still it requires attention.

My RB20 has a 3" HKS Hyper exhaust, running a muffler/resinator/cat. Looking at the exhasut tip it would seem the HKS muffler can take one of those diffusers/baffles whatever they are called.

Im hoping they make a dramatic difference to exhasut noise, i dont really care about performance, i just want a cheap and easy way to quiten the old girl up.

Anyone had experience with running one of these baffles in the Hyper exhaust????

No, just came clean and mentioned that i was aware that its a little on the loud side, mentioned that the car was coming in for some servicing in the next week, ie fix exhaust leak, new tyres etc etc. Was only driving when i had to until i got it all fixed.

I think a clean driving record does wonders in these situations.

Roy, the joeys that go in the back of the exhaust make a pretty big difference - quieten things right down to a purr. That was on a mates supra with an N1 exhaust anyways, so I would expect the same.

D1 Garage have one (or two) second hand ones sitting on their shelf at the moment, I dont know how much they want for them, but I dont think it would be huge.

Well i have a cat back HKS system, it has a nice but a softish note, not too loud...

i am currently thinking about getting custom dump, 3 inch pipe to cat and a 3 inch high flow cat...

is anyone able to tell me if this will make it too loud? As the car is everyday driver i do not want it over the limit.

Im thinking new turbo has a lot to do with it. Aftermarket turbo setups arent really designed to be quiet.:D

Oh well its worth it when i hit boost, the TD06 has more grunt at 8 psi then my old turbo at 15psi.:)

... but just need to tame it for the street, i dont car if those baffles drop power below stock as i drive lke an old lady on the street... for that matter on the track as well:rolleyes:

    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
