Hey guys,

I have 2008 v36 370gt. Everytime the car is turned on and is idling I hear a rattling sound. Took it a mechanic and was told the cats are nearly done - got a quote from Nissan for $2000 per cat lol. For a second opinion took it to Autobahn here in Perth, and I was advised that they can "regenerate" cats and it would stop rattling. I've booked the appointment for Regen early next year. I personally think I'll have no luck with the regen so now I am starting to look for a plan b. Would it advisable to change the whole exhaust system and this would take care of the rattling sound? If yes, what would be a nice exhaust system that is not too obnoxious (as I use my car as my everyday) but can roar on higher revs when needed [emoji23]

Also, folks from Western Australia, any recommendations for a good shop I could go to?

Thanks in advance.

Hey man,

 

Similar issue about 6 months ago on my 370gt coupe. Rattling etc
Nissan quotes $1193.45 For one.. Lol

 

I went HFC ($600 installed) But have since just swapped to 370z cats ($200 plus $100 to install)
Keep an eye out for 370z cats or just go hfc :)

Super Cat Converters in wangara sell them they are a wholesaler who supply to exhaust shops.

Much appreciate the valuable advice. Will look into HFCs and give the Super Cat converters in Wangara a shout and see what they say. I've checked their website and they do installations as well. This is my first Japanese import vehicle so not too sure where to source quality mechanics and part suppliers. Any suggestions for good mechanics/mod shops and tuners in the greater Perth region?

Thanks mate, I will definitely go for HFC. Are you in the eastern States? Prices in WA are a bit more than the eastern States. The local Nissan dealership in Perth quoted $2k per cat lol
Dude, buy a set of high flow aftermarket cats. You don't "regenerate" or rebuild cats. You replace them. Don't be tight about it.
That's definitely the plan, I'm loving the 370gt and think I'm gonna keep for a couple more years.
What the actual f**k is a cat regen ?
So the dude at my local Autobahn told me that he's gonna somehow regenerate the elements in the cat converter which I found surprising coz if the compounds run out, the simple answer would be to replace them and he was adamant to "Regen" first prior to replacing them.

HFC all the way. Have a look at Fast Intensions or Stillen. I have a pair of second hand Stillen ones if you are interested.

Thanks mate, you in Perth?

Yea I am, down at Success

    • I mean it's probably likely that people overestimate their skills in dialling in a setup and noticing the changes. I had SK shocks and springs, and added heavier springs and got them revalved by Sydney Shocks to suit based upon what I told them I wanted the car to handle like. I got back a completely different feeling set of shocks, which probably (?) feel great on track but holy hell are they rough on tram tracks and the like. The shock dyno actually looks pretty similar to Shockworks (from what I can surmise from a screenshot of a youtube video - and my dyno printout...) Truth be told I doubt I'd be any faster or slower with either setup, or camber/castor combination. I also had whiteline eccentric castor bushes up front of my R34. I removed them and put in poly non-adjustable ones to soothe my OCD (nobody ever set the castor the same side to side, and it'd be near impossible to do) and be happy the wheel is centered in the well now for clearance reasons. Yes I wanted it to move 1mm 'back' :p I've effectively set my castor back to stock, negating all the benefits of that which is supposedly massive. I've probably also altered toe and camber in a negative (detrimental) way. I can't tell any difference steering the car.
    • You reckon? I have to disagree. Notwithstanding that at some point we may all be forced to do this to our cars if we want to keep driving them, there is absolutely nothing about an electric-converted-previously-IC-car that is ever good. EVs that are built by OEMs on platforms that were originally IC already suck, let alone the shitty outcomes that result from doing it as a retro to something that was actually built as an IC car. This is because the platform really needs to be designed to house the battery in a useful place (ie, down as low as possible) and the motors are properly located relative to the wheels that they have to drive. Converted platforms already suck at this. But when you try to shove sufficient battery capacity into a previously IC car, you can't put it down on/in the floor, because that space doesn't exist. You can't find enough space where the fuel tank used to be (if it is an inboard fuel tank) and you don't want to hang it out behind the rear axle line if you had a rear fuel tank. And there's not enough space in the tunnel if you still want to use it for anything remotely like what it was originally used for. The engine bay is too big for a motor, and you'd really prefer that the motor for the rear wheels wasn't in the front engine bay anyway. And there's not enough room where the diff was for a proper man-sized E motor. And then.... there is the complete lack of soul and emotion that is provided by EVs. There are some cracking restomods out there. Like the Alfaholics GTA thingo. But it is petrol powered. Look at the alternative EV version of a GTA restomod by Totem. it is jaw droppingly beautiful. But by all reports is is objectively awful to drive, despite having 600 HP or something, simply because there is nothing there. It sounds like a sewing machine or a leaf blower. It should scream and wail and make the hairs on your neck stand up. Oh, and it's 1500 bloody kg in a car that was <900kg when new. GTRs are heavy enough as it is without pushing them up to 2tonnes worth of pork.

    • hahaha @joshuaho96 the most action it gets is when I have to drive from West to SE VIC to meet the fam. Even then, it;s on highway cruising speeds
    • don't know anyone in this thread, but i just found it, read the entire thing in a few hours, realized greg is still posting progress, and just have to say, this is awesome. it looks awesome. 100% right about the Uras kit making it a pain to get on hoists...have the same kit on my 34 and it takes six 2x4s and race ramps to do it without taking parts off. this reminds me exactly of this thread. https://grassrootsmotorsports.com/forum/build-projects-and-project-cars/r63-amg-the-unicorn-of-my-destruction/110824/page8/
