V36 370gt exhaust system/ cats

[acesofspades31]

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.

Jesus Christ!  Stay away from Autobahn and whatever the hell a "regen" is....if that's what they think will "fix" it.

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.

What the actual f**k is a cat regen ?

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

"Regenerate cats" LOL
So they're going to take it out and bash the insides, and charge you for it? Cancel that appointment.

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.

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

That's definitely the plan, I'm loving the 370gt and think I'm gonna keep for a couple more years.

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.

So in other words, he's going to get a steel pipe, hammer and gut the contents.

The guy is so full of manure, he could fertilize a farm.

[niZmO_Man]

Maybe he has a special spray can, which he picked up from a hardware store, called "silver spray" ?
