High-flow cats?

[Guest INASNT]

If u r gonna be pumping over 300rwkw any cat is going to start to smell like rotten eggs after awhile.

Also it aint hard to clean the yellow stains off the back of the car, but u need to do it while the stains are still fresh orelse its a bitch to clean.

Merli, I could probably throw a few more names up, forgot to mention Nismo, BeeR, ATTKD, HRD etc...

Prices for GT-R sports cats can range from 40,000Yen to as high as 90,000Yen, which isn't cheap. I mentioned HRD because they are the only one I know who make up to 100mm Sports Cats...everyone else make either 70, 76.5, 80 and a few 90. So perhaps it maybe better to get one custom made if you want 4", but seriously I don't think you need to go that big.

I too have been looking in to this.  

 

Up until recently every 1 I spoke to in AUS said they cannot get 3.5" cats.

 

Exhaust Technology have recently told me they are now able to get 3.5" Cats and they definately make a huge difference when making upwards of 300rwkw and over.

 

They are $380 each.

 

They have a www site that is listed on the quote they gave me but it doesn't appear to be up at the moment? Maybe its a type on the receipt?!?

I always thought cats were measured in capacity. For example my cat's capacity is 7 litres with 3" flanges so it bolts onto my exhaust.
