I'm about set to take the Random path but I'm wondering if they'll be compatible with some of the turbo kits that'll be out shortly. What is the pipe diameter on these cats? I noticed that for the Z32 twin turbo, Random offers various diameters (for example 2 1/2", 3", etc.) . It seems that a full 3" turbo-back exhaust configuration is the way to go for turbos.

 

Just got the RT Cats installed at Avalon, and WOW! The car is sic! With the Nismo exhaust, the car sounds and feels awesome! If I'm wrong to think that the car is now getting at least 300hp at the crank, then I don't want to be right.

Plus I installed the Insaneamine grounding kit, and the idle does feel smoother.

All a must have.

 

I'm next for this mod this week. I already have headers and dual. My question. Will this cause me to need a TS reflash; my switching cats? I want to confirm b4 I hit the place order button. I guess I could call TS but anyone have the short answer?

 

A ECU will help, but you will still see more HP(than stock) with out the ECU

 

How long can these highflo cats last?

 

I will most likely be the one to test that on the Z.

I have close to 1000 miles on mine in the last week. Actualy a bit more than that. They were in stalled at about 19900 miles. Ive had my Z since April so you get the idea of how much I drive.
