I'm looking to put on hf cats on. I know the RT's are known for a raspy sound. Which cats have the least sound impact on the exhaust.

Thanks

 

Based on what I have read in other "Threads" and "Posts", asking same question, I decided to go with Kinetix High Flow Cats. The Kinetix Plenum has been installed and with a little help from FedEx, cats will arrive by next Thursday or Friday and be installed immediately. Kinetix currently has a fantastic package price for Plenum and Cats.

 

I could BARELY tell ANY difference in sound with my stock exhaust when I added my cats...

Stick with the company who made the original high-flows for the 350Z!!! More so brings only RACE INSPIRED parts...

Crawford's!!!!

I recommend the Labree Motorsports Cats. They make very noticable power gains and the sound is great. Very deep, never raspy.

 

Labrees website looks like they only have test pipes. How much are there cats?

Crawford's website is down, and Kinetix website doesn't want to take my order.

 

I'll chime in and say the Ultimate Racing ones - I added them and the Y ipe at the same time to my car (Apex'i Hybrid Megaphone exhaust), and acar is the same up till about 4500 as it was before, and literally just a touch louder from 4500 to redline....and the cats have a 5 year warranty

 

You know you were going to have to call Doug to order anyway!!!

 

The Labree's are $495 for polished stainless steel. I believe the cats are Carsound.

 

The exhaust & muffler does play a big part in the final equation; as I have the PE steel cats/Nismo headers/stock exhaust & muffler and the difference, if any, is hardly noticable at all. Will be changing the Y pipe/exhaust & muffler (on order); will see how it sounds then.

Ouch... kinda high for cats.
