Wondering if anyone has switched from R/T's to Crawford cats. On another post can350z changed from the R/T's to LaBree's.

If so, how much of a difference in sound with the Crawford cats?

 

hey dave, so if you do change it out, how much would you sell them for? is the r/t's what caused your exhaust to scrape?

 

I think it was more of my driveway/eibach pro-kit. After installing the Nismo S-tune's, all is well

 

i just changed from rt to crawford cats because the rt
cat blew out.

you won't regret it. It's noticibly quieter.

Did you notice less of a rattle/rasp at 3.5-4K rpms with the Crawfords??

 

thanks for the info rob.

was it a bunch more quiet?

what about the buzz/rasp...any difference after going crawford?

The rt cats were a little rough (i guess raspy) at low RPMs
but I didn't mind because they flowed so well (in comparison
tests I've read about).

The crawford has a deep but smoother sound, even at lower
rpms. Now that my rt cats have blown (less than 1 year, 5k
miles), I'm more than happy with crawfords... hopefully that
also means more time on the road than in the shop...

enjoy,
rob

 

thanks rob

 

Dave,

Guess you'll be switching out the R/T eh?

I will be getting my installed soon. You're welcome to listen to them when they're installed.

 

Cool Frank, we can do a side by side sound test

 

Do you think you are getting the same power with the crawfords as the RT cats, I am considering both along with kinetix in third.

 

No crawford flow less than R/T cats. Kinetix has the lowest Flow out of these 2
