Louder...RT cats or Crawford cats

Traditionally higher flow = louder.
After seeing the flow chart, the test pipes flowed the best... obviously... the RTs, and then the Crawfords.
Honestly, just adding the cats to a stock exhaust... I didn't feel changed it THAT much.

Let me tell say . . .I am running stock exhaust with our headers and cats. It is noticeably louder, not raspy at all, just louder. I really realized it again now that I took my JWT off and put the stock air box back on. I am pretty sure that the sound difference is the cats because we did Doug’s new car in stages and the cats were added a couple weeks after the headers. The cats really opened up the sound of the car. I also let JAG drive my car this weekend and he commented that it sounded great and he is used to a 100% stock car.
Now we will see how my exhaust will sound later this week when it gets here. I hope it sounds incredible.

Why did you remove your POPCharger? What exhaust did you chose? Talked to Doug today, my cats are on the way.
Peace!

I am keeping the exhaust on the DL for now, but as soon as it is on I will post up.

I also read that guys with the RT's and stock exhaust have very little change in sound.
The Nismo cat-back and RT combo is LOUD imo.
Was just wondering if the Crawfords would be a tad bit softer than the RT's.

I can vouch for what VandyZ said-- after driving his car, his sounds NOTICABLY different from ours. Notice I say different, not worse or anything like that. I like the sound of his, and imo, there is no rasp in it. I think it sounds really nice, and was surprised that it sounded that different still with a stock exhaust.

Same here - stock exhausts with the R/Ts. Much louder sound at full throttle. Combined with the PopCharger - really sweet! As someone in this thread noted, however, the R/Ts look like test pipes with a bulge. Anyone know whether the small amount of catalyst inside will cease to function after a few years and result in a lot of CELs? I noticed that R/T only warrants the emissions output for two years.

Wow, interesting. I'd be very interested to hear more on this info. I'd be a bit hesitant to purchase cats that I'd have to replace in 2 years.
As far as the Crawford cat's longevity, we could probably find out if we knew manufacturer of the core of the unit. Doesn't Crawford just buy the cat core from a big name cat maker and then do a 350Z specific pipe fitment around it? Perhaps this is how most companies do it?

I so wanna get those RT cats. I'm just a little hesitant because it sounds like some people are having fitting issues. Overall, it comes down to this...
