I got bored with my stock exhaust, so before I decide to spend 5k on it, I took out the cats on the stock exhaust, the response is much much more quicker. No drone, inside the cabin its noise is about the same as the stock with cats, but with turbo whistle. I don't have CEL yet, but am getting the o2 bungs made to solve potential issued. Overall, am 8/10 happy... I really need to hear other exhausts to decide wether to change it or not...
I've only heard SpeedArt, and to me, I'd be happier with my stock exhaust and no cats.

Cargraphic for deeper sound, Tubi for higher pitch. CG will give you better back pressure relief (faster Turbo spool and more power) but Tubi has less resonance on the freeway. Both are very good though.
Are you saying that Tubi even tho lesss resonance than the others, still may have more 50-55 mph resonance than factory? What about engine service light with Tubi, any problem with that??
Why would you be happier with stock over SpaadART?
Its SpeedArt, anyway, yes, am happier with the stock ones with no cats. To me I can't really tell the difference between the switch modes in terms of sound. The power, the SpeedArt may have edged it, but not by much and my friend spent 8k on it to get it over here. No thanks and my stock with no cats sounds better (to me anyway) in my case I think thats all it matters. I have already modded my exhaust again, and this time, without a doubt its very explosive.

In my experience the Tubi has very little resonance at highway speeds. Keep something very important in mind, however. There is a distinct difference between volume and resonance. The volume level of the Tubi will be higher then stock, yes. But resonance (or that annoying deep drone that resonates in the cabin at certain rpm's) is not present in my experience.

What about engine light...I guess no mention meant no problem with your Tubi exhaust??

The Tubi Race system has no cats, but uses O2 simulators to insure that there are no check engine light issues. In the cars we've done recently the check engine light has not come on with any of them.
Where are you located in Florida?

Pensacola....Know of a turbo with Tubi close by? I would like to hear one before purchase.

Unfortunately no. The closest I know of is in Sarasota, but that's probably a good 10 hour drive I'd guess.
In all honesty, I have yet to find someone who was not completely thrilled by the sound of the Tubi Race system. The sound is truly unique, the construction and quality is second to none, and fit/finish is top notch.
