VRSF Catted DP?

Anyone using the catted DP from VRSF?

Can't go catless here in NC - visual inspections, not just tailpipe sniff.

Nope, sorry - catless. No inspections and didn't want to spend the extra $$$. Don't the high flow catted versions have the risk of failing the sniff test on top of throwing codes anyway?

Hmmm, shouldn't fail the sniff - not sure about throwing codes. That's part of why I'm asking.

I think you have it a bit backwards actually.

That's standard. I don't know of any state that doesn't have a visual inspection. However, hardly any states sniff, that's why you can get away with a catless DP.

The visual inspection, usually, doesn't result in an inspector either seeing, or caring, about a catless DP...especially when the rest of the exhaust looks stock, including secondary cats/resonators.

In NC, if you don't throw a CEL with the readiness completed, you're good-to-go...outside of a cowboy inspector looking closely and giving you a hard time.

Hmmm, it would appear you're right, no sniff test. I would have sworn I read they did sniff tests when we moved here back in '07 and I've (obviously) never actually watched any of the guys do the actual inspection. Just an OBD "emissions check" according to the NCDOT website.

Florida and Tennessee don't have any inspections for sure - Just FYI. It's good and bad.

Yeah, I grew up in MI - the land of the Big 3 - so the whole inspection/emissions check every year was a rude awakening.

I ran a catless turbo-back exhaust on my STi back home, but not sure what I want to do with the X1.

In my experience the catless DP with stock exhaust really doesn't drone. It has more growl on startup, and I don't notice extra noise cruising on the highway. I need to find someone to record while I do some drive-bys but I haven't had time.

As posted above, no drone. Stock resonator and secondary cats still in there keeping it civil.

A bit louder on startup, and quite nice sounding pulling away when standing outside the car (like quiet but you know somethings up...). Inside the car is like 99% stock.
