Catback exhaust and ground clearance

Ive been looking at cat back exhausts lately and basically it comes down to either the ae or the vanguard.
However what Im worried about is ground clearance, I have to drive to places where there are speed bumps and if I even on my stock sport suspension, I sometimes hear the underneath slightly rub. Now with a catback exhaust Im affraid that it will hang down lower and potentially rub??
I saw pictures of the vanguard exhaust and it looks really low to the ground, have any of you guys with exhaust, wehter it be ae vanguard or any other system, had any problems with clearance?
Thank you

I have an AE and the car is on Koni/HR's (1.3 inches lower than sport). I've never had a ground clearance issue.

Thank you, by the way how do you like the ae? Is it a big difference over stock if I dont get catless downpipes?

I have Vanguard and I'm pretty low on my coilovers haha. I rub against speed bumps and road bumps if I'm not very careful. But this happened with the stock exhaust as well. It's more of a factor of lowering.

Does the vanguard hang down very low?
In the pictures online it seems that way..

Check out our exhaust sytem. We tuck it up in the tunnel tighter then any other exhaust manufacturer. We have pictures on our website that shows it. Plus for the price it's hard to beat!

Here is a video showing the ground clearance

It's a huge difference over stock, 40 lbs less! I know you were referring to the sound. It's very aggressive up top and tame down low, I love it. Some think it's too quiet, but fits my tastes nicely. You are not going to feel any power increase, but dyno'd to give 12-15hp on stock turbos + tune. Now that I have upgraded turbos, I'm sure there is going to be even more power gained.
