I have the cat-back on mine running through the stock cat and downpipe. It's not really loud, but it is noticeably louder than stock. It's even loud at idle. Since I daily drive my car, my wife forced me to put in the silencer. Now, it's just slightly louder than stock, but it did get noticeably slower (back pressure). I do like the quality of the piece and mine kind of comes out at an angle, but it's a true straight through design.
Here is a sound clip of a B&B Downpipe, testpipe, and helix catback with cams:

On the bright side it does come with a silencer!

I don't mind it sticking out to far.. Infact I'm happy because my old exhaust which was an HKS did not stick to far infact it was barely out and it was high so that means it burned the bumper... My car also is running a bit rich so that means with the exhaust sticking out a bit mean less chances of the rear bumper getting black quicker.......
Anyway thanks for the advice.

Couple of things:
1) Is the Helix easy to install? Is there any welding? Borla cat back is weld free...
2) If the helix is the megan racing one does that mean to have to drill a O2 bung sensor hole... I heard that it is a bit of a pain in the butt....
