Which turboback exhausts start with O2 housing being replaced?

[ssdragon]

Please list which exhausts that are called turbo back are true turbo back exhausts that come with a new bigger o2 housing and cat option for those of us that want to stay legal.

I was mainly wondering about G-Power, VRS, and Hahn Racecraft exhausts. I heard RNR was a good exhaust but I cant find a website for them.

This would be for a 1997 GSX Automatic for me.

Dang! $900 for the 3" SS O2 eliminator turboback!

G-Power is $300
Magnaflow SS twin-tip muffler is $54
Pair of Superior polished SS tips are $43
Muffler swap at a muffler shop is $???

$397 plus the muffler swap cost. Or you could keep the G-Power muffler and call it $300.

True, it's 2.5" until after the flex section, but that's a BIG price difference.
