anybody have any opinion on the APR exhaust for the S4? can't decide between MTM and APR....

I've heard both.....
for the money the APR exhaust/ stage 2+ cant be beat, but it is loud. The mtm is dead quiet, though the tips stick out to far and the Stage III upgrade costs significantly more than the APR.

We have a stealth system about to be released--
It will hit the shelf soon and will be dead silent. We expect to release info very soon. At that time there will be 2 versions available, a stealth and our SRT system. Feel free to give us a ring.
Thanks
