So i built the catback with dynomax ipipe and over axle pipe, Hooker Maxflow 3" in 3"out and did the rest, i still need to get a turn down mounted up but who cares for right now. here you go. The DynoHookerMax.
The catback sounds great at higher and lower rpms. No drone cruising at 80 its almost like stock with a little tone. at 3000rpm the sound increases dramatically. I'm interested to see if this breaks in at all sound wise. Anyway here are the pics and a vid. Overall. very happy.

Sounds decent. Are you just mounting the turn down right at the end of the muffler? I was thinking about doing that because I hate the way my car looks with the magnaflow single tips. I wasn't sure how good of an idea it was to run two turndowns out of the muffler, but I guess its not a bad idea.

yea, im just gonna do a 90* bend off the muffler and have a turn down towards the back. I love my car even more now with a catback. Also this was super cheap too and definitely freed some restriction giving a little power.

It looks like you used the center/offset Maxflow version. Correct?
Are the Dynomax I-pipe and over-axle pipe sold separately, or is that from an existing catback?
It seems like this set-up flows well, sounds good, is reasonably quiet, and is relatively lightweight.

That is one great sounding inexpensive catback. All you need is a little more 3" pipe for the tailpipe and turndown. Maybe $20. Total $200.
I'm really tempted to experiment with this set-up vs. my GMMG. The single turndown would look good on my Formula, too - or a Z28 like yours.
