Yes, look at the last picture in the first post.
$90 each Magna flow cats
$90
$50 each Flex couples
$50
$80 7 premade stainless mandrel bends Cut from 2 summit "U's"
$50 5 O2 bungs
$30 stailess tube
$100 custom Water jet cut flanges, made from 5/8" stainless
$50 custom watrejet cut 3/16" copper gaskets
----------
$590 in parts alone, labor is another $150
I could sell it farther back but it will add due to I will have to have it re-made. If someone is going S&S headers this is the only way to go. Fleax couplers are a must! They eliminate the headers from getting all the vibration. This takes all the work out of the install. Just hook your tail pipe section to it and go. Keeps all the 02's for a obd2 car as well.

Ok I have a few more questions.
I have S&S headers fitted onto my oem precats I cut the flange off the stock manifold and welded it to the headers. Since I used no downpipe and the precats are bolted straight to the header my precat/pipes are VERY low right now, I measured 3 fingers from the ground
they drag on EVERY speed bump and larger road bumps, would this setup eliminate this?
Also I have 2.25 pipe, and yours is 2.5 I am slightly concerned about losing back pressure.

I would not be concerned about back pressure, you are still dumping this into 2.25" right?

I guess it depends on how low your car is. The cats are 4" thick and I have them mounted as high up in the pockets as i could get them. Without seeing your setup I cant say for sure. My car is really low and the cats are the lowest point and I have scraped them from time to time.
