Default Very nice! Maybe you should think about wrapping the motors w/ some thermal tape for longevity....
That's some serious heat between the dp's & cats.

Default Tracking...... Hmm I can put those where my test pipes lie or I can
put my cats back in. Need to see a video or sound clip.

Default i am going to sacramento raceway soon and will post my results from the track, i also did some gtech
runs and on those i picked up 2/10s of a second off my quarter mile times from closed to open. but i am really interested to see what they will do at the track.

Default you will not lose any power at all ever with them open
a turbo motor will never lose anything from a more free flowing setup after the turbo. EVER

done deal, end of discussion

Default Yup. Turbos run on pressure differential...you want high pressure in and low pressure out
Best way to ensure the lowest pressure out is to have the hotside vent directly to the atmosphere....

I run a DMH cut-out after the cat, in place of a cat-back system. Flows better, and quiet for work.
