Ebay Header of Doom, Anyone Try this yet? Options

So we have a cracked exhaust manifold on the race car.... this along with, you know, sounding like a sewing machine around the track, we wanted to upgrade the exhaust. We found this gem here on the ebays.

Anyone had any experience with this bad boy?

i've had one on my geo for 3yrs now i think, i've beaten it pretty hard AND its heat wrapped. if it was crap i think it would have broken by now. i've romped full throttle keeping the engine 3000-5000 rpm through twisties repeatedly, ran it upto 100 on the highway a few times with the pedal to the floor, cruised at 80mph for hours on end, etc etc.





it rides a little close to the alt there and it was making the hood/engine bay pretty hot so i wrapped it up.







everything fit great (celi needs a pipe extended), the powerband shifted upwards a little. feels like its got the most power around 3500 now but feels stronger anywhere over 2000rpm and just starts to fall off at fuel cut.
