Other Group Buys from Trailblazer SS forum (Read the original posts from the guy who toured the shop and set up this group buy) (***Remember this was only with a 2yr warranty in mid 2009 so prices were different)
Quoted from that thread:
"Thicker butterfly plate and better seal. As a test he actually dumped water into the cutout and I did not see it drip a drop. He said it would leak by eventually but the fact you could pour water in it is a testament to the fit if nothing else.
The Y-pipes look 10 times better than the DMH. I had to tweak one of the bolts on mine to even get the cutout to slide on. The tolerances on this stuff is a lot better. Very apparent when you see it.
As far as the gearmotor its impossible for me to speak of longevity as only time will tell. But they were well sealed. As a matter of fact all his harness stuff looked really good.
After talking to him a bit you could tell he strives to make a better product. I honestly dont know how he does it so inexpensively as the outlay for the CNC machine alone had to be substantial.
It really is nice stuff. If you read my post above I was skeptical and had every intention of going there and beating him up !
Above all that he had a multitude of valves/Y options. It wasnt a one size fits all deal."
***Also the only negative info I could find on Badlandz HPE was from a Subaru Forum from a purchase in 2006.
FROM BADLANDZ WEBSITE:
THEY ARE NOT INTENDED TO BE OPENED AND CLOSED UNDER ANY DRIVING CONDITIONS OR HIGH RPMS. THE RESULT WILL BE GEAR MOTOR DAMAGE WITH EXHAUST LEAKS AND A "RATTLING" SOUND COMING FROM THE EXHAUST CUTOUT. FAILURE TO OPEN OR CLOSE WITH ENGINE OFF OR AT ENGINE IDLE WILL VOID THE WARRANTY.
Only use at idle or in neutral....Not Wide Open Throttle...
