Here is what people are saying about these headers: 

"Right outta the box power was great, retune even better" 

"Ground clearance wasnt affected everything tucks up nice and tight underneath but still plenty of clearance around everything so no ratlles or melted wires etc." 

"The brushed finish is beautiful. The beveled flanges are awesome as no more bloody knuckles. The v-bands are so easy to use, the 1 peice x-pipe made installation fast and simple. I did the install by myself no one around to hold anything up for me still was a cake walk." 

"The headers just slid right into place no removing the starter or anything silly like some other brands. I'm very happy to say we will certainly be carrying these headers as soon as they hit the market."

"These headers are beautiful!! Like all of Pfadts products the quality is 2nd to none!!"

"very happy with the results.. made 424hp and 434 tq… " (2012 Corvette Grand Sport, 381hp/387lb-ft baseline) 

And a deeper analysis of the tuning potential:
"The Pfadts did make more power over the entire band" (than the competitors 4-into-1, 1 7/8" headers)... "Tuning wise the Pfadts made nearly the same power/tq from low 12 A/F to 12.8, where as to get the numbers even close I had to lean out the (competitor's 4 into 1 headers) to over 12.6. My first few pulls were in the low teens with the (competitor's 4 into 1 headers) when it was in the low 12's A/F to begin with. I felt like I had to work to get the (competitor's 4 into 1 headers) to where they ended up, but the Pfadts could be left more "road race conservative" tuning wise and still make the power and tq. Over all I'm very impressed."
