This option for the Pontiac crowd is a game changer since most Turbo systems need lots of welding which can be expensive if you dont know how to or know someone who can weld. We are in the middle of a Group purchase for the Round Ports /Ram Air V headers and Stainless Headers is going to make the flanges for a D-Port header. The D-Ports are a tricky design due to the D Ports being so close together... The method they plan to use to get around that is to use one larger Tube that covers both D ports. Check out the details to the Boosted section in the link JC455 provided if interested. We have two list going right now... We have a Round Port /Ram Air V head list and a D-Port list... The more we add to the list the greater the discount becomes. SPEED SAFE, NICK

What's the secret with V-band clamps? My experience is that once installed, I break the stud when trying to get them loose again. The stainless nut seizes to the stainless stud.

I have never had an issue with V-bands. The entire exhaust system on my C6 Grand Sport Corvette has V-bands and I have had that exhaust out a couple times with out any issues, they are stainless. Is it possible someone over torqued your V-Band bolts? They dont need a whole lot of torque, snugged down is how I do them.
I have used them on several vehicles and never seen them fail or have difficulty being removed. As I mentioned above, they are literally leak proof once installed. You could apply a solid film lubricant or even ant-seize to the threads however at those temps I dont see it holding up long at all. SPEED SAFE, NICK

S.S.
I come against SS fasteners all the time,
Exposed to constant heat and cool cycle SS will NOT come. apart it will galll up and break or strip. |

BRILLIANT that may be!
My EXH band clamps seem fine...becaue the rear Main Seal protects them. Try Anti-sieze paste? |
