GS Motorsports has been working on the 6.1 as everyone knows, now we have Teamed up with a Premier MFG for an excluslive production piece on the 6.1 Big Tube Headers
These are Long tube all stainless Headers with cerma chrome coating.
They feature a 1.7/8" primary tube for the Supercharged cars and we also have a 1.3/4" primary tube for the naturaly aspriated 6.1 Packages.
These headers feature equal length tubing and a 3" collector
We will have more info posted and dyno sheets saturday.
On a side note the port difference on the 6.1 is dramaticaly different so just bolting on a 5.7 header will not be a option on the 6.1 packages from GSM
