oh yeah i called them they told me they didn't have flowmaster 40 series they said something like thrushmaster or something they can do the whole job for 350 which is cheap as hell.. i asked a few other places about what i want flowmaster 40 series with the h pipe and it varies mainly 550-600.. I talked to a guy at a shop that sells muscle car parts, and he told me unless im really into the performance it's not a huge issue not having the h pipe he said im gaining performance just putting on the 40 series so no worries and he said it should still sound great , running straight back from the manifolds to the 40 series... im getting it all done this week or next, probably next because i have that weekend off.
