I did like them. I wish I kept them a little longer and tried them out a bit more. When I revved them high there was a bad tinny buzzing sound in them so I took em right off but got me wondering after if maybe it was just the muffler buzzing on the pipe , or possibly if putting the dynomax race minis in front would eliminate that sound if I were to use them. Wish I tried that. They were a little louder than I wanted though which was surprising because I’ve used them in the past on different cars and they weren’t loud muffs. The long 3” x pipe does some funny things though.
Just a factory GM ls7 cam , I believe it’s PN 12638426. It’s extremely close in specs to the factory ls9 cam. The ls9 cam would probably be a little better for boost (tighter LSA by like 1 degree) but I really don’t think there would be a noticeable difference between either since the specs are so close
24249 (stainless mini race bullets). Didn’t change things too much but just made for a slightly better tone IMO when I put them just before the borla pro xs’s.
They’re from Ultimate Headers sold through a company called 3 pedals. They’re by far the best fitting header I’ve found for an ls swapped b body using kds engine mounts.
Really like the Dynomax + ProXS sound. Thanks for sharing all the different combos. I just ordered a set of ProXS for my 95 Caprice
Dynomax ultra flo sound nice !!!!!!!
