  8. long tubs

    in Bolt On Performance

    Posted

    lets just say the shorties dont do anything that youd see on a dyno (at least compared to the stock LQ9 manifolds)... so your basically going to get the same gain as if you went from stock to long tubes lol. we typically see (on stock 6.0's) about 35-45 WHP with a tune + LT headers only (with cats and cat-back). thats a nice gain if you ask me!

     

    the pacesetter headers are the cheapest and by far the most popular amongst GM truck guys here, but are not stainless and do not survive so well up in northern areas especially places that salt the roads. getting them ceramic coated helps a lot but still, you get the idea. they also dont sell bolt-on mid pipes, so an exhaust shop will need to weld them in.

     

    then you have dynatech, which are also popular but pretty expensive... nice product though, and they offer 100% bolt-on kits with and without cats. OBX is also very popular, its basically a knock-off of the older dynatechs just much much less $$$. there are a few other sets of headers for the SSS but those are the most popular/sensible.

     

    also keep in mind if your under 500 WHP or so, i definitely would stick to the 1 3/4" primaries headers. they will work better for your TQ curve :thumbs: (all the above mentioned headers come 1 3/4")
