can you guys explain to me what the advantage to making the change is? in the side by side pic above the new and old dont look all that differant except the bellow and material used. is it more of a heat retention thing? and is there much to gain doing these and manifolds vs just one of the 2? thanks just trying to learn.
Like i said the pics dont do the justice
The stockers have dents are flat in spots.....poor flow characteristics
And dont have the bling Is it better Ya,Will i gain a lot.......probably not,But everything helps.
