So I am in the market for a exhaust manifold to go along with the BBK B once it is released. With the price of the tubular manifolds, the lack of dyno results, and my want to not give up any torque I am shifting my focus to maybe porting the stock manifold. So...

BR porting with core = $275
MAP porting with core = $225(+$90 ceramic coating)
PPI ported with core = $75(just porting)

With the PPI I like the amount of options given. Honestly I would probably go all the way and have it ported the heat-sheild bosses machined off and swain tech coated which brings it up to $369, then the extreme porting is another $75. I like this option because it will not have the ugly manifold but also won't cost.....alot. Any input, suggestions, or if you have any of the above and some numbers to back it up would be great. Mods if I am not supposed to list prices please let me know I didn't think it was a problem though. Thanks in advance fot the input

That's what I'm thinking, but on the flip side all the way with PPI is gonna run me $444 should i try to find a used tubular? I still really want to keep the torque, I'm not just looking for a high hp number on a dyno.

i believe theres a thread for this, showing that MAP porting is superior than others. just my o2

Most "porting" Ive seen on manifolds is just polishing with very little material removed.
