So if I had a stillen cai I'd be even worse off because its 2.35" ID through and through? If I did change it I'd have to be tuned and change it at the tuner since itd be undrivable there. It's a lot of work for possibly little gain. I'd just need ID pipe bigger than then the TB no? I have that all but at the MAF which is about 5", a section that's about 8", a section that's about 5" and a section that's 2.5".

if you say so...


it all has to work together at the end.
I say you are still leaving some power under the table.


im not saying this to be mean ,, just from experience & learning from others

Well picture this, I thought of flow too...

Stillen 2.35" through and through, smooth flow.

Mine 2.5" then 2.35" then 2.5" then 2.35" etc, a little bumpy even though I knife edged the 2.35" sections on both sides.

Possible new cai, 2.5" ID sections where silicon is, then new sections of 2.75" OD. Now I'm not sure of the ID on the 2.75" OD pipe (2.63" i think, 0.11 wall) but I'll have to stretch the silicon sections at the connections. This will make the flow also bumpy as the silicon will be smooth, then open up larger than 2.75", then the air will hit the knife edge of the 2.75" OD pipe. While that's the most cubic inches in size, it'll probably be the least free flowing.

in case you didnt get that i mean this...while id have all sections now bigger than the TB opening, wouldnt this hurt flow some?
