my welder buddy says he can clear it on my 99si with no problem, is he full of **** or what, i have seen him do some sick ****, but am a little bit leary

 

It could be possible but you would most likely have to move your fans to the other side (pusher style) to make room.

For example, Full-Race makes a equal lenght mani now that is AC compatible and you can have 3 inch downpipe. They have pics on thier site. There is also the Hy-Tech style that puts turbo over the tranny so again 3 inch downpipe is possible.

Even with some log mani's it could be possible. A 2.5 to 3 transition after the ac can be done too..

 

THis guy made one so I'm sure if your welder buddy is as sick as you say he should have no problem.
