Any B series guys running a bisi header? Managed to bolt up just fine no issues with innovative cross member. Had to unbolt the T wit hood latch for it to fit though. As for the radiator obviously half rad n gotta see how much farther I can slide it over cause it's rubbing. Just using brackets on the cross member so I can place it where need be.

Any1 else running a bisi? Only problem I see is once bolted in the collector seems to be pointing up. And yes I had the welds redone for u negative Nancy's against bisimoto lol. Just curious on others fitments who have/had ran them.

Pict of mock up on motor. Making sure I got everything set before swapping new motor in

 

It is possible that's what is causing the collector to point up.

 

Now that I think about it.. the header is 2 piece. Downpipe just slides on and has bolts hold it tight + tack welds for safety measures. Maybe I don't got it shoved in far enough but clearance with oil pan is amazing. Will snap a picture tmrw

 

Slid the rad over as much as i could. Might just wrap the 1 tube or top half of header since close to rad. As for bottom it's not pointing as high as I recall. Still has a slight angle up but can prob bolt it up. Just need a bigger test pipe. My 2.25 I don't think gonna work for a 3' dump lol
