Well, it is not a huge deal, but you just need to have one on either pipe. Are you placing the turbo center or offset to one side or the other?

I like that car thanks for the pictures. Is that wastegate lower than the k member??? Looks like your running o2s. ? Or those the wideband bungs.

I'm going to probably offset it to the drivers side and have the 5" exhaust out the fender

The wastegate is just above the K-membere. Those are o2 bungs.

I'm going to dump mine out of the driver fender for now aswell.

I would say if it is offset, just try to get them close to equally spaced from the collectors. If it were center, you could mount them both right before the flange on either side.

I'd like to center it but with this Turbo being pretty big space is an issue also the intake pipe is in the middle making it more tough

Should be ok but I haven't had the car running hard enough to open them yet. Need to add the intercooler and to tune it first.
