Bob,

When I get to the dyno in early June we'll find out if the DynoMaxs' had any effect on AFR with my car. The SW Xpipe did lean things out a bit
after replacing the MFlow resonator with it. AFR went from about 13 up to 13.4. Bringing AFR back down gained about 15hp. No gain in bumping timing past 29d.

Thank you Andrew!

First time I called to order a 3" X pipe they said no,
have to buy entire system and/or trade in the resonator.
Next call, I got my B&B X pipe. Not cheap....
The SW X pipe to me was $278 a couple years ago. The B&B is essentially the same. How much for their X??

I've installed just the fusion exhaust but haven't decided where I want to mount the vacuum reservoir and switch plate.

I think I would like to put it forward left in the engine compartment where the AIR pump once was - plenty of space there.

But does it makes sense to have the reservoir so far from the actuators.... or would it really not matter with vacuum?

Any help here would be greatly appreciated!
There is space to mount the plate behind the rear license plate and also inside the left rear fender. Steve put his behind the rear plate and it worked out rather well. I can't really see the point in going to the front of the car and then all the way to the back.

Concur thats the only thing I dislike about this mod. Stone city

Digging up this old thread. I'm installing this on my car and am not getting a 12V output from the little black box. I verified there is 12V on the input (red) wire with the ignition on; and the black wire is grounded. I'm wondering if the little box is just bad. I can't think of a way to test it.

Also, wondering how your exhausts are holding up. Are the valves and electronics still functioning well?
