They look fine! I notice it only does it with my cutouts closed but when there open it wont do it! Car drives fine it only backfired at Wot and cutouts closed!

Well some more details might help but backfiring is generally caused by an overly rich mixture, so check all ignition components for possible misfire culprits.

Maybe its excessive backpressure on the valvesprings and also or u speed density tuned or with a maf if the car run fine with the cutouts open it must have been tuned that way but when they are closed it could be messing with fuel trims etc.
