Default Need Some Help Please

so i went to track last night and ran a respectable 12.6 with my 99s 1.78 60ft
problem is i went to track with electric cutouts and was told i cant run,i new the guy doing inspection and he made me promise not to open.anyone know why no cutouts.the car pushes 405 rwhp with cutouts open. with cutoout closed i ran the 12.6 through STOCK MUFFLER anyone guess the horspower loss from open to not with stock muffler.and if car was tuned to open exaust when i put a new muffler on should car be retuned. what would be best muffler to go with? and with proper tune can i get that horspower back.
It would be great if anyone can help.sorry for all the questions


P.S. i dont recommend 16inch m/t et streets with 275.40r17 on front.
car was all over strip.my driving pattern was one big s the car was all over the place i almost lost it at 100 anyone running the et street with non skinnies on front?
