i am running a y pipe to a 4" mufflex with a spintech muffler. i hate to cut up my piping. i was thinking of installing (TWO) bullets on the tailpipes and use some aftermarket tips, as i dont wanna mess up the mufflex ones.

my question is, will it change the sound of the car any if i do it after the muffler, rather before the muffler as usual?

id like to make it a lil less noisy, both inside and out.

thanks!
