Its pretty easy once you get the hang of it,my uncle who used to work on raditors in chicago,tought me and he lets me use his welder all the time,we just finished instaling my dads exhaust...he now has a real quiet diesel. Or just cut one in half and weld them on the pipes...they dont even check here in cali(on older cars) they just check the db's with this lil'tester they have.
I have the flowtech mav/comet headers, 2.5 pipe to the X 2.5 to the 40 series flowbastards, 2.250 pipes fromt he muffs to the tailpipes I don't have the flowbastard drone to badly and it's faster with the pipe then without (almost a 1/4second faster no less) I miss my terminators.. they sounded a lot better till they rotted out.. as for you cherry boob...errrr bombs remove the damned things and find a set of the short case dynomax turbo muffs and run tailpipes be a lot quieter and a lot better sounding (cherry bombs suck) I'd run longer mufflers but we don't have the room for bigger cases so we have louder cars.. altho they have that new x=piped muffler could update mine and take the frankenpipe off the drivers side and run both out the passenger side.. food for thought
