anyone running sidepipes?

ok bud...i'm looking to get an 80" set for my rumble bee..yes..you heard me the bee..i've gotten bashed a lot about it...the inlet is 2" on the patriots...the firts 2-3 inchs...i was thinkin' i could get a welder to just got that part off and make where the 3" starts an inlet....the only prob i have with mine (that i will be gettin, i don't have yet) is that the pipes go down to 1 5/8" (the glasspack part..so i'm alos thinkin of replacin' the packs with straight pipe...just hope it ain't too loud... when you gettim' good luck and definitley post some sound clips and pm me with details...depenedin' on how much room you hae for install..i was also thinkin' that a flex-pipe might help with bend and engine ovement..someone please correct me if that's a bad idea... but i hope this helps some...the dynomax sideliners..they have a 2 1/4" inlet..but just as bad bc they go down to ! 3/4"..1 5/8" bc of it's glasspack muffler too...please keep me updated on you progress..thanks..
