The "Y Pipes" are necessary to weld the 4.6 tips to my existing 3.0 exhaust properly...tips are WAYYY to wide to just weld to existing pipe... don't know if that size discrepancy exists with a 4.4 like yours... not a question of growl (were you thinkin' I was referrin' to X pipes?!)
Thanks for the help tho !!
