i am trying to adapt a k&n filter from a gmc 454 that has a 3.75" ID to a rusty's intake tube that has an OD of 3". i bought this filter on eGay for only $1.25 and wanted to finish this little project on the cheap. i could use a silicone intercooler reducer but i thought exhaust pipe would be much cheaper. only problem is an exhaust pipe reducer the has a 3.75" opening is an odd size. dont want to pay an exhaust shop to make it either.
anyone know of a great exhaust pipe supply site that has everything?
