change exhaust

[mustang0386]

could i change my bolt on cat back system with out doin any welding?i want to put on a x-pipe if its possibly? and do i need to have the cats on it?

if you put an X pipe on then you can bolt up an exhaust system cat back thats deisgned to bolt up to the X pipe with out having to do any welding. Its not super hard putting on an X pipe but it wont be all fun and games either. You dont HAVE to have cats but most shops wont put an off road x pipe on a car (no cats) cuz its illegal (some states just dont care)

well i got already a flowmaster force 2 on my car that is catback. and is it better to have a x-pipe.
