If I buy just the flowmaster 40 series mufflers for my 89' gt part # 42543 ( I have a cheap 2.5" dynomax now) will I have to do any work other than all bolt on work? Do I need anything extra or can I just switch the mufflers?
Thank You,
Joe
are the mufflers you have now bolted in or welded in? if bolted it it will be an easy swap but you will still need to weld in muffler hangers onto the new mufflers
