no drawbacks. The stock 2nd cats back probably start cutting into HP at about 550 to 600 HP, say 10 HP, by 750 probably 15 HP or more. 2 and 3/4 sections factory or aftermarket add 50 engine HP to the above numbers for flow issues vs HP loss; basically at that point the crush section and factory suitcase are removed and some 2 and 3/4 replacement stuff added. So just something to consider.
I'd coat the header and heat wrap the starter.
