this basically the same as flowmaster 40 series? for a stock exhaust, it needs 2.25" inlet and outlet correct? both offset? before anyone says anything, this is for my moms mustang and she doesnt care about performance, just wants the mustang sound lol.

 

dont ebay mufflers. that will be falling apart in a year, just buy flowmaster

 

well there are some 40 series flowmaster mufflers on there too. i need to know if i need offset inlet/outlet and 2.25" or 2.5" to fit the stock pipes?

 

if you are having them put in by a shop...and you get 2.5" they will make sure it all fits and is welded in.

 

Yes you need offset/offset.

 

ok thanks for the help guys
