irishson101 Posted June 14, 2009 Share Posted June 14, 2009 I am looking at some aftermarket CAT back exhausts for my Accord, and most of them are 2.5", while I think my stock cat is 2". Do I need any kind of adapter to fit the two, or will they just fit, or will I need a highflow CAT? I am new to this so any help is appreciated. Thanks.

Staninator Posted June 17, 2009 Share Posted June 17, 2009 It should fit if it is made for your year of accord. Just make sure you buy a new gasket for the cat and take the old one off. You can get one from your dealership for a decent price. Link to comment Share on other sites More sharing options...
