so if i buy a greddy sp-2 cat back exhaust for my civic will it just bolt on? is there a difference in pipe sizing and will i have to get a hi flow cat. i have a 93 ej1 which is coupe.

 

As long as you haven't changed anything and the stock exhaust is on there now, then the answer is yes, it will bolt right up with no problems.

 

a "CATBACK" will bolt up flawlessly to your Catalytic converter. Installation may be hampered by very rusted bolts, due to the daily fluctuation between air temperature and operation temperature. This wide range of stress rust's up the flange bolts, often beyond recognition.

Despite rusted bolts, the kit you get will come with all new ones, so dont worry about breaking the old ones in the process of their removal.

 

Cut-off wheel FTW

 

thanks very helpful ht ftw

 

Bolts right up dudeeee. Good exhaust choice by the way
