Hey guys, I have a LS in my 1994 Civic Coupe, I was just wondering what kind of exhuast do I need to go with if I cant afford an aftermarket one? Ever since doing said swap, nothing lines up. One guy told me to get an Integra cat and that will solve everything but is there more to it? Also what is the stock piping on a Civic (92-95), Integra (94-01) and what would be the best size piping to use if I were to go to aftermarket catback? Thanks

 

If you're staying n/a then 2.25 inch piping will be fine. Stock is like 2 inches I believe.

Buy a catback for a Civic and have an exhaust shop weld the flanges together or have them custom make flanges on the piping for you.

 

yeah, i would take what you have to a muffler or welding shop and have them cut and match it up correctly, they will just add in a small piece of pipe or take out a small section, depending on what you need done.

 

or find someone on here who can weld and is willing to do it.

 

mad hatter on waters ave does a great job and has good prices.
stock size is 1 7/8
depending on your future plans go with 2 1/4 - 2 1/2

 

a civic coupe rear section will interchange with a 94+ Integra 4 door perfectly. The 2 door Integra rear section tip is very close to the bumper cover.

 

yeah, my type r muffler was a little recessed under my bumper cover.
