    90 prelude si catback exhaust?

    Will a 90 prelude si cat back hang on a cb7 with stock hangers? My buddy has one he will trade me for my stock exhaust. This one I'm getting is 2.25" inside dia. If it wont ill just hack off the stock muffler and swap it with my ractive. Cannon muffler. Just thought I would ask before I get too far into this project.

    The entire catback won't fit perfectly, no.

      K so I'm better off just hacking off the stock muffler and welding on my muffler. I'm adding a 27" glasspack so it has a nice deep tone to it. Eventually down the road ill be getting a header and downpipe for it. Ty for the anwser

        Not sure if that will solve your issue. The Prelude and Accord are different cars, it still might not bend in the right places from the cat back, regardless of what muffler you have on there.

          Are you going for sound only? If so, then hacking off the stock muffler and welding an aftermarket piece to the stock piping will be fine. However, you won't see much of a performance gain if you retain that narrow stock piping.

            Actually when I climbed under it I had a nice suprise one of its previous owners had replaced the exhaust with 2" tubing. Hooray for me. I just hacked off the muffler after the rear axle and cut a piece of 2" straight pipe with a flanged end. Clamped it and made my own hangers out of some 5/16 threaded rod we had laying around our shop. Sounds amazing I love it wish I had put a glass pack on it but ohh well.

              Why would you do that? You could have just left the muffler on their........ even with 2" piping that is only 1/4" bigger than OEM. Even with 2.25", you won't see much of a gain. The exhaust can only flow as well as the greatest restriction in the piping.

              For example, in my school there is a hallway that is about 10' wide in one spot, it then narrows down to about 6'. Traffic flows down the 10' part of the hallway just fine. As soon as people start getting to the 6' hallway, it starts getting slower until you are practically stepping on the people in front of you.

              That is pretty much what you are doing when you add a cat back exhaust. Sure after the cat it will flow nicely, but honestly, it won't really do much.

                So you're running without a muffler? I bet the people in your town love you.
