I am trying to build my own exhaust for my 96 accord instead of buying a premade one. I was thinking about buying some stainless steel piping and using a pipe bender to bend it into shape then buying a muffler and I'm not sure if I would need a new cat. converter. I'm thinking this might be a bit difficult so I was wondering if anyone had any suggestions...

you probably will need a new cat conveter to handle the added hp. the hp isnt much that is added but if you want it to sound better i would get a new one.

why do you want to make your own?

for fun of course! I just got into "playing" with my car and I figured why not have some fun. I mean if it doesn't as well as a bought one, oh well, but I'll also learn stuff doing it

That's cool. Um, you wont gain too much hp, but it depends how much of the exhaust you plan to replace. If you are going with a homemade cat-back system, then you really don't need to replace the cat. But personally if you are expanding the diameter of your exhaust pipes then I'd get 4-2-1 header and a hi-flow cat, and then build the rest.

thanks, over time my idea has gotten a little shot down so I think I'm just going to get a high flow cat and maybe a muffler or somthing. I've looked around and from what I have found I think it would be a little too difficult to build it. Thanks for the advice though!
