Exhausts

Do you want a header or just the exhaust pipe?

You can get custom 2.25" and that will be plenty. No one else sells bolt on exhaust though.

i know , but all the places ive called were so damn expensive. could an exhaust for another honda fit by any chance,. and im just looking for a cat-back

No, the only exhaust that will fit is the pacesetter or a custom one. Pacesetter is only $200, i have it and i am very happy with it. The best size pipe for our cars is 2.25" which is what the pacesetter is, so even if you bought the exhaust system and put a different muffler on it, it would probably still be cheaper then having a custom one made. If you have no major engine work done then all you need is a pacesetter system.

When I was designing my exhaust I wanted the header tubes themselves to be between:

28.375" and 30" long primaries and the exhaust system to be another 28.375-30" long and only be 2" in diameter.
2" being 20% of the primary header tube diameter which is 1.625" or 1.75" in some instances. You may be able to use 15" - 18" lenght of 2" pipe after the header, but shorter pipe usually shifts the powerband higher.

The stock exhaust system both EFI is about 26" long and Carb 18" long to the point where all four cylinders merge into one. Which still doesn't seem right to me but I did have the exhaust off the car at one point so I don't see why I would have measure it wrong.

After you've runthe 30 some odd inches of 2" pipe you can pop on 2.75" catalytic convertor or muffler if you can fit it and are not running a cat (basicly about an inch larger then the exhaust pipe), then adapt the pipe from the 2.75" cat to a 2.25" pipe to a 2.25" - 2.5" muffler.

Cat:

Random Technologies or Magnaflow.

Notice how the pipe enters the cat and exits the cat and how the merges are.
By allowing the exhaust to expand at the tunned length, having a cat no longer becomes a hinderance to making good performance... also by having a large cat you get more flow. Now with a muffler in the place of the cat you'll proably be better off but this is for cat legal systems.

This is actually an instance where having a straight pipe (Test Pipe) is bad because a straight pipe doesn't have any place to rapidly expand the gasses so you lose the tuned lenght, if you ran a tuned custom header etc.
