I have an opportunity to buy a catback that is on display at a store that is getting rid of it, the only problem is they are not sure what model it is for. I have a 99 honda civic si coupe, is there a big difference in the 2/4 door catbacks and the 3 door catbacks.

 

That's easy; call the manufacturer and ask them what model that part number is for. Don't take a chance.

 

Who is it made by?

 

the 3-door piping is shorter than the 2/4 door piping.
it won't fit.

 

Well I went back to see if the exhaust would fit and found that they had a Warlock Cat-back for a 92-95 Civic Si and even though I have a 99 it fit and sounds great. Got the exhaust for $50 and had it installed for $80, what a deal.

 

Warlock catback? Never heard of it. don't tell me, it's a fart can isn't it...
