Looking to buy a cat back exhaust for my 2000 acura integra gs. Some guy is selling a catback that was on his ek, the type of exhaust is a Mandrel bend 2 1/4" catback. he said that the bolts would not line up and id have to get it welded. Does anyone know if it will fit? And is it worth it?

 

What's the seller asking for it? Compare that to the cost of an OE and go from there. Most exhaust shops will probably charge $50-100 for the labor. I would go OE.
