03 2.0 DOHC exhaust question
 

Ok so I'm trading for an 04 2.0. Not new to ricers, but new to the Tiburon. Looking for parts I find endless headers for the 97-01 2.0 for next to nothing. And barely anything for the 02+ and when I find it, its WAY more. My question, whats different between the first and second gen when it comes to exhaust? And can the 421 and the like from the first gen be made to fit? I dont care if I have to break out the welder for the downpipe. Its better than spending hundreds more for the same thing.
