Write now,i have an 01 coupe.I Have the zo6 cats on followed up with the corsa x pipe and corsa indy exhaust.Im thinking about putting lg longtube headers on.My ques is,Can i just put the headers on or do i need to change my whole exhaust system all the way back to the the corsas.
I believe that people have modified, or just used, the primaries from longtubes with stock cats and H-pipe. My question would be 'why'? The complete system with x pipe adds great power. Keeping the stock H-pipe would partially negate installing headers.
Check with the manufacturer of the headers to see if you can keep your Corsa x-pipe. There may be some issues with how they match to end of the headers. As the other gent said, the A/R's should be at the top of your list.
The ARH system eliminates your need for the Corsa X pipe.......I have their system with hi flows and then just sold the X pipe here on the forum. Best thing about the Dr's system is the merge collectors location

contact TPIS, can google them for a number. their long tube system is specifically designed to connect to existing header back piping...believe they provide a new H pipe as well....
