dual exhaust/ hood scoop

yeah i think i spelt exaust wrong dual too. Anyway i got a 91 sunbird 2.0L 4 cyl. OHC, and i was wundering if i could put duel exaust on car? or could i split it after the catalitic converter? (can u even find pipes that are made for 2 cylinders for the first part of the exaust?) i was just wondering. I was thinking about doing this not to be crazy but for better performance i wanted to take the hood of my car and cut a spot out where the hood scoop would go and then have it sealed around the edges ofcourse and have a button insode of car and have it raise up and down with the button? (like the old car that had it (muscle car i think)(not sure of the name of it)(maybe it was the road runner)) and have the air come through the scoop then into the carb. like the old cars.(not sure about dooing scoop) im thinking about putting dual exhaste on it.

duel exhaust is easy. You can do it after the cat if you would like. as far as true duels that would be expensive seen it once though. Two custom headers or you could do a single header 4-2-1 and remove the 1 and just amke it a 4-2. many choices

just cut after the cat, get a Y pipe, build exhaust from there....not that hard....

yeah that wouuuld be cheaper too. i just have to look at car first cause i have to see if i can fit another pipe under there or just run them next to each other.

you should have enough room..

I hear 91 Sunbird GTs had dual exhaust! Something close to this:

the only thing is that the exhaust on their now and it follows a groove in the bottom.
