Hey guys, so I have an 89' Trans Am with the L98, I recently sent my block off for a rebuild and I'm having trouble finding headers that will run with my stock computer and the single o2 sensor. I have hooker shortys from my old 87 Z28 305, but my dad says the wont run correctly with the computer. Anyone know what headers won't have any issues with the o2 sensor and still fits the stock y-pipe, I figure I might as well get all parts I can in while I have the engine out. Doesn't need to be obnoxiously loud or anything but maybe just a nice sound like my brothers here. https://vimeo.com/58812840
Any help is appreciated, thanks guys!

Nothing but stock junk will fit the stock Y pipe. Get long tubes and a mufflex Y pipe with o2-s in it.

Only one choice in shorties: Don's.

Quoted for truth, EVERYTHING ELSE IS JUNK!

Hmm, wasn't aware of that. Thanks guys!

SLP Shorties, Dyno Don shorties, Hooker 2055's, Edelbrock. All come with Y-pipes, and will work with youre computer. Youre old ones will probably work also, if you can get a ypipe fabbed up from a shop with a bender. Not as hard as you would think. Alot of exhaust shops do this now. Long tubes work, but for 1-2HP, not worth the extra hassle to make them work. Just get short tubes with the matching Ypipe. 3" High flow cat, and quality 3" cat back, like Borla or Magnaflow. Depends on what sound you prefer. Unless youre putting down over 500 to the Wheels! That setup is more than enough.
