    Take a look in your engine bay and that will tell you how simple it is to put headers on. Overall it is a BITCH haha.

    i got my ory-pipe from jeg's..$149.00+shipping.you can let speedsouth install your exhaust,i live 20 miles south of montgomery,so i called speedsouth for a quote to install,but 750 bucks was a bit out of my price range,i think this price did include a tune though.

    The headers were hard without a lift. I watched my friend install his Kooks on his 98 Formula and it took him like 6 or 7 hours I think. They only charged me $350 to install my QTP headers and ORY, plus $50 to do the catback at the same time so the trouble of trying to do it with jackstands in my shop wasn't worth it.

    Should be able to undo the clamps and slip the LM1 off and the LM2 on and reclamp it. If it was welded then have to cut it off and either clamp the new one on or weld it.

    I like it with no cats butb it depends how loud you want it. No cats will be louder and smells a little at a red light with the ttops off and windows down.

    I didn't even bother with extensions. I used the rear o2 sensors out of a LS1 vette.

    12 in extensions will be enough...

    but it took me and a buddy to put in my kooks 1 7/8 about 3 hours, but that was not real time concerned, Bsing most of the time, and we had a full lineup of snap-on tools and a frame machine....(like a lift but only lifts say 3-4 feet... but is just perfect to work on top and bottom at the same time... but we did another buddies for him he was on a schedule we had him back up and running in an hour and 45... so all depends on how serious and hte tools you got
