Tomorrow I'm goin to oriellys and order a set of patriot long tube headers and 3 inch piping. My question is will the headers have the ports for o2 sensors. Can a exhaust shop port the piping for o2 sensors ? My exhaust set up will be long tube headers and a small x pipe and dumps no cats or mufflers
ill be putting it on when I do my cam swap. Ill have to drive the car open headers to the exhaust shop to get the rest put on. That shouldn't hurt my valves as long as the new valves are warmed up? Tune will be after exhaust same day though. Cam kit is a trex from thunder racing! Should be a mean car. I have a centerforce clutch should I have it rebuilt or get a new one? There pretty pricey

if the headers are ment for an ls1 car then yes they should have the O2 holes and if they dont if you be easly done by any exhaust shop. All they have to do is weld in O2 bungs. If I were you i would not drive the car to the exhaust shop with the car not being tuned for the cam. I would have the car towed there and then towed to the tuner. As for the centerforce clutch how many miles are on it? I've seen a few centerforce clutched taking some beatings in my day and it should be fine for a cam only car

Never thought about hauling it? That's a good idea to save a head ache.I'm unsure on miles but its hard for me to shift gears it needs a good bleeding or a master cylinder or slave cylinder. My cats on my car are clogged it will barely run at idle and is real boggish now and won't even hardly break loose in second. That's a big hp drop. Nice car by the way

I'm not sure what You meant about not hurting You're new valves as long as they're warmed up but just an fyi ,,,,,,,in the winter or cold weather especially valves can and will warp with no exhaust or not long enough exhaust after shutting it down ,,,,,,,,,,,valves hot ,,,,,in coming air up the short exhaust cold ,,,,,,,hot and cold mix n warp a few valves as they're cooling too quickly .

That's also a good thing to think about. I'm running a small x pipe at the rear end I figured that would be long enough and enough back pressure. I also will let my car warm up before drivin it any

How big is this cam you're putting in?
My friend just got a 224/228 cam put in and drove with him back from the shop and monitored the car with hp tuners. Part throttle and idle the car learned the new cam fairly quick and after a few minutes his trims were -3 to 3 which is more then acceptable. WOT he needs a tune, but there's no reason why a relatively small cam will not be driveable without a tune. That's what the o2 sensors and computer are there for.
Now if it's a big cam then you would need a tune just to get it going, but don't be scared to drive the car easy even with an untuned cam.
