Hi All,
If you had I lift and all the right tools how long would it take to install a set of long tube headers and free flow cat x-pipes on a "08" C6 LS3?
Thanks,
Mike

3-4hrs..If you have never done it before, easier than a C5..

LS2-Zomb!e

2-3 Hours

I am sure you will be told it can be done in less than two hours, but plan on 4 so you don't have to rush. Also make sure you have all the correct parts before you start, nothing worse than starting a job only to find you have 3 rear o2 sensor extensions and 1 front or worse 3 fronts and one rear!

Good to know even though I don't plan to put headers on my car.

Its cake. I did the headers in my driveway with ramps only in about 3 hrs. Couldnt be easier. Reuse your stock gaskets and tighten the header bolts from the center bolts and work your way to the outside.

FYI, always be safe when under the car. Double and triple check the car for stability before getting under it. Be safe and enjoy the install.

3 to 4 hours should be fine for the first time. I just put LG Pros on my C6 in the driveway on ramps. About 3 1/2 hours. The easiest header install I've done. More room than most cars.

In a perfect world, for people who are mechanically inclined & I am (built my custom Harley from scratch starting w/ aftermarket frame to building the engine to lacing the spokes) & I installed my headers, I agree w/ 3-4 hours. Real world, if you're by yourself, 1st time & you don't do this type of work regularly, then ALL DAY! I did mine in my garage, alone, & just getting it safely in the air took 30 mins. The catback aftermarket (Flowmasters, crap BTW) exhaust had rusted together took longer to break apart than removing the enitre rest of exhaust. So if you're looking for an estimate on how long it should take a shop or you in a friends shop w/ their help 3-4 hours. If your on your own, w/ access to a lift & the tools having never done before count on twice as long.

Depends on any number of things. If absoultly no problems and you have a lift and experienced help, yeh 3 to 4 hours best case. Worse case alot longer, all day maybe. Then hope you don't have any flange leaks or a warped header flange. Then take it off and put it back on. Ask me howI know.

I contacted a few places and was quoted between 100 and 150 dollars for the install if I also had a tune done at the same time. Being as a tune is highly recommended it almost seems worth it to have someone else deal with it. But, the shops I contacted said it's a 90 minute job.

It took 4 hours, start to finish, solo, on my car. DynaTech 1 7/8" with cats and x-pipe. I took my time and I'm a meticulous wrench turner. Honestly, if you can screw in a light bulb, you can install headers on a C6.

Running the o2 sensor wires is the toughest part.

The Clevite Kid

Tough as in difficult, or just time-consuming? I have seen one recommendation, (from SpinMonster ??) to drill holes in the tunnel plate to run the after-cat O2 sensor wires above the plate.

Any one have details on this approach? I have my Kooks with ceramic coating in the lab, and had MarylandSpeed weld in an extra bung in the merge collector for a wide-band tuning sensor. I have a lift in my air-conditioned lab, and lots of air tools, and a couple of experienced Corvette (amateur) wrenchers to help. No beer until the job is done.

Wish it were that easy on the 948

the xpipes I am looking at have the cats just after the header flange besides on the ls3 my o2 sensors wires seem to run along side the stock headers now.

O2 sensors are not difficult, & there are some nice pics of Spins rec. out there on the forum. That's what I did, used a few clips mounted in alum. tunnel plate using the mounting screws already there. It's only time consuming 'cuz you need to take a good look & think a little where the best place to run them is, best spot to clip to support away from heat, etc.
