Default Torque Specs For Lugs and Exhaust

Hi guys... Can anyone please confirm the proper torque specs for the following:
1. Lug nuts
2. Exhaust (when bolting on the Tanabe)
Thanks!! BTW: I am one of the few gals who actually gets down and under..the car that is; to do my own work.

I'm going to say 80 ft lbs for the wheels is the best for OEM set up....
(others might say 76 or 78 per the Lexus tech guide)

Sorry no exact info on exhaust specs, just don't overtighten is the rule of thumb I use.

DIY is always the best way!!!

Thanks guys. I figured the lugs where about 70 to 80lbs but was unsure about the exhaust. Hand tight is about 30 to 40lbs. When I played with my S2000, I was always careful to "torque to spec". Believe it or not, Honda lug torque was 63lbs. I torqued to 80lbs regardless of what Honda specified.

Be glad your aircraft mechanic is not so careless about following specifications.

Oh ******! You're right about that! At least I check the specs and torque accordingly. I bet most people don't even give it a second thought.

Six of my 20 years in the Air Force was working on aircraft. There's no magic in machines, only engineering. Fastener science and the supporting material science is not a black art, so, I torque to spec. All the time.

Off topic, sorry in advance. Lobuxracer My husband was Air Force also. I think he called it combat control, or something close to that. He served with the special forces of other branches for many years before he was injured and went into the medical field.

Back on topic... thanks again guys for the torque info.

I never had a problem in 6yrs 9months of torque'n all 4 lugs & 1 lock the same spec... (oem & aftermarket)

You actually risk the chance of losing it. (in my opinion)

They should always be the same spec.

How dangerous is it just hand tighting the lugs. Im asking becoz this is wat i do.
Obviously it might become lose while driving but wat are the chances of that happening?I did it 4 months now and wenever i check its still as tight as the last time i leave it.
I need to stand on the tire iron to get it lose.
