I'm looking at a set of headers for my '72 Chevelle SB from OPG. I have the option of 16 or 18 gauge primary tubes. If everything else is equal, wouldn't 16 gauge be better ?

'72 Chevelle (2rd & 4th owner)

the 16 should last longer and sound quieter.

70 L camino, grampa engine, g-force 5 spd, road rage suspension. Pray first before all else fails.

keep in mind ceramic coating helps increase the header durability, and tends to reduce rust , and remember heat and cooling off in moisture is the thing that is causing most wear, heat is related to the fuel/air ratio and ignition timing , if the engine runs lean or the timings retarded exhaust heat tends to increase.

IF YOU CAN,T SMOKE THE TIRES AT WILL,FROM A 60 MPH ROLLING START YOUR ENGINE NEEDS MORE WORK!!"!
IF YOU CAN , YOU NEED BETTER TIRES AND YOUR SUSPENSION NEEDS MORE WORK!!

The smaller the gauge # the thicker the metal.

16 gauge is .060 thick
18 gauge is .048 thick
