460 headers/magnaflows

Just for all's info......Iam waiting for the header kit from Gibson.....10 days now....I guess they have to make 'em.
Now, on the $111.00 ea straight thru muffs.....they are straight thru ok and offset inlets too...however if you look inside the inner straight thru tube ...at each end where it turns to go to the opposite end is a fairly hefty kink in the bend......really setting up for turbulence.....A N D ..they claim 100% stainless.....well sort of......well not quite ....seems there is stainless , then there is stainless alloy which contains other metals which these are. the end pipes are not straight out either.... I like to weld all my exhaust joints.....didn't think I would be able too...so ordered SS band clamps then find out its a weldable SS alloy....wasted some money....
Pure SS is not magnetic....these Muffs are.....
Is there anything we can depend on anymore.......

  • What did you expect? Stainless that you could polish? You won't get that at the Gibson price. You didn't waste your money though. The grade of steel in those pipes and mufflers is more than one grade above Gibson's regular steel ones. They will outlast the RV. The headers are made from slightly better stuff and will discolor, but won't look rusty.

    I've had the full Gibson SS exhaust for the last seven years and it's been great.
