How long will a glass pack (Thrush) last on one of our SR20's? I am doing a custom 2 1/4" cat-back next Friday and want to put in a 20" Thrush glasspack as a resonator. (It is perforated not louvered) But I want to make sure it lasts a while. I will have flanges welded on both ends just in case it does go bad (rust out), but I want to have an estimated lifespan on one.

Thanks!!!

hey man, the life of the glasspack all depends on how long you drive it each trip, as the system heats up water condenses in it, so if you switch it off then the water is still in there and will cause it to rust out quicker, so it all depends on how you use it and if it gets to temp, i have seen resonators/mufflers rust out in as little as 6 months while others last years.
