Looking for a muffler that won't rust out too quickly

[89Vette]

i cut mine up for s & g - i have pics in my gallery - that valve does not seem like something that would easily stick

One would hope their design accounted for rust potential. I hope for most owners, that this valve doesn't add another think to replace/worry about.

Not sure if you have any American Muffler shops near you but after my OEM and then replacement muffler rotted out I went to them. $125 muffler and tail pipe installed, muffler guaranteed for life. Also quieter then the OEM was.

Typically, your $125 muffler shop muffler would not be a quiet as a stock muffler....largely because they don't include the [higher-cost] internal packing. (My shop said they could never get it as quiet as stock with their off-the-shelf lifetime mufflers. Actually, that packing also tends to accumulate moisture...raising the odds of rust-out.)
