I previously had a Bosal front header that lasted almost 3 years in snowy upstate New York. This leaks at the flexible joint shortly after 1 year. Low quality. I also bought a Walker SoundFX muffler which rotted a little over a year ago. They do not grant SoundFX pipes or silencers. now i know why Lesson learned. AVOID cheap Walker products. Maybe their Quiet-Flow SS series is better, but the ones I've tried are short-lived.
