Bosal exhaust for 91 Toyota SR5 4x4 truck

I need to replace my muffler after 17 years and over 300,000 miles.
Has anyone got any experience with the Bosal cat back pipe and muffler
package? RockAuto has them for right at $100.00. A local muffler
shop will weld in a lifetime muffler for $85.00 but that means leaving
work early to get it done. I checked to make sure I can break the cat
bolts loose without breaking them, a shot of Kroil loosened them right
up. Now I just need to know if the Bosal mufflers and pipes are good
quality components before I buy them. Also, does anyone have an
opinion on going with a lesser restrictive muffler rather than stock?
Thanks.
