#Mufflers

Sajeev,

Is there some solid information out there about how various mufflers perform and sound? Mine are rusted out and need to be replaced (’96 Chevrolet Suburban 5.7-liter, true dual exhaust with crossover). I’m finding lots of baseless opinions, but little fact. Many forum posts keep referencing someone’s test with a Mustang and fifteen mufflers from 2002. Or some chart showing “flow percentage” but with no reference to who or how this “test” was performed. Perhaps you have some direction?

Also, do you or the B&B have suggestions for quality forums for this Suburban? I’ve not owned much ‘Murican stuff before and am a bit overwhelmed at the quantity of forum options.
