Calif 1979 - TA 403, RV Cam / new Spintech muffs
Posted 16 April 2017 - 08:30 AM
I was looking for a louder throaty sound?
Gotta keep it legal with the Catalytic Convertor am I limited as to getting that Throaty sound?
Will removing the crossover help or am I doomed to just a slight rumble?
Or did I pick the wrong muffler?

I like flowmaster mufflers. they do make performance converters but I don't know if they are legal in your state. doubt the crossover is hurting your sound
