Frank, first of all, who made your original muffler ? I can't believe how restrictive it is !!!
You probably gained 100 hp ! lol
I love my Stainless Specialties muffler and 304 stainless system and I will NEVER,....go back to a packed muffler or mild steel tubing. Although their expensive, they should last many, many,.. years compared to mild steel, any type of packing and ceramic coatings. The way we make our system, the muffler is press fit inside instead of having welding tabs that always will break loose and make noise. The collectors and turn outs slide between the muffler shell making for clean tight fit and requiring just a small tig weld.
The stainless is easier & faster to clean than ceramic coatings.
I love them and you will too !
