Ok I'm wondering if I'll lose horsepower or torque by removing my MBRP performance muffler, and putting in a MBRP muffer delete straight pipe in it. Its on a 4in dual system and i don't wana pay $118 bucks to lose power but i do want it louder

 

you arent gonna loose power

 

You won't lose power but your mileage will go down. You'll be having to much fun during diesel into noise.
