Is stock SS muffler that restrictive?

[In_style]

I want a better sound, I know to get that, i need performance muffler, how much hp will i gain by changing just the muffler alone? :think:

By changing your muffler you could see about 10-15 horsepower. Depends on what kind you put on it. If you want sound flowmaster is good, but loudmouth is good too.

try 5-8, replacing the crushed over axle pipe will help with flow too
