Will just the SS mufflers and X pipe give you hp gains ? or just the stellar tone.
Thank you for the reply!

The Supersprint Mufflers and X Pipe will give you HP gains. It is not a substantial gain, but you will benefit from the improved exhaust flow. The main benefit is the stellar tone! It really sounds awesome!
