I stayed with the same diameter pipes. I was told that power would suffer if I went larger. Didn't want compromise power just to increase the sound level. It was just a basic muffler swap-out, and chrome tip install.

and.. yes! there is a difference in feel! I can't really give you any % of change, but it IS noticeable. (I can give you a SWAG of maybe 5% more power) Throttle response is wonderful! I have to be careful now of how much I squeeze the gas, because I tend to listen to the tone of the exhaust more than I watch the speedo! LOL.

If you want, I'll post a sound clip tonight.
