No worries...hope to see you there

Thanks bro! Good meeting you too.

Yes sir! Stock internals and JUST a RPi X pipe and non other mods.

The variance is there because of the weather

I know! I was surprised myself! The RPI x pipe deletes the cats and resonators

Joe: Congrats on getting into the 600 club!
Seriously it was loud in Tom!

Weather conditions.

Congrats on the huge gains!

I don't think just adding mufflers will gain anything.
