Its 350HP stock, but with the after market pipes it bumps it up 30 HP to about to the 380HP range. She has a awesome deep throaty rumble. Rumor has it that you can get upto 70 HP out of these with other after-market mods, but the after-market exhaust gave her plenty of power so I haven't bothered with anything more.
That is what.... only 350% more HP than a stock C150.
