What's it take to go from dry to wet exhaust ? Is it just a tail pipe change?

Yes that is basically all it takes BUT you must make sure the cam your running will not cause reversion with a wet exhaust . Dry tails = No limitation on cam selection and more sound , loud . Wet tails = Limited cam selection with a chance of reversion and less sound . I am going with totally dry pipes and mufflers to extract every ounce of horsepower .

Thanks that helps !
