Methfireroad Posted March 4, 2013 Report Posted March 4, 2013 This year I'm stepping up to a 421cub. I have been talking to some people about exhaust. Shearers vs cpi. I'm going to be running 28 pwk for now tell I buy some different carbs. I would like to know which ones will give me the most bang for my buck. Also which will give me the most hp.. Quote
lms1977 Posted March 4, 2013 Report Posted March 4, 2013 Lol ^^ really I mean search a little there has to 10 topics this year already sorry to sound like a dick Quote
camatv Posted March 4, 2013 Report Posted March 4, 2013 both are good pipes. cpi has a lil more low end but you cannot get to the plugs or your shutoff very good. but the fit an airbox. shear is a lil more on top but some dont like the way they fit they work best with no airbox or a majorly cut down stocker. either pipe should work just fine.
