I just got a monsterflow filter but realized it doesn't fit onto my intake pipe. my intake pipe is 2.5 inches in diamter and the filter is 3 inches. Is there an adapter out there that i can get to make this fit???

 

hmm this is just a wild guess, but you might try a hardware store for like a bell reducer.. from 3" to 2.5 inches then use some flex hose to link them together... I dont know like I say its just a guess... but might be worth a try..
