Corinthians played some lovely stuff early in the tie and took a deserved lead when a 30-yard free-kick beat the diving Adam Perry.
It took a rocket from boss John Bailey to inspire off-colour Featherstone, who levelled with a towering header from the hard-working Kyle Pearson. On 37 minutes the speedy Andy Catton fired home a Simon Davis pass.
On the restart the visitors showed a determination sadly lacking in the first half. Rich Longley struck inside five minutes and Gareth Catton fired home just inside the hour.
Driving forward by Pearson, Michael Seed and James Bradley, it was one-way traffic. Pearson sent Longley clear to hit a second, Chris Appleyard found the target with a fierce 25-yarder and Gareth Catton cracked an eight-minute hat-trick, thanks to the fine work of Seed, Pearson and Longley.
Simon Davis skilfully slotted home a precise pass from Andy Gray to complete the rout.
Pearson, Gareth Catton, Longley and Murray were the stand-outs, with the Davis brothers, Gray, Appleyard and Seed also impressive.

Pontefract Amateurs ...3
Fryston ...0
Premiers Pontefract overcame a tricky tie against the Division Two leaders to set up a quarter-final tie against Castleford Town.
Amateurs, who had only a injury-hit bare eleven on duty, made the perfect start when Ian Hutchinson rose highest to nod Steve Limbert's free-kick into the path of Andy Burton, who sweely volleyed home.
Fryston responded but made no impact on Lee Ward, Limbert, Mick Tudor and Frankie Lynch and late in the half Burton did the hard work to set up Paul Hegarty for number two.
Burton was at the heart of the hosts' third goal, forcing the error that enabled Scott Timms to charge down a clearance and tap home.
Wayward finishing prevented further goals as Dean Kneafsey, Craig Tankard and Hegarty pulled the strings and a superb finger-tip save from Jason Hoare ensured Ponte' kept their first clean sheet of the season. Limbert, Tudor and man of the match Burton were best.

Castlefields ...2
Brotherton and Byram ..6
Much-changed Byram will play Premier Division rivals Knottingley Waterside in the semi-finals after this dominant display against physical opponents.
The recalled Si Haddock fired the Premiers ahead on eight minutes with a sublime finish from Rich Priestley's lovely pass. Jamie Middleton had a 30-yarder tipped on to the bar before keeper Si Hudson gifted the home side an equaliser.
Haddock restored the lead three minutes later and William Hicks made the game safe on 55 minutes, tapping in from three yards after sub Matty Haddock's shot was blocked on the line.
Priestley rattled the bar before Haddock rifled home following good work from Middleton. The pacey Adam Priestley showed the home defence a clean pair of heels to convert Middleton's precise pass and though the home side hit a second, Middleton ensured Brotherton finished on top after good work from Danny Graham. Rich Priestley was the star-man, pushed hard by Si Haddock and Middleton.
OTHER RESULT: round three: Chequerfield 0, Knottingley Waterside 3.
