Mhm. Exploud isn't meant to be bulky. It's Hp aside, its defensive stats are crap and his typing is mediocre at best. He's meant to wallbreak with that set.
Ferrothorn works fine, although you may want to rework the spread 252 Hp / 48 Def / 208 SpD Relaxed is the standard for Ferrothorn. Also, leads mean nothing in 5th gen, thanks to Team Preview. I personally perfer Ferrothorn to Skarmory because of Iron Barbs and the resistance to Water-type attacks.
You'll really want to change the nature. Exploud needs every bit of power he can get behind his STAB Return. Also, is this 5th Gen? See if you can't get Scrappy yet, it's a majorly good ability. If you do, Ice Beam or Thunderbolt > Crunch.
Hi-Jump Kick now has 130 Base Power. Combine that with STAB, STAB Flare Blitz, Swords Dance, Speed Boost, and Blaziken's Base 120 Attack stat and you have a Pokemon that just punches holes in even the bulkiest opponents. People were having to run bulky variants of Intimidate Salamence and fully defensive Regeneration Slowbro just to check the thing.
