1 pipe instead of two and the muffler is painted to blend in with the underside. dont know about a difference in sound. just look at pictures.

I've also heard (but not personally verified) that the '05 WRX's come with a single tip similar to the STi stock muffler.

I don't know if its actually the same muffler, but I'd bet it was.

Probably going to start seeing more STi parts slowly make their way onto the WRX to help keep it competitive in the market.

The piping on my stock 05 wrx axleback is only 2.25 i think it looks really pathetic. I heard sti stock axleback is 2.5inches? The tip does look the same though when I had my stock on instead of the espelir, people asked me if I had an sti exhaust or if it was now the same.

The STI piping is 2.5" and the WRX is only 2.25". The tips look the same execpt one says STI on it.

I just put an STi Axelback on my WRX until my Scoobysport comes in. It is a little bit different sound-wise. Has a little deep rumble and you can actually hear the exhaust not just the engine.
