Has anyone done this before? cuz for what i know that muffler is intended for a WRX i dont know how good it will sound on an Sti and if it would take some ponnies out of it? so please i need coments on Sti owners using this muffler.

Thanks

 

Anything that's exhaust component for a wrx will work with the usdm sti. Same benefits, I don't think there are any losses since they're interchangible.

I only know that some items, like an exhaust, will sound a little deeper on an STi, because of the extra displacement.

don't waste money on an axle back.. get a real 3" exhaust system. Trust me.. you will not be disappointed.

 

I have a scoobysport on my STI, its similar to prodrive. I feel alot more low end response when i put it on. The sound is definately deeper i guess, as i compared to other subies and its only an axle.
