Stock catback (2.25" and resonator) vs. SPT catback (3" w/ open muffler):

Stock TMIC vs. STI TMIC (aluminum endtanks and about double the volume):

We also installed a [modified] air splitter and rubber seal from a STI so the WRX scoop is able to effectively feel air to the larger STI TMIC. We replaced the couplers with 4-ply Vibrant silicone couplers from MAP.

The exhaust is a few pounds lighter than stock, but definitely a lot better looking and more free flowing.

Janelle is very happy with the gains she picked up last night and she is happy with how the new exhaust sounds. Once the catless downpipe is on, the boost is raised, and she gets it dyno-tuned it should be a real STI killer!
