HKS exhaust

Sounds awesome! I wanted something a bit more practical and clean sounding than a Tomei, and this works great. One star off because of the mounting - it doesn't fit with the stock STI underbelly diffuser, I had to chop off a strip of it.

Best catback for the price

Looks awesome, fits great, has an awesome rumble sound, but isn't excessively loud. At $500 its the best bang for your buck for sure.
