    Tame performance exhaust, but if you are looking for rowdy look elsewhere.  11 months ago
    5out of 5stars

    I have the coupled with a catted Invidia down pipe. The fitment was a little lower from the better then i prefer but it still looks damn good. The exhaust itself has a great note but is pretty quiet. But those of you looking to keep out drone and the decibel level low this is the exhaust. I have little to zer drone at cruising speeds (full interior wagon) but lets off a nice sound when you are in it.

    Great Exhaust 2 years ago
    5out of 5stars

    This is an affordable and well made exhaust. Install time took about an hour including the removal of the stock exhaust. Looks good, fits well, and not overly loud. Has that nice boxer rumble.

    5out of 5stars

    Bought this system about a month ago and its a really great exhaust. have this on my 03 scoobs and it sounds great!gets me notice every time i go for a drive. also helps with the shifting if you know what im talking about. its true what they say, this system brings out that ej rumble and gives ur wrx a nice V8 sound. kind of pricey but well worth it. i highly recommend this exhaust!

    QUESTIONS & ANSWERS

    • Q: Fitment   2007 wrx 1 month ago

      Will this bolt right up to stock down pipe on ‘07 WRX
      • 0 of 0 people found the following answer helpful

        A:  For the best fitment, you'll want to get an OEM downpipe to 3" catback adapter, such as part number: GRM 077046.
