    Brutally loud if you have an offroad midpipe. Subtle otherwise.

    June 04, 2014

    Pro's: Easy to install. Lightweight compared to stock mufflers. Offer a unique exhaust tone. Con's (personal opinion): With my offroad H-pipe these mufflers were brutally loud & popped a LOT during downshifting. The exhaust tips look a bit small on the car. The tips are also 'unique' looking...some will like, some won't. Personally, if I keep this setup I'll definitely replace the tips with something else. Other: I felt the overall loudness of these mufflers with stock manifolds and midpipe was similar to the stock mufflers. However it does provide a unique, deeper tone and less of the 'burble' effect the stock gt500 mufflers produce. Note: You'll need a 16mm socket for the tip clamps (it's not mentioned in the installation instructions)
