Borla Exhaust Systems Reviews


Great sound!

Reviewed By Jerome B (Saint Paul, MN) Reviewed for a 2014 GMC Sierra —2/1/2015 10:21 AM

I was debating between the touring and sport exhaust for my 6.2L GMC, and finally decided on the touring. I love the sound and it's actually a little louder than I was expecting, but not at idle or at cruising speeds. I'm glad that I went with the touring exhaust as I think the sport exhaust would have been louder than I wanted. Exhaust looks good and sounds even better!

Snow Performance Water/Methanol Injection Boost Cooler Reviews


Keeps it cool, Spikes the MPG.

Reviewed By Allen W (Bagdad, AZ) Reviewed for a 2008 Ford F-250 —3/12/2009 7:02 AM

The boost cooler really keeps the EGT's down and helps the fuel mileage about 1-2 MPG on my 6.4 Powerstroke Diesel. It does go through a load of the juice so I recommend using an alternative that they list on the site instead of the boost juice because you won't save any money on fuel.
