jfuller...Honestly I haven't had the gryphon long so it's hard to say about gas mileage. The only time I have driven outside the city with it to get a good gas mileage reading I was pulling my boat. However I did get noticeably better gas mileage pulling my boat around 15.5 on a 300 mile trip. Normally I would only get about 13.5. I'm not a pedal to the metal type of person, I'm more into 40 -70 power and I can definately say that with magnaflow exhaust + gryphon + k&n dropin= great highway and around town power over stock. You won't be disappointed that's for sure. Maybe tomorrow I can take some pics of the exhaust setup and put them in my album if you're interested.

Bill,
I know what I've read, but what do you recommend best for HP & MPG in the Magnaflow line SI/SO or SI/DO on a 5.4L and should I run a 14" or 18" if running the SI/DO ![]() ![]() ![]() ![]() ![]() ![]() GSXRider |
