Doug Thorley Single exit exhuast and SILA cold air intake

Just installed both items. WOW! What a difference in performance and sound. Pulling out into traffic or merging on the freeway now is not a problem at all. The car really feels like it jumps off the line, no more of that lagging hesitation. I highly recommend these modifications. I will report back on how it has affected fuel economy. Currently we get 37 driving hard and 42 with mostly highway driving. Our car is a 2008 passion with about 15,000 miles.
