losing mileage and perf?
So i had my muffler shop straight pipe my truck for 10$. I love the way it sounds but every one tells me im losing gas mileage and performance. Is this true cause i could not really feal a diff and I have no idea about the gas mileage. Would i be better off replacing the pipe wiith like a magnaflow or flowmaster as long as it still has a good sound? and i wanna keep it a si/so.

Performance actually improves with straights (as long as the pipes match and are installed smoothly).
