Pipes make a huge difference in power and performance. When I slapped on the BUKU power pipe in my truck, it felt like I upgraded my engine. It really made a HUGE difference. some people think spending 100 bucks on a pipe is a waste when you can upgrade the engine....but just remember, pipes don't wear out and last forever(for the most part)....engines needs replacing every 4 to 10 gallons. my 2 pennies.
