Thats why im asking the qustion, i like the FI exhaust, but i have seen agency power for under 1000, wanted to know the big differences. I will do research, thanks for giving me a heads up on what to look for when looking at exhaust
. When buying an exhaust for my evo, i noticed the american made exhaust were better, and cheaper most of the time. I bought a AMS one, wish they made 370 exhaust.
