Test Pipe or HFC?

Sales@AAMComp

test pipes
pros: best flowing, no restrictions what so ever, yummy gas smell?
cons: WAY louder in comparison to hfc, both rasp, drone, exhaust note, a good alternative to this are the ART pipes, which have a separate resonance chamber. some are made with the j-tube style o2 bung to trick the o2 sensor for no CEL, some don't. Smell (some hate it, some actually love it)

high flow cats
pros: no smell, theoretically shouldn't trip the o2 sensor, should flow similar to the test pipe, but obviously not as much
cons: more expensive, cores can possibly break or come loose, especially if you track your car, the excessive high temp exhaust gas will have an effect on the core
