Performance exhaust question
Hello Out there
I am opening another topic on performance exhaust system for 2001 Porsche Boxster Base.
I am torn between the maxflo system w/o performance headers or the supercup system.
Just wanted to hear your opinions between these two systems. Seems the supercup is emissions compliant but a more aggressive sound. I am just trying to understand how aggressive it is. I would like to try to get a little bump in HP. Thanks for your input
