i have the ACS exhaust, i had gone to an after market performance shop. i wanted to check the pricing on SS headers and cats. The guy at the shop was telling me that the ACS exhaust is all looks and sound and no go! He was suggesting an exhaust change for better performance.

is this guy bulling me, or does the ACS exhaust really give no gain?
