Drone is the worst. I had flows on my 04 Mustang GT, combined with an MRT-H pipe. Between 2200 and 2500 it would rattle the change in the cup holder lol
Awesome! Definitely waiting to hear the exhaust on the 2.3. If you guys follow through, they might be the first videos on record of a 2.3 exhaust upgrade lol
Maybe I missed something but has anyone weighed these and compared them to the stock exhaust?Hey everyone! We just launched SEVEN NEW exhaust systems for both the 2.3L and 2.7L models here at Holley under the Flowmaster brand name.
