Challenge Sport catback Exhaust with Challenge downpipe with High Flow Cat. The downpipe added a good amount of grunt down low and in the midrange without adding any additional noise at crusing speeds. The cold start is now a bit louder than before and the over all exhaust note is a bit deeper with a hint of turbo noise in it
When the Ecu is put in sport mode, you also get a bit more burble and poping noise off throttle
