2003 sound
WHamby,
We have been there as well, didn't like it at alll!!!!!! The truck we fabbed up our first 2003 system on was too much of a temptation to run a few miles while we had only the factory down pipe on it. We hated to sound, it was better at higher rpm but other wise wasn't anything we would want. I guess our muffler delete pipe sales will drop off too on the 2003's!
When we installed our system on the 2003 and then it sounded like the old 5. 9 your accustomed to hearing. The sound level is actually the same level as the 24 valve trucks but because the engine is quieter the exhaust note is a little more pronounced.
